Server 2 nics issue

Q: Server 2 nics issue

We have a Windows 2003 server with two nics in it. Nic one is for user access to the server (192.168.215.27), Nic two is connected to a switch that is used for tape backup purposes only (10.10.0.16). The server is running our testing software from QuestionMark and everything is working great. But they have a tool that runs from users desktop called Author Manager that allows testing administrators to edit test question, answers and scoring.
Okay here is the problem, as long as nic two is enabled the author cannot connect to the server. If disabled then no problems at all. No routing is enabled and a persistent static route has been added to tell all 192.168.215.0 traffic is to use the default gateway of 192.168.215.1 only. We have seen this before with VPN client connections because checking with a tracert showed that the last connect was to the 10.10.0.0 subnet, but adding the persistent static route would correct that problem. QM support will only say that they do not support 2 nic servers, which I find silly.
So the question is has anyone had this issue before and is there a way to fix it. And if routing is disabled why would a nic pass its traffic off to another nic. Is thier anyway to force the two nics to isolate themselves from each other.

Hi Guys,

I've got a PC running 2003 Server that has 3 NICs installed. One NIC is for the WAN connection, One NIC is for a LAN network on the 10.x.x.x range and the last NIC is for another LAN network on the 192.168.x.x range. As the two LAN networks are on different IP ranges, how do I get these two LANs to be able to talk to each other (such as PING etc)?. I unsure of how to set up static routes so if any help can be given it will be great. Also how do I bind IP addresses to the NICs in 2003 Server. Once again, Thanks

A:problem of 2 NICs on Win Server

Hi, hopefully this will help you understand what is happedning.

When I set up my first service running 2008 with two NICS, I had a read of the following. Please note it is quite detailed, but it's a great education resource and should help you get your head around what's happening.

You didn't say if your clients are using DHCP or static addresses, or if both the NICs are configured on the same or different subnets, or of there are any switches or routers in the network, so I'm making a number of assumptions here.

Hi there,

After a hard drive failure, had to reinstall windows 2000 server. Pre failure the set up was like this, and worked without a problem.

1 server - win2k - dhcp.
4 pcs - all dhcp enabled to obtain from win2k server. Call them A,B,C and D.

3 of those pcs had 2 nics installed, which are for internet connection. 1 of those (A) obtains its ip from an adsl router that has dhcp.
The other two (B and C) are assigned fixed ips (as given by the isp).

Now, the set up is exactly the same, but when the NIC that is on the LAN network is enabled, the there is no internet access. Once it is disabled, internet access is restored. Is this a DNS issue?

DNS and DHCP are enabled on the server. The NIC on the server is assigned a static ip with the same ip given as the dns and the gateway.

Any help will be extremely GRATEFULLY received as this whole episode (rebuilding the server) has been driving me insane.

I was able to successfully perform a 'remote client installation' of Ghost on 2 PC's, each containing 3 NICs by disabling all but my main network connection and then installing. (NOTE: You also have to be sure you are doing a 'clean' install. If you try and it fails you may have to manually clean all Ghost entries out of the Registry to get it to install) After the install completed I re-enabled the NICs necessary for normal operation. Then, In Ghost Console, right-clicking on the properties showed an error stating 'multiple NICs found ...', I followed some online advice and went into the configuration IP/Netmask settings and hardset the ethernet card template to the one I wanted it to use. Once that was done I was able to complete a clone/backup Task on the first PC successfully. However, on the second system, which happens to be 17 miles away and a little difficult to get to, it's not working. I can trigger the Task to clone, and through a PCAnywhere session to the remote PC I get a prompt saying that an Admin. task is starting to close all windows, so it's talking, but then the Ghost Cast Server session waits for it to complete the reboot and join the session to begin the backup, but it times-out.

Hello all,

I have been looking for several days and I have yet to find any machines for sale that offer dual NIC support. I have tried looking at the typical sites, including Google but to no avail. So, I figured I would look for help here.

Ideally I need a box that uses the atom processor (low power), dual network cards, and has a relatively large hard drive (500+ GB).

Anyone have any suggestions?

I looked here: http://www.newegg.com/Product/Product.aspx?Item=N82E16859110001 and found an almost perfect match. The only problem is that it does not have dual lan which is a requirement for me. I could go and purchase a USB network adapter like this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16812146017 but I don't see that as an ideal solution compared to dual onboard network ports.

So, reaching out to see if anyone knows of a box like this that has dual NICs for a reasonable price (under $500 US).

Thanks!!!
 

A:Looking for Linux Intel Atom Server w/2 NICs & large HDD

I'm not sure I know of any Atom based units that have dual-NICs. A machine you might want to consider is something like the Acer Revo 3610 (I'm thinking of getting one of these - since you're in the US it'll probably be half the price over there). The unit comes with an dual core Atom 330 (I believe this shows up as 4 CPUs because it has hyper-threading on each core, or so I've been told), 4GB or RAM, and a 500GB HDD. You could then purchase a USB-to-RJ45 adapter.

Please let me know which unit you buy, as I'm very interested in doing the same (I want a low power consumption Ubuntu server).

Hi,

I am having an issue with offline files created offline syncing back to the server. I have set up a network share to be available offline on a client computer. All files are available offline without issue. Here is the issue however. If I set the folder to work offline any file I create in the folder when it is offline just disappears when the folder comes back online, there are no conflicts or sync failures reported in sync center. If I create a new folder offline the folder does sync back to the server. Any changes made to an existing file are also replicated back to the server once the share is back online. So the issue is only with newly created files when the share is offline. I have not been able to replicate this error on any other file server in our environment, However I have recreated the issue with multiple shares with multiple Win 7 clients on this file server.

Steps taken so far.

Checked and reset permission levels on the share.
Recreated new shares from scratch for testing.
Disabled and enabled offline files on the client computer and cleared the offline cache.
Check various registry entry settings.
Disabled cashing on the File server.
Tested with XP the issue does not exist with XP.

I have spent hours researching this error online to no avail.

The clients are running Windows 7 Enterprise 64 bit
The File server is Server 2003 Standard 32 bit with SP2

Any help or ideas would be most welcome.

Out of sheer curiousity. I was wondering which would yield better results an onboard 10/100 lan or a pci 10/100 lan card. Not that it makes any difference in your internet speed i woud just like to know which is mathematically better. Correct me if im wrong but doesn't the pci bus have a 133 MB/s bandwidth? Even if the pci card is only capable of running at 100 MB/s. I guess my question is really how much bandwidth the onboard lan has. Which im sure is more than 100 MBs.

Hello,
I have 2 machines running XP. Each has an on-board NIC and an add-on one. Pls don't ask why: I don't know.
Both machines are connected to the internet via a router.
Would it be a good idea (i.e. would it improve performance) to do the following:
Use one network connection for Internet access only, with TCP/IP the sole protocol.
Create a P2P on the second connection using a X-over cable using NetBEUI, for files and printer sharing only.
Now, I understand I could try it, and risk messing everything up, and have a hard time trying to measure the performance differential, etc., when a more knowledgeable person out there could easily encourage/discourage such endeavour.

I have two computers, a desktop running Win XP SP3 and a laptop running windows Vista UE. Both the machines have independent internet with different ISPs. The Laptop connects to a wireless network. I recently tried to network the two computers by adding additional NIC to my desktop and wiring it through the router. NIC 1 connect to internet through cable and NIC 2 for Home Network wired to the router. I succeeded in networking the Desktop and Laptop and also disabling internet sharing as i dint want 2 ISP on my Desktop. Now the problem is, on my desktop I have my internet connection working through another Lan card and different ISP, so when I'm connected to both the networks ( Internet and Home Network ) the internet seems to work but not the home network. Neither the Laptop or Desktop can connect to each other ( not even see each other ), though they can ping each other and also the Router. Both my NICs are configured with static IP. Home network works fine when I'm not connected to the NIC 1 connection (Internet) on my desktop. I also removed the default gateway from the NIC 2 connected to home network.

Also another thing that i noticed is that if i connect to the NIC 1 then to make my home network work I'll have to not only disable NIC 1 and Enable NIC 2 ..., but also restart my machine...otherwise it wont work.

A:Problem with 2 NICs

You need to do a manual configuration of the direct link.

Configure the direct link's TCP/IP as follows, leave the Internet connections the way they are..

PC #1:
IP address: 192.168.9.1
Subnet Address: 255.255.255.0

PC #2:
IP address: 192.168.9.2
Subnet Address: 255.255.255.0

Leave the Default Gateway and DNS Server addresses blank.

Under Advanced Properties, on the WINS tab, make sure that NETBIOS over TCP/IP is enabled.

Make sure any firewalls are configured to put the 192.168.9.x subnet in the trusted zone.

Finally, you'll have to enable fine/print sharing on the machines and actually share one or more folders or drives.

This should allow Internet requests to go to the ISP connection on each machine, and file/print sharing requests to be handled across the direct link.

Sorry for the somewhat cryptic title. I couldn't really summarize what I'm thinking about doing.

My office network consists of a 2wire home gateway/modem/router and a dlink 10/100 48 port switch with room for a gigabit backbone (although I'm not really considering using it right now.

Here's my dilemma. I have 2 computers that usually pass a lot of info back and forth between (Sometimes in the area of 200-300 gigs). Both computers have integrated 10/100/1000 nics which obviously go down to 100mbits when plugged into the network. So, here are my questions.

1. Does it make sense to add a second nic (like a 3com 905tx) to each pc, plug that nic into the main network and then run a dedicated crossover cable between the 2 computers and put it in the gigabit nic?

2. When I am transferring info between the 2 computers, how do I ensure that the data travels over the gigabit nic and NOT over the regular 10/100 switch?

I appreciate any advice here.
 

A:Considering 2 nics, 1 gigabit

Why not just use the single gigabit connection and put a 5 port gigabit switch in for those two computers? You just plug that switch into a port on the 48 port switch and plug those two machine into it. A $30 switch makes this problem go away.

Hey guys,

Hopefully I'm in the correct section, I have two different ISPs, one PC and two NICs. Ideally what I would like to do is install the two NICs in the PC, connect two cables to the NICs and have 90% up time, eg: if one ISP goes down, it will still be online due to the other NIC installed connected to the other ISP.

Is this possible and do I have to do anything special to get this working?

Thank you
 

A:Windows 7 with 2 NICs

If you don't have 90% up time with one ISP there are serious issues with that service.

I'm pretty sure the answers to those two questions are yes and no, respectively. Unless, of course, you are using a router with each service; that would require you to make sure the routers are using different LAN IP subnets.

For what point? You won't gain any speed, and it's not possible to share a single download stream in any case. The speed of your wired connection is far faster than any ISP connection, you are accomplishing nothing here, even if you managed to get it to work.

I understand that I can go to a site and find a list of NICs that are supposed to be compatible with Vista. This is not what I want. The NIC I had was "certified Vista compatible" but it seems from the boards on the manufacturer's website that this is not uncommon for my card. What I would like to know is: are there any Vista users out there who are NOT having problems with their cards that would like to share brands/ models that are proven by usage to work with Vista?
 

A:Vista-compatible NICs

I've been working fine with Vista Home Premium with the two adapters shown in the attachment. But note that the second one is an integrated one, so you're probably not interested in that one.

Even though my gamble has paid off I don't recommend the Airlink101 unless you get it at a bargain price. Partly because it is USB but also because it is draft 1 'N.' I got lucky--it's working fine with my draft 2 'N' router, connecting consistently at a nominal 270 Mbps.

If you get 'N' make sure it is draft 2. Almost any 'G' adapter with a Vista driver should be fine.

Is there a way to do this?

Hi Moo,

Yes but you would need to create your own application or script that monitors each adapter that you can keep connected while disabling the others, it would require a fair amount of work however.

I am troubleshooting an intermittent issue with a computer that has three Ethernet adapters that aren't working properly. I am out of ideas, so here I am.

The issue began last week with NIC1 showing disabled in Network Connections, and I could not enable it. I tried to repair the connection and received an error that it could not be repaired because TCP is not enabled for the connection. Next I reset the TCP stack and Winsock, and rebooted the computer. After restoring my static IP address settings, NIC1 worked for a while, but then quits working upon the next reboot.

I have tried removing and reinstalling all three adapters, installing the latest Intel drivers, and installing the original drivers.Device Manager shows all three are working, and the Intel Diagnostic utility shows they are all good except NIC1 fails the loopback test. Also tried another cable and switch. When I ping -t 192.168.0.X (another device connected to the switch) I see no activity LED, so it looks like nothing going out on the wire).

I also noticed yesterday when NIC1 is enabled but not working, NIC2 and NIC3 quit working; and when NIC1 decides to work, all three work.

I have two other identical computers that work, and this one did too until this week. Swapping hardware isn't an option yet, as the other two computers are at another location.

Hardware details:
NIC1 & NIC2 are on-board Intel Pro 1000 dual port adapter (82546EB chip)
NIC3 is Intel Pro 1000 MT PCI-X server adapter (82545... Read more

Hi guys,

I'm confused about how to ensure two nics in one pc (Win 8) are configured optimally. My question is actually fairly basic (I think) to you guys who really know networking, but I'm not sure where to start after doing a lot of Google searches.

I saw so many other great responses in this forum that I decided its the one for me!

I simply want to know how to configure, and how to test, that my Dual Gigabyte Nics are set up for maximum LAN bandwidth on my Win8 64 bit PC that is connected directly to a gigabyte capable router (Linksys WRT600N).

One card is a RealTek, one an Intel, if that matters.

I've been confused by the similar terms of;
- Dual Nics
- Nic Teaming
- Link Aggreagtion
- Bonding
- Bridge Connections

I do a lot of large transfers on my LAN, that simple. Be happy to post anything needed to be seen, but I think I just need some clarity through the fog.

Thanks!
 

A:Two Nics, One PC, Mass Confusion

There is no such functionality built-in in Windows 8. You can contact manufacturers of your NICs to see if they have drivers which will enable NIC teaming on those NICs.

Hi!

I have a proxy server in my office, with two NICs

One is connected to the broadband ADSL Modem (not router), and has been given the IP 192.168.1.xxx and the ADSL modem as gateway (192.168.1.1)
The second has a local lan IP, and is connected to the local LAN, and has a leased line router IP as gateway.
The machine is running Windows XP, with Symantec AntiVirus 10.1
I have a regional office with a VPN server running
I can connect to this VPN server from home.
I can connect to this server from office when I transfer the ADSL connection to an office pc with one lan card.
I am unable to establish a connection to the VPN server from the proxy server.
I tried disabling Windows Firewall: but it did not help.
I tried removing the gateway from the local lan NIC, but this did not help either.
I tried adding a route : dest = vpn server IP, mask=vpn server IP, gateway Broadband NIC IP/ADSL Modemlocal IP/Broadband gateway/broadband static IP. Did not work.

I seem to be missing something while establishing a Split Tunnel. There are security issues to be addressed: but only if the VPN connection is made.

No ports/exceptions have been created: since I was able to successfully connect from local machines without doing any such thing.

Request advice: and I would be most disappointed if I learn that it cannot be done.

Request advice
 

A:Solved: VPN on machine with two NICs

Oh: I got the problem.
I have two Broadband connections: one with a wireless router, and one with an ADSL modem direct, so that there is one connection as standby always.
The router requires NATting to allow VPN, which I learnt after many failures and experiments at office and experiments at home.
One experiment at office was to try and setup FreeProxy on the proxyserver, so that I could VPN from lan machines. This port had remained, and maybe was not configured correctly. So FreeProxy may have been listeneing at 1723 and not responding properly.
Neither connection could work on the proxyserver, while the direct modem worked on other machines

I deleted the port, and was able to connect.

I now have some more questions: I am not sure whether I should open a new thread: pl advise.
1) I entered a random (valid) IP address in the 'Use the following IP address') field of the VPN connection. Have I achieved anything? The address I have entered is a Class C address. Should it be a Class A address? Will any address at all prevent bridging between the VPN and the local (my office) LAN, or between the VPN and the VPN server LAN?

Request advice: I intend to use this VPN to replace a P-to-P leased line that I currently use: and to establish inter-office communication.

I see that your log is properly posted, here, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a Malware Removal Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it the logs you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.From this point on the Malware Removal Team should be the only members that you take advice from, until they have verified your log as clean.Please be patient. It may take a while to get a response because the Malware Removal Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the Malware Removal Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another Malware Removal Team member is already assisting you and not open the thread to respond.To avoid confusion, I am closing this topic.

hey guys, i'm getting a cable connection this weekend which is going to be rated at 15Mbps my current connection is at 15Mbps from a DSL Line. basically what i want to do is run them both through my computer which is a core i7 with 2 built in NiCs, i read somewhere that you can bridge the 2 NiCs togther inorder to create a faster connection and or improve your performance. basically all i want to do is double my connection. is this possible? i am quite smart with computers so i'm sure if its going to be hard i can accomplish it. that second NiC is going to waste without a second connection going to it.

A:2 ISPs 2 NiCs 1 Computer

You aren't going to be able to bridge a connection between two different ISP's. Also, if you think about this, you would have 2 NIC's with 2 IP addresses and 2 default gateways. So, unless you plan to set up some pretty elaborate static routes to send out some of your traffic 1 way and the rest of your traffic the other way you really aren't going to benefit from this type of configuration.

Hi

I manage a LAN here at work with 13 computers. I have one that seem's slower than the rest and it should be the fastest other than the server.

It's a DELL PIII 866 w/256MB RDRAM and 40gig HDD also it has 2 nics - one being a 3Com 10/100 and the other is a Intel 82558 10/100. The two nics ar being used one for the internet and the other used for the internal network(LAN).

I just recently installed the max ram in the server which is the exact computer but with 512MB RDRAM.

Where the conputer is slow is gathering info for running a report from the server and then printing it. The mouse gets jittery...like when you move it it's not smooth...it jumps in increments. You just have to give up using the computer when it's working.

Any help in this matter would be greatly appreciated.

Cheers

Hey all,

Here is my situation: My university throttles traffic to 350kbps for each user, but I only download at off-peak times and think I should get more out of the connection. I would like to somehow bond my two ethernet NICs so that I can increase throughput on the network. If someone could get me started in the right direction, or has experience doing something like this I'd appreciate the help. Basically, I want my Internet connection to be split across two NICs to increase throughput to about 700kbps.

I have an A7N8X deluxe motherboard which has an onboard nvidia lan controller and also a 3com lan controller. I've been using the nvidia controller to connect to the internet via cable modem and have had no problems until now. I went on vacation for a week and when I returned home and turned on my computer the network connection icon on the system tray states that a network cable is unplugged. I checked and rechecked all connections...no problem found. Tried a different cable modem.. still says a network cable is unplugged. Tried using the 3com adapter with same results. Reinstalled drivers...still no help. I then plugged in my old pci 3com nic and connected no problem. Not sure if it's a hardware problem such as my motherboard or just a problem with settings.

Hi Guys,
I want to connect 2 small LANs together one a 10Base2 and the other a 10BaseT network. They are both using TCP/IP with addresses in the range 10.0.0.x and subnet mask 255.255.255.0 I understand that it is possible to connect both by having 2 NICs in one PC one connected to the 10Base2 and the other connected to the 10BaseT network.
I have experimented but the only machine that can see both networks was the PC with the 2 NICs. I have used different IP addresses and the same IP addresses on the 2 NICs with no further success.
Both networks are using Windows98 SE.
All help would be appreciated
 

A:Connecting 2 LANS with 2 NICs in a PC

Windows 9x does not reliably support multiple NICs. Neither does it support bridging, which is what you are trying to do by joining together two pieces of the same subnet.

Your best bet for making this work is to buy a 10Base-2 to 10Base-T Transceiver, and hook your Thinnet string up to the hub on the Twisted Pair network.

Can someone tell me what is the proper setup for 2 NIC cards in 1 PC? My office is going to DSL and all PCs will use NICs connected to a router. However, 2 of the PCs are linked together via NIC cards and a 5 port hub. They need to stay together but also need to be able to access the internet. Currently, they connect together via the NIC and hub, and access the internet via 56k modem.

Can I just install the new NIC cards and configure them as I would any other NIC card? Or is there some protocol I need to insert to keep them distinct.

I should mention not all the PCs are the same. All are Pentiums but some are Dells and others are no-name brands running PIIs.

Thanks to anyone who can help with this.
 

A:Proper setup of 2 NICs in one PC

Is there an uplink port on the hub. If so you can leave them connected just use the DSL line in the uplink port.

Workstation running Win7 Pro has 2 NICs.  We bridged the two NICs together (WAN miniport bridge) and connected them to the
same subnet on a switch.  We thought this would act as bonding/teaming and provide failover protection, but we now realize teaming requires software from the NIC manufacturer, Intel.
Wireshark capture seems to see double transmission from the workstation, flagging every other packet from the workstation IP as a suspected retransmission.
Does bridging two NICs to the same LAN result in packets flowing out both ports simultaneously, or cause some sort of routing loop?  We wonder if the server is receiving double data from the workstation and getting confused.

I have a small network setup at home, with a server, 2 workstations, and an 8 port router. In addition to my 100mbs NICs, I have placed an additional GIG nic in one workstation and the server, using a Xover cable to connect them and bypassing the router, hoping to achieve a higher transfer rate between the 2. I want to use the 10/100 for internet traffic, going through my router, and isolate the GIG nic for transfer and connection to the server/domain. Can I do this.and how?

Hi,

I'm at school in the dorms and hubs are not allowed. I'm often helping set-up / repair comps and also I have a separate laptop and the wireless signal in the dorm is very poor. I currently have an ASUS P4C800-E Deluxe with the built on gigabit lan. I installed my old 10/100 realtek adapter in it as well. I want to hook the school's iNet up to that and then run the realtek adapter to a second PC so that has internet. Is this possible?

We don't want to use a router because that will block accessing shares via the school's network as well as mess up connecting to multiplayer games. Since I only am usually using one other comp I figured the 2 NIC idea was the best.

I've heard a switch should work, however, if I don't have to shell out an extra 20 bucks I don't really want to. I have spare NICs and cable at school already.

All comps run winXP Pro. If this works I'm also debating throwing in a 3rd NIC to repeat the process and allow for a third computer to be hooked up.

Thanks for all help in advance. I consider myself average with networking and also creative so feel free to spit out ideas that may help or correct any wrong assumptions I may have.

A:Sharing iNet with 2 NICs ...

2nd NIC, no problem, setup internet sharing, make sure XP's firewall doesn't get in the way, use a cross over cable to connect the two computers together.

Caveats: If you've got the extra NICs, I'd suggest not using the built in NIC. I don't know about that particular motherboard, but most built in NICs steal processing power from the CPU to run. This is usually un-noticeable if you're on a Cable modem, DSL or Dialup network, but at 10/100/1000 Mbps, it will suck the life out of that CPU (ie. it will be working really hard during large file transfers, and the transfers will be very slow, or may die before they're done. It's ugly).

Also, 3 NICs will NOT work. At least not without a LOT of pain. NATing with 3 connections is so complicated, CISCO has had many revisions of their IOS that doesn't do it right. Maybe it's possible to configure correctly under a MS OS, but I wouldn't want to waste several months of my life trying to figure it out. If you want to connect more computers, put a switch on NIC #2, and connect everyone else up to the switch.

I have a PC with 2 network cards, one wired, one wireless.

When I try to connect to the internet with this pc I get an error that states the page cannot be found. Apparently it is only looking for the internet on the wireless nic and not the wired one where the internet is.

Can someone help me fix this problem?

A:2 NICs & Internet Access

What you need to do is point the default gateway out the right network. You probably have two 0.0.0.0 routes pointing out both interfaces at the same cost. Unfortunately the OS picked the wrong one to use as it's actual default gateway.

One of the simplest ways to fix this is to increase the default metric of your wireless card to something higher than the default metric of your wired connection. (Higher metrics mean less desirable link.)

Under the network card's TCP/IP properties, click advanced. At the bottom will be the interface metric; most likely 1. Change that to, say, 3. You may need to disconnect and reconnect the networks, or reboot will work too. But that should fix the problem.
