I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

I was working on a XP SP2 computer yesterday and was unable to establish a valid IP address. I was able to get a valid IP address with another XP computer so I know it's not the service itself but the computer. I tried running winsock fix, removed Norton Internet Security to make sure it wasn't creating any conflicts, installed a Usb-to-Ethernet adapter--I even restored the computer to a month prior to no avail. The weird thing is, I'm able to get the initial local IP of the cable modem itself which is a good sign but when it tries to release the local IP for one assigned by the DHCP server, I get all 0's or a 169 IP. Any ideas on what is happening?

Hi -
I have an older IBM Thinkpad (365X) with Win95B. I have a Xircom Ethernet/56K Modem PCMCIA card, which I know works, since I can use it in other machines that I have.

I have DSL with a netgear router that has a DHCP server, which I also know works, since I'm using it to send this message.

I have reinstalled the adapter, all of the protocols, the client software, and the physical card in every way I can imagine, and cannot seem to get the machine to recognize the network. I checked the MS support site, and downloaded the Winsock2 patch. Didn't help. Still getting message about not being able to obain an IP address from the DHCP server. Most frustrating.

When I ping my own machine, I get an response with no lost packets. When I ping any of the 3 other machines on my local network I get a "request timed out" response.

If I hard code the IP address into the machine, I still cannot see any of the other machines.

I'm about ready to give up, so if anyone has any other ideas, please let me know.

Thanks

Hello Everyone,

We our setting up a Training Company to assist unemployed IT people in the Silicon Valley area of California. Our group is very small and having a hard time even getting our network here started. Here is the problem: We have Windows 2003 Server Enterprise 180-day usage disc (from a book we bought to learn). We have 5 static IP addresses leased from DSL carrier. They are for example: 65.123.141.10 thru 65.123.141.14 with a gateway of 65.123.141.9 [these are only IP numbers used for example to prevent hacking] my subnet mask is 255.255.255.248 We tried and tried for 2 weeks now and still can not get the complete network to work. We need: Step1.) The server to be secure with a firewall (but willing to forgo that and add later) Step2.) the server to issue Ip addresses from a pool of 192.168.0.10 thru 12 to 3 workstations running XP(we decided to make the server 192.168.0.5, subnet mask is 255.255.255.0 and gateway 192.168.0.1 Step3.) Have access to the internet on all workstations and the server too. All we have succeeded to do is get the dhcp to issue out addressses to the workstations and even that i think we got lucky. We think the problem is somewhere you need to tell the (maybe iprouting?) setup that the Public ip address is the 65.123.141.10 and gateway, subnet info and to route to the server PRIVATE ip address 192.168.0.5

I just got a new router set up in my house (Trendnet TW100-S4W1CA) to replace my dying one.

It's hooked to a Linksys WAP54G which in turn provides wireless (in theory) to my and my roommate's Xboxes downstairs.

However, neither of the Xboxes can obtain an IP address automatically.

DHCP *is* enabled on the router and my laptop can connect to the wireless just fine using DHCP. My desktop wired connection works perfectly as well. The consoles are just being special snowflakes apparently.

Router IP/subnet: 192.168.1.1 / 255.255.254.0
WAP IP/subnet: 192.169.1.103 / 255.255.254.0

I have a new Vista PC (SP1) connected to a Draytek Vigor 2600gi (with the last available firmware).

When I set the IP address to static, I can ping the router, edit the settings etc. However, if I set the IP to obtain automatically, the adapter gets assigned a 169.254.x.x address.

DHCP on the router IS working - if I connect a Windows XP PC to it, it gets given an IP with no problems.

I have tried disabling IPv6, and I have tried booting in Safe Mode with Networking - neither worked.

I have removed Norton Internet Security which was installed as a trial.

I have uninstalled the driver for the Ethernet Adapter and rebooted to let Windows reinstall it, and I haev since installed the latest Vista compatible driver from the manufacturer.

None of these are working.

router B handles wired and wireless internet ( I have it MAC enable, so ppl won't be able to access my wireless network from outside)

how should I setup so PS3 can access movies from computers behind router B ?

EDIT: I tried to make them within the same subnet

router A : 192.168.0.254 (DHCP 65-99)
router B : 192.168.0.1 (DHCP 100-120)

when I connect router A with B by connect ethernet cable by LAN, Router A is able to ping a computer behind router A, but the computer can't ping router A.

Hi folks,

As I've said in the title, I'm looking to make a network with two routers but only having DHCP enabled on the secondary router.

Before I go any further I must ask: I have an Arris GT840A (sigh) as the primary ISP required modem. I'm currently connecting via wifi and sometimes have pings to the router coming back in the 1 - 20ms range for extended periods and it's decent. Other times I get a huge range of different ping times, often in the 300ms - 6,000ms range and sometimes even dropped.

Is disabling the DHCP server on the modem and relegating all local networking duties to my WRT54GV2 likely to alleviate this problem, or does this simply boil down to I'm screwed because I have to use this Arris modem?

Moving on with the primary question, here is my current setup:

Router 1: Arris GT840A
WAN IP: Dynamic / ISP assigned
LAN IP: 192.168.0.1
DHCP: Enabled
192.168.0.2 - 50

Router 2: WRT54GV2 (Connected to router 1 via WAN port)
WAN IP: 192.168.0.51
LAN IP: 192.168.1.1
DHCP: Enabled
192.168.1.2 - 50

With my current setup I have been able to ping both router 1 and 2 via wifi, but I have not been able to ping or connect to the internet at large. I have read a couple of different how-to's and other forum answers and feel like this is how I'm supposed to be setting it up, but it's still not working. Something that concerns me about this attempted setup is that it still is using DHCP from the Arris modem / router, and I'm r... Read more

Hello. I just moved to Auckland, NZ from the USA to go to school at the university here, and am having a problem connecting to the internet in the university residence hall in which I am living.
Wifi is not available in the residence halls, so we need to use an Ethernet cable. When I plug in my computer, the network adapter icon says “Identifying...” for a while then settles on “Unidentified Network” with no internet access, the IP is 169.x.x.x
When I try to release and renew the IP, it says “unable to contact your DHCP server, request has timed out"
I've tried multiple Ethernet cables, both brand new.
I tried connecting to a port in a friend's room in the same building, and even in a classroom on campus, and both had the same result.
Naturally after all that I assumed my NIC somehow died overnight while I traveled here, so I went to a computer repair shop expecting to have some hardware replaced, but we plugged it in there and it worked immediately so they weren't sure what to tell me.
I've gone through pages of old threads at this forum and others like it, trying solutions but having no luck.

Apologize if this was already discussed before. I recently moved to a new apartment and have been having a strange problem with my Comcast broadband connection. I did not have this problem at a place I stayed before.

My Comcast Motorola modem is connected to a D-Link wireless router. I have cloned my laptop's MAC address to the D-link router. In the event of a power failure, in order for me to connect to the Internet via the wireless router, I must first connect my laptop to the modem over RJ-45, restart the laptop and let the modem assign the Comcast WAN IP address to the laptop, disconnect the RJ-45, and then connect the cable between the modem and the wireless router. If I do this then Comcast is able to assign a WAN IP over DHCP to the wireless router, otherwise not.

I also noticed that the WAN DHCP is a two stage process - first Comcast assigns a temporary IP for a few seconds and then followed by a "permanent" IP address. I would off course like to have my router obtain the WAN IP address directly from Comcast without having to plug the laptop everytime there is a power recycle.

Has anyone had a similar experience?
Thanks

When logging onto the company network via a RAS server, the DHCP active leases is not being updated with the IP address assigned to me. This is the case both when the RAS server is configured to give an IP address from a fixed pool, or when configured to obtain IP address from DHCP. As a result, I'm experiencing problems if an existing lan device has an IP address assigned and the dialed in device grabs that address. Whats going on ?
 

A:{Solved} - DHCP active leases not being updated when dialing into network via RAS server

Greetings

There should be a clear distinction between the IP adresses available for the network, and those available for the Dial up users. Do not make them part of the same IP group.

The reason is that Dial-up IP addresses should have a lease time of a few hours, and the LAN lease time should be that of a few days. This is obviously not compatible, so they need to be seperate.

Hope this helps

I have a problem with configuring network cards

WIFI comes nicely with DHCP pool 192.168.0 .*
but

I have a virtual network adapter "Microsoft Loopback Adapter"
in it I have to have a static IP address 2.0.0.5
and set it manually (IPv4)

the problem is that the WiFi card is still changing my IP address of the virtual card

how to prevent it?

I wanted to wifi card automatically collects the IP address
but did not interfere in the virtual adapter's IP

A:Wifi DHCP - the second network card on a fixed IP

I quote (from ):






Quote:
Microsoft Loopback Adapter is a dummy network card, no hardware is involved. It is used as a testing tool for a virtual network environment where network access is not available. Also, you must use the Loopback adapter if there are conflicts with a network adapter or with a network adapter driver. You can bind network clients, protocols, and other network configuration items to the Loopback adapter, and you can install the network adapter driver or network adapter later while retaining the network configuration information.


Given that, there is no way your wi-fi card can "change" the IP address of your fake network adapter. If you set a static IP for ANY adapter, it WILL stay that way, regardless if one adapter is set to release and renew based on DHCP and one is not.

I even tried it myself. I installed the loopback adapter, set an IP and all that for it, released ALL DHCP'd IPs and renewed them. the static IP for the loopback adapter didn't change.

Take a look at your settings again, make sure you didn't miss something.

Having trouble with my Windows 7 Ultimate (64-bit) wired LAN connection. Yesterday evening everything was fine, I was connected and doing some remote work into the office - I was playing with OpenVPN connections. I left the machine for a few hours logged on, came back and now the NIC appears dead.

2. Tested the internal NIC by pinging 127.0.0.1, loopback successful.

Hello All, My company has been buying the M910Z systems since last year and I have noticed that the NIC card on these things will just randomly not pick up an IP address via DHCP when the PC is first powered on or when a network cable is unplugged. This doesnt happen everytime, but there are instances when the PCs go to sleep and the user is unable to connect back to the network due to the PC dropping the network connection. To resolve the issue, i have to either shut the PC down and then boot it back up or go into the control panel, diable/enable the NIC card in hopes for it to grab an IP. Is there a fix to this issue because im assuming its either a BIOS or NIC driver issue because I have isolated the issue down to these PCs and i wanted to see if the community could help me out here.

I have a problem with my pc randomly locking up and having to be rebooted. I believe it has to do with the wireless card accessing my network, but I can’t figure out how to troubleshoot it. (If this is the wrong forum, please let me know!)

I have a desktop, two laptops, and a printer on a wireless network. All of them have been working fine. Then, about a month ago, I loaded a new game on my desktop, which worked entirely fine for roughly three weeks. Then last week, I tried setting up a server in the game. On my first attempt, it locked up my pc at the setup server stage, and I had to reboot. On my second attempt, I tried a slightly different configuration, and it created a local server and worked just fine.

Everything seemed okay for a couple of days, and then the game started to lag after a few minutes of play. After two or three more rounds of play, the lag was then accompanied by the pc locking up. Couldn't figure out why, so I stopped playing it.

Within a day or two, my desktop would randomly freeze without warning, with no clear connection to any specific application or time of day. This has continued to today. Sometimes the lock up is preceded by erratic behavior, such as the wireless keyboard freezing up though the companion wireless mouse will work (or vice versa) and an occasional USB connecting-then-disconnecting sound, though nothing had been touched. Sometimes the lock up is for 10 seconds or so. Most of the time, though, there are no warnings, and it ... Read more

I'm running a simple network at home with a Linksys BEFSR41 router. I have two computers hooked up wired and a wireless router acting like an access point that I use for my laptop occasionally. Until this weekend I've been having no problems but I shut down the computers due to weather and now one of them is not able to communicate with any others on the network. The problem computer will get an address supplied to it by the router (DHCP server) but once it has it I cannot get any other connectivity. Of course this is hindering internet access on this computer. I can ping the loopback and assigned IP addresses w/o problems but when I ping the default gateway (router) and/or the other computer I get "Request timed out." I initially thought it was the NIC so I bought another one but still get the same issue. I've moved the cards to different PCI slots but no luck. I tested the cable running from the computer and the router but found no problems. I even tried resetting the TCP/IP stack but still didn't work. The computer in question is running WinXP SP2 with the original NIC being a Linksys LNE100TX and the new one being a D-Link DFE-530TX+.

Any clues on this? If more info is needed let me know--it's been a while since I've posted. Thanks in advance.

QUESTION #1:
Is it better to use Win2000 Server DHCP or DHCP from my Netgear wireless router?

#1 BACKGROUND:
I am currently in the process of setting up a Win2000 server on my home network which consists of four other 2000/XP machines.
The server is going to be configured as a domain controller and will utilize the Active Directory.

Should I use the Win2000 Server DHCP or stick with my wireless router as the DHCP server? What are the advantages/disadvantages to both and which would be easier to maintain.

QUESTION #2
Is a 550mhz PIII with 256MB RAM fast enough to make a good home server running Win2000 server?

BACKGROUND #2
The server is going to have (2) 120GB Western Digital 7200rpm drives with 8MB cache for storage and a single 60GB Western Digital 7200rpm drive for the OS and few other applications.

The server's primary function is to serve as a media server with an approaching 10GB of MP3 and music video files which is continually going to grow. Disk contention is at a minimum since there are only four PC's on the network. There will also be a lot of digital photos stored on the server and will also serve as a place to perform backups from the other four networked PC's.
 

A:Win2000 Server DHCP or Router DHCP?

We have a similar setup in our office using Small Business Server, a public IP coming into our router with DHCP turned on, connected to a NIC in the internal DHCP server (which is also running ISA). A second NIC in the server bridges to the internal hub to provide DHCP services to the clients. This way we control port filtering in 2 places and with 2 levels of NAT taking place we feel secure. It may be overkill but we're concerned that EVERYONE is trying to hack into ISA and DHCP servers connected directly to public IP that this setup provides an added level of security.

IP Network: Dhcp server works fine. (CISCO ROUTER)

Windows 200o servers, Windows 2000 clients (up to dated, sp4, rollup1 etc) IS6sp1

Some pc's with IP dhcp , works ok
Some pc's with fixed IP, works ok

After changing fixed IP on a client to dhcp-IP, the client can not find the DHCP server.
change back to fixed IP, PC works fine again.

DHP server and other DHCP clients still working fine

I'm messing around with W2K Server at home and can't seem to get it connected through my cable modem to my ISP's DHCP server. I know the cable and connection are good because it works on my W2K Pro workstation. I've tried ipconfig /renew but that's when the error occurs that it can't find DHCP. I can successfully ping the loopback address. The NIC is set to use DHCP.

Since I'm just becoming familiar with Server I'm sure there's something I'm not configuring properly. Suggestions?

Thanks.

Hello, 
 
I have been battling this problem for over a month now. 
 
I lose connection to the internet at random times.  Eventually, I figured out that under TCP/IPv4 Properties, "Obtain DNS server address automatically" is being changed to "User the following DNS server addresses", and then an IP address would be specified for "Preferred DNS server".  When I undo this change and choose "obtain DNS server address automatically", I regain my internet connection.  
 
I tried checking these settings at random times when there is no problem with my internet connection.  Most of the time the setting is unchanged.  But sometimes a Preferred DNS server is specified.  It feels like at those times, my internet speed is slower than usual, but I can't be sure.
 
I have Windows 7.  I tried scanning my computer with Microsoft Security Essentials, but it didn't find anything.
 
When I used HijackThis.  I attempted to fix some entries that didn't look right.  However, when I scan my pc using HijackThis again, it displays all of the entries that it said it fixed the last time. In addition, when I tried clicking "analyze this" in HijackThis, I received an error message that I wasn't connected to the internet (even though I could load websites).
 
You can imagine how grateful I would be if I were to receive any help with this nightmare.
 
Thank you for considering this problem and for reading my message.

I was trying to use tftp32d to pxe boot machines however, I couldn't get the DHCP server that is built into that program to work and eventually got angry and gave up. When I had some more patience, I started trying it again and it worked immediately without any settings changed.

The reason for my post is because it stopped working again. I can't figure it out and it's driving me nuts. Could this be an issue with the setting where you can select which network your own for example work, home or public location?

Hi Guys,

Was wondering, I'm setting up a VPN on a DELL Windows 2000 Server and as I am walking through the wizard setup, the part where it ask what NIC card I want to use for Internet access, this system has only one? So when I select it Windows comes up saying "you have selected the last remaining network card........" or something to that effect...

I am wondering, must there be two NIC cards in the computer before I can setup a VPN?? or by selecting the only one, that I am limiting my VPN connection??

THanks!

TL-WR340G problem : router cannot obtain parameters ("obtaining parameters" undefinitely)

Minutes ago I had a router model TL-WR340G working perfectly until I noticed there was no connection at all.
The interface Status screen shows "obtaining network parameters " undefinitely.
First I checked all physical connections between router , modem and computer and it seemed all was fine.
Then I connected the modem directly to the computer LAN port and had no trouble in getting a connection.
Reconnecting the router to the modem I reset the router and reconfigured it but it does not obtain the WAN parameters.
I find it very odd as nothing was changed , as explained it was working normally and the next second it was not. Any suggestions ?

Right now I have my server connected to a router and the router does the dhcp for me. I am thinking of putting a second nic in the server and using it for dhcp. If I have computers in the house that are not a part of my domain will I still be able to get online with them if they are connected to my switch? I guess to paraphrase myself I am asking can you use a server to route and not have everyone connected to the server in your domain?
 

A:Server DHCP or No

I'm not sure what DHCP has to do with routing... Are you trying to break your network into subnets?

You wouldn't need a second NIC to move DHCP to your server. If you want to move DHCP from your router to your server, just set up a new DHCP scope on the server and that's all that's required. Clients do not have to be part of the domain to get an address from a DHCP server.

RELEVANCY SCORE 51.2

Here is my current configuration:

We have 7MB/768K DSL Business dynamic IP connection.
Anywhere from 10-20 simultaneous users.
One Cisco 30 port switch feeding into one Linksys wireless router to provide local IP addresses to all the users for the one IP address to the world.

It seems to me we have a huge bottleneck at the wireless router but we need it for the DHCP server in that router.

Are there any low cost solutions that would provide faster performance for the users?
 

A:DHCP Server (Do I need one?)

Hi skibizkit, and welcome to TSG.

skibizkit said:

... provide local IP addresses to all the users for the one IP address to the world.

It seems to me we have a huge bottleneck at the wireless router but we need it for the DHCP server in that router.Click to expand...

Sharing a single Public (world) IP address with multiple Private (local) IP addresses will require some type of router that supports NAT (Network Address Translation). Running a DHCP server on the router should only add a small amount of local bandwidth usage when a computer first connects to the router and gets assigned its private IP address by the DHCP server. The DHCP server is then out of the picture until another computer comes on line or the DHCP lease time (could be up several days) expires for each computer.

Is the speed bottleneck related to accessing the Internet through the DSL connection or exchanging data between computers (and servers) on the same local network?

Hi,

So I have an Acer Aspire One notebook and I recently got a virus on it due to something that was going round on Facebook... Anyway, I tried everything I could to try and get rid of it, but then came to realise my only solution would be to restore my computer to factory settings.

I did this and now I can't get it to connect to the internet. It recognises the network and connects to the network, just with no internet access as it says that the wireless network adapter can't obtain an IP address... I have googled the problem and seen lots of posts about it, but they are all too technical for me to understand how to resolve it.

I am a 23 year old and have mild learning difficulties. I can understand what I need to do if it is explained in as simple terms as possible, but I don't understand a lot of the terminology.

It has always connected to the internet absolutely fine so I am not sure what the problem is.

I would really appreciate it if someone could offer me some help with resolving my issue.

Thanks in advance.
