Gateway is receiving more network traffic than it can process. A portion of the network traffic is not analyzed.

Q: Gateway is receiving more network traffic than it can process. A portion of the network traffic is not analyzed.

I keep getting this alert despite the amount of resources that I add to my Gateway.
Our DC and Gateway are running virtually in VMware. Distributed Virtual Switches are not an option so I have to resort to configuring Promiscuous Port Group.
I configured a Promiscuous Port Group on the same Virtual Switch that the DC (and the rest of our servers) is connected , and assigned it the same VLAN ID as the DC.
ATA is capturing and reporting traffic but I continually receive an alert for some network traffic is not being analyzed. I have thrown double the resources at our Gateway's
than what the sizing tool identified, and still receive this alert. At this point I have 24GB of RAM and 10 Cores allocated to my Gateway which is only capturing reporting on 1 DC. At this point I am about ready to scrap ATA because of how resource
intense it is.
Any ideas or suggestions? Does it sound like I have the Promiscuous Port Group configured correctly, or is it possible that I am capturing ALL traffic for the VLAN assigned?

Preferred Solution: Gateway is receiving more network traffic than it can process. A portion of the network traffic is not analyzed.

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)


Hi guys,
We have the latest ATA (version 1.7.5757.57477) installed in our environment.
I've configured the DCs Port Mirroring as the Source and the ATA Gateway as the Destination.
The ATA Gateway as well as the DC are both running on the same Hyper-V Host (as recommended in order to mirror all the traffic from DCs to the ATA Gateway).
Every few minutes I get the following message:

Gateway not receiving network traffic:
The Gateway "GatewayName" is not receiving mirrored network traffic. This might indicate that port mirroring from the Domain Controllers to Gateway "GatewayName" is mis-configured.

Is there some additional steps that I've missed?

Installed ATA with no issues or errors. I've got a physical server running ATA Center and a separate physical server running ATA Gateway, and my Domain Controller is a physical server on the same network and VLAN. 
I have two ports on my switch connected from the Domain Controller to the switch, and two ports on my ATA Gateway connected to the same switch. 
For simplicity, port 1 and 2 on the switch are connected to the Domain Controller, port 3 and 4 are connected to the ATA Gateway.
Port 1 is set as a monitored port and port 3 a mirrored port in Mirror Group ID 1 on the switch.
Port 2 is set as a monitored port and port 4 a mirrored port in Mirror Group ID 2 on the switch.
I have confirmed with NetMon that bi-directional traffic can be seen between the Domain Controller and the Gateway on one of the NICs, but not on the other. I think this is due to there not actually being any traffic down the other as it is for redundancy
I believe.
The Gateway has successfully discovered the domain, DCs, users, computers etc, but I am not seeing anything in the timeline as yet (I realise I may need to wait a while for some actual events). 
I also keep getting a high error: "Gateway not receiving network traffic", saying that the Gateway is not receiving mirrored traffic every half an hour or so. Could this be the interface that is connected to the redundancy port causing the error?
Since it is possible that no traffic is actually going down that port? ... Read more

Is there a good network traffic/broadband monitor that actually keeps track of ALL (really ALL) traffic in a network?
I have used quite a few (eg, Ethereal, ntop, network probe) but all of them kinda keep track of only traffic that is coming in and out of the PC they are run from.

I need one that really tracks every single transaction that goes on in the network, including PCs talking to PCs, PCs talking to servers, servers talking to PCs, PCs talking to printers, etc.

Would help a great deal if they are FREE too!

Anyone know of any good ones?

Dropped port mirrored network traffic
<monitoring-alert-loader part="description">ATA Gateway, <Domain Controller>, is receiving more network traffic than it can process. A portion of the network traffic is being dropped.</monitoring-alert-loader>

Installed ATA a couple of weeks and I'm getting a health event like the one above one or more times a day. One of the events coincides with the backup job, so it makes sense that network load would be high at that time (around 9pm) However I'm also getting
notifications during the day which does not make sense to me.
My domain controllers are 2008R2 running on Hyper-V. Each with 4 vCPU and 8GB memory. Total of 8 DCs across three sites.
Memory usage for the microsoft.tri.gateway.exe process at the time of the event is 3GB, total memory usage around 5.5GB which leaves 2.5GB of free memory. CPU levels out at 24-26% which makes me believe the application is actually single threaded and only
using up one of the available vCPUs.
Anyone else seeing this behavior on their environment?

We recently implemented ATA with the Lightweight Gateway model across about a dozen Domain Controllers this past weekend. Half of the DCs are physical and the other half are VMWare VMs. We sized both the ATA Center and the Domain Controllers based off the
packet per/sec recommendations and took the average. For reasons unknown, all of our VMs are alerting with the "Dropped port mirrored network traffic"
alert across all of the VMs, but not one of the physicals has alerted.
Has anyone else experienced this behavior and resolved it successfully? It appears to be a false-positive, but I would have to hit the "ignore me" button and not see it when valid.

I'm not sure if I'm trying to do the impossible but I'll explain the situation.

I have this roommate that is excessively consuming the majority of the networks bandwidth. I've blocked all service ports except for 443, 80, and a few other ones used for every day task. The problem is that he is still consuming a ton of bandwidth, I'm guessing by streaming or downloading through HTTP.

I have *two* WGR614v10 router, and a Realtek PCIe LAN card controller at my disposal. I attempted to set QoS settings on what we will call Base Router. That did not seem to do the trick because router QoS only blocks ports and slows upload speed. Since that did not work I hid the SSID/MAC filtered connections to the Base Router and then connected my computer to the Base Router and rebroadcasted the signal using a Secondary Router using a shared connection, which I gave him access to. The point of this was an attempt to control bandwidth through the Realtek LAN card; I am not having any luck with this though. I've set the adapter to 10Mbps at half duplex already.

Does anyone have any suggestions on what I can look into for limiting bandwidth? I want him to have Internet but not abuse it like he's doing because that is not what we agreed upon.

A:How to limit network traffic speeds with a network card?

If you want to solve the issue using your existing equipment, you can try dd-wrt on one WGR614v10. See this thread (DD-WRT Forum :: View topic - WGR614v10 Support - Jump to post 9) which claims that there is a dd-wrt flash for WNR1000v3 which works on WGR614v10. Then look a thread like this (DD-WRT Forum :: View topic - Steps for Permanently limit Bandwidth of a PC using DD-WRT ?) to setup the limits. You can start a new thread in those forums if you want someone to walk you thru the steps.

Or you can just buy a router/access point that has a bandwidth limiting feature for each SSID that it broadcasts.

I use NetMeter to monitor in and outbound traffic to my computer, and starting a coupple of months ago, every once and a while, a series of a thousand or so 2.25 to 3Mb/s upload spikes start, amounting for almost 1Gb per day!!!!!

the spikes occur every 20 seconds, like clockwork.

i'll post a screenshot from netmeter next time it happens.

the odd thing is, no antivirus i've tried has found anything! same goes for antispyware!

whenever i start deleteing processes from the process list, it stops, then comes back after a coupple of minutes! also, if i am running on wifi, plug in my network cable, wait for it to connect, and disable wifi, the pulses subside for a bit, then come back!

i'm concerned because of the incredible ammount of data involved, and, it seems to have been increasing iver the past month.

Luckily, all the important data on my machine is encrypted, but, if the spikes are a data transfer, encryption won't mean $#!7.

any ideas?

Can anyone walk me through trying to fix my networking issue? Is that allowed in this section?

If so, I've got a computer connected to our network, and it's able to access all the other computers on the network, but trying to access it from the server and I get nothing. Even trying to ping it from the command prompt it times out. However, pinging the server from the computer it kicks back immediately. It's not a firewall issue because I've turned it off and still cannot connect to it from the server. I recently had to remove some scareware from this computer, and that's when the networking issue started.

Any ideas?

Thank You,


A:Traffic on the Network

A workgroup won't really help with router traffic. It's just a logical arrangement for the computers.

I don't honestly know enough to say whether a bridge would be better, but I would think a switch would be more cost effective.

Hello, so we have Comcast internet and have recently been hit with a Data cap of 1 TB per month. Anyways we have never come close to 1 TB, 615 GB at most which even that I think is high for only really 2 people that use the internet in the household while 3 people use the internet one of them uses it rarely and does no Netflix or youtube or anything of the sort. Anyways this month Comcast's data meter claims we've used over 110% of our data and show us at like 1140+ some GB's used already which for 2 people and sometimes 3 is really not accurate in my opinion even though they claim it's accurate. So even though we've never gone over before and never even come close to our cap this month it's showing and telling us we have/our. So to get to the point I want to know if there is a good way for me to monitor and easily see what's on my network and what's using all the bandwidth that Comcast is claiming I we are using so I can compare it vs there own meter which I feel is very inaccurate and if not then see if something happened that for some reason caused this huge spike in data usage. I have called them but they were no real help and just kept explaining/asking me if I know we have a cap and or if I know that playing video games or watching Netflix uses data which I do I mean I am not stupid, I even used Comcast's own data usage thing where I inputted how many hours of streaming video a day or video game playing.

if I were to share a secured dsl wifi connection with someone else.. would it be possible for others on the network to sniff or through any other possible means available get access to passwords or content I browse???

A:Traffic Safety on a network

It is possible to have access to a DSL system via a router without sharing local files, after all this is what happens at every coffee shop with free Wifi access

The "trick" is to make sure that the network is set to private which will disable the file and printer sharing and network discovery (by default, unless this has been edited).

If you have an existing multiple user system where sharing is already set-up, and wish to add an extra system with just internet access you should, dependent on your router, be able to enable guest access to the net but with no sharing access, (this may be the best option as the security would be managed in the Router, and i's hardware firewall/NAT)

One thing to ensure whichever way you go is to use strong passwords on all systems and especially the router, (both the wireless security and the router admin account)

I have a client with a small workgroup network. There are 6 workstations all running Windows 98 SE, and they are using a PC running Windows XP as a file server.

They have a problem with a certain piece of software sticking at random intervals, it will stop responding for a certain amount of time, sometimes a few seconds and other times 10 minutes and then it will suddenly free up and start working again, there is no pattern to it and I cant find any way of replicating the problem. As far as I can tell its down to network bandwidth being eaten up by something on the network but would like to run some software to prove this correct, and obviously determain which machine is using all the bandwidth.

I would like to put some software on there network to monitor the amount of traffic being produced across the network by each workstation, and was wondering if anybody had any recomendations?



A:Network Traffic Monitoring

What kind of software is this?
Is it server based and accessed by the clients?

I've got a client who has his office in his home. Unfortunately, his two teenaged sons are also on the network with their own PC's. Last month there was over 200 GB's of traffic through the ISP.

Of course, the owner thinks the kids are the best thing since sliced bread, so he's pointing the finger at me. Soooo...I need to not only capture packets as they route through the server, but I need to determine the nature of the packets either via protocol or better yet application, and it would be nice to determine the IP they're coming from. I'm sure they're doing extensive file sharing, but other than getting onto their PC's I can't prove it.

Let me just explain the situation before asking my question. In South Africa on the broadband lines, which our fastest is only half as fast as the slowest offered elsewhere in the world, we now have the added pleasure of hard capping. Meaning that when we hit our cap limit of 3Gb of data we get cut off from the net. No browsing of even local sites like it used to be. Lately on our account we've been getting downloads of around 144Mb a day. We're not on long enough between jobs to use that about of data transfer. I've been monitoring my bandwidth usage and i've yet to use 4Mb today.

So what i'm wanting to know is this. All our computers connect to the net through our server. I'm wanting a program to put on there to monitor who goes where, and how much they're downloading. The amount of data they're using is the most important part, we don't really mind where they're looking. There's only four of us so it's quite transparent what's happening around here.

Does anyone know of a decent package that can do this? Preferably something that won't break the bank.

First off, I am not sure if this is where this post goes. This seems to be the best thread since my question sort of falls in the security side of things.

OK, say I have a network setup at my house. Someone brings over a laptop and plugs it into my network. Would it be possible to tell what program they are running on their computer from one of my computers without accessing their computer? Say, the program requires HTTPS port to remain open and the program runs non-stop while the computer is plugged in. Is there a way to figure out what program they are running or what website they are connecting to is?

A:Network Traffic Question.

Yes and no. If their computer has a firewall (and you don't have access to their computer), you cannot tell what programs they are running. That's one of the purposes of firewalls.

However, once they leave their computer, you can detect this.

One way is to put a sniffer on your network. That will tell you what traffic is passing by. Although there are plenty of free sniffers out there, very few will put your network card in promiscuous mode (the mode it needs to be in to see their traffic).

Second, try checking your router. Many keep logs of all the connections they make.

Third, install a proxy server. That way, all web traffic would have to hit the proxy in order to get out to the Internet. That way, you can see everything.

Finally, you could install a DNS server on your network and point everyone to it using whatever DHCP server you use. All requests for web traffic would then be routed through your DNS server which would cache the responses. I use one to speed up web browsing (my ISPs DNS servers are not that great), but you could use it to check traffic through the cache if you wanted to.

FYI: Most businesses use option 3.

I have 10 Windows XP Clients, 1 Windows 2000 Advanced Server configured as a domain controller, 1 Windows 2000 Advanced Server with SQL Server 7.0 installed and 1 Windows 2000 Workstation.

Here is the problem:

When the Win2000 workstation logs on in the morning and gets into the system, everyone else slows to almost a complete stop. If I unplug the Domain Controller after she logs on, everyone else speeds back up. If the domain controller is not plugged in the win2000 workstation can't log on. This is a serious problem and I can't figure out why the network would slow. My Domain Controller is the only machine with a 10 MBPS ethernet card. The SQL server sits outside the domain in a workgroup.

I have downloaded an SSH server called WinSSHD and an SSH client called Tunnelier. I'm attempting to have traffic encrypted on my home network.

The way i am attempting this is with a client to server setup, which means that traffic from laptop one is encrypted by the client which is also on laptop one, then sent to the server to be decrypted, and the server then sends that traffic to its final destination which is laptop two. The question i have is this... isn't this pointless if i have the ssh server on the same computer as the ssh client? Because then the traffic is sent to the client, encrypted, sent to the server, decrypted... all while being on my local machine! It's then tramsmitted unencrypted to the second laptop. Is that what happens? If i'm right about this, then are there any web based SSH servers which can be used instead of a local one installed on my machine? And i know a solution might be to install the server on laptop two, but this isn't how i'd like to achieve this.

Thanks for any repiles.

A:trying to encrypt network traffic using SSH

Only the portion of the traffic between Tunnelier and WinSSHD is encrypted. If Tunnelier and WinSSHD are on the same machine, then no external traffic is encrypted. In order to encrypt the network traffic, you need to install the SSH server on the machine you are accessing.

If you cannot do this, you need to install some crypto software on the destination machine, which crypto software needs to interoperate with the software installed on the source machine. I.e., if it's not SSH, then it needs to be something else, but whatever technology you choose, the crypto needs to be on both machines.

Using an internet server won't help you for encrypting local network traffic, unless, again, you install some software on both machines that accesses the internet server securely and passes the data through it. Such a solution will also be considerably slower than a straight LAN connection.

I'm looking for a good network analyzer software that allows me to monitor the network. maybe have some features on discovering devices, ports, bandwidth in a certain amount of time, etc. Thanks.

A:network traffic analyzer

That would depend on the network topology. Any global network monitoring will have to be done with access to a common point where all the traffic converges. Addressed traffic between workstations will go directly between them via any switches and gateways in the path, so you can't do this with just a workstation.

the computers are connected with the cisco switch.
Every Nodes on our network using PIX internal IP

please help me by proper susession.


A:Network traffic problem

you may also want to use network monitor to find the problem.

here is the case study we had. quoted from http://www.howtonetworking.com/casestudy/spywareblockinternet1.htm

Case Study - Trojan and spyware block accessing the Internet

Situation: Small Company has a Linksys router connecting to the Internet. In the early morning, accessing to the Internet seems to work fine. After half hour or one hour, accessing to the Internet is slow and slower. Eventually, no one in the office can access the Internet. The temporary solution is reset the router or reboot all computers.

Investigation: 1. We checked and tested all hardware connections such as NIC and cabling. They are OK and they donít have any issues to share files and printers.

2. TCP/IP configuration looks good too. Used nslookup to check the status of DNS and it looked good.

3. Network Monitor and the log of the router listed a lot of packets sent to the router.

Resolution: Based on the Network Monitor and log, we found the problem computer with many Trojan and spyware. After we cleaned the computer and install a firewall, they donít have the same issue any more. A happy ending!

Is there a way I can measure the bits/second going into/out of a given network port number - such as 9090? I need to separate the rate of network traffic going through port 9090 vs other ports (such as port 80, for example). 

Is there a program that will provide that information?

I have a laptop and a desktop networked through a router. The laptop is attached to a domain (running Win7 Enterprise 32-bit), the desktop is not (running Win7 Professional 32-bit).
In the "Network" folder on the desktop, I can see the desktop and the laptop, and I can access both. Same on the "Network Map".
But on the laptop, in the "Network" folder, I can only see the laptop. Any attempts to access the desktop by IP address or UNC path are met with a network error ("Windows cannot access \\desktop"). The desktop appears in the "Network Map" but it cannot be clicked or otherwise interacted with.
I have a homegroup set up on the desktop but I cannot join it from the laptop.

What do you think I can do to allow the laptop to see the desktop?

Hi Everyone and thank you for taking a look.

I work on a road project in a rural area here in SL and we have very limited internet connectivity in my office of just 120gb package per month.

but here other employees are using this to download torrents and they have already eaten up 70gb on this month's package. so my bosses are asking me to control the traffic.

so heres the situation, we have setup a network using dhcp and this router (Tplink TD-W8950ND) doent have QOS settings to block incoming ports but to block outgoing traffic from ports(I really hope of blocking p2p ports, thats why I mentioned about port blocking).
I have a computer with administrative rights connected to the router directly and some of those other computers are connected as well with administrative rights. so we cant disconnect them by force as it would cost some complications.

so in short, what I wanna do is to block all the incoming p2p traffic on the network so we may save some bandwidth and data for office use. how can I do this on this situation?
(note: ipcop or anything requires to use a whole separate computer to setup a firewall or something like that isn't an option here. )
Thank You very much and any help is greatly appreciated

A:Blocking p2p traffic on network


There is no fool-proof way to block all P2P traffic on a network with non-enterprise equipment, particularly brands like TPLINK.

The problem with P2P programs is they can change the ports they use. Additionally, if your router supports uPNP (and most do), ports can be forwarded via upnp. Some p2p programs can randomise their port too.

Some of the methods you can use to reduce the P2P traffic are:

1). Use OpenDNS and select the P2P/File sharing category.
2). Block known P2P ports.
3). Grab a higher end router
4). Set up packet filtering rules for specific machines (by IP or MAC address)
5). Use a proxy server.
6). Install a third party firewall (such as PIX or Kerio), for blocking some conent.

This list is by no means exhaustive.

for (4) above: At the risk of being too technical, with packet filtering you will get a good level of control. You could open only those ports needed for business use (such as 80, 443, 21, 25, 110), and use a "Implicit Deny" which means that everything else is blocked. But as I said, this is a fairly technical solution. If you're not familiar with packet filtering you'll need to find someone who is.

Here is a site that gives a little info on common port usage:
Common Application Ports - Bandwidth Controller

This may also be of use, but it is quite technical.
TCP/IP Ports

I'd be creating a formal policy on Internet usage at work, and have strong consequences of inappropriate use. Ultimately, that might have more success... Read more

Is there a program for windows XP pro out there that I could use to trace the source program that is causing excess network traffic (seems to be datagram traffic as it is in most cases only outgoing without replies)?

I have tried "task manager" and it gives me little indication of the offending program as the CPU usage is so low across all the programs using CPU.

Not sure if this is related but my Norton Antivirus now seems not to be able to get definition updates and the subscription is still valid until 2004??

I used a packet sniffer to identify the traffic and most of it seems to be going outside the local network to many different IP addresses.

Is there a way of setting up or checking a log to identify the program?

While I'm playing Battlefield 2, I get a warning of a connection problem. This lasts about 4 seconds, then again about 3 seconds after that. This used to happen once every half hour or so, but its become much more frequent, to the point where the game is unplayable.

I have a network meter gadget on the desktop and I've noticed a spike in traffic at about the same intervals. At first, I thought it was Skype or Avast to blame, but I can count them out after stopping each one.

I need some way to log which program accesses the network at what time, so I can compare the spikes to the correct time and hopefully find the program responsible. Is this possible?

A:Can network traffic be logged?

Here are a couple possibilities. I have used both with Windows XP Pro but tested neither with Windows 7.

Wireshark will log all packets, which will allow you to analyze what sites the traffic is to and examine the packets themselves to whatever depth you care to look. I've seen references to running this on Win 7, even 64-bit.

The SAX2 Intrusion Detection System is perhaps a simpler approach; it will show you the connections that are open and the number of packets sent to each connection. Vista is listed as a supported OS but I've seen no mention of Windows 7.

So first off I noticed my internet suddenly started slowing down a few days ago. I also found that on World of Warcraft I'd be in the red and the game would lag. Upon looking at my traffic I was having frequent spikes of 1MB download with larger spikes of 6MB with no obvious programs that would be using this much traffic. Right around the time this happened I got a message saying Powershell had stopped working. Then not long after I got a message saying something from Netstat being breached or something.
Shortly after my internet started to lag. During spikes I can't access websites etc. Very annoying.

I immediately started a full system scan with Avast and found

win32: Dropper-gen [Drp]
Java: Malware-gen [Trj]

All were deleted successfully. I also did a boot time scan and a malware scan with Malwarebytes and found no other infections yet the problems exists still.

I also swapped out modems. I received a wifi router/modem from Comcast but already had a router so I had it bridged to mine and wifi turned off. I logged on to the Comcast modem and found all kinds of devices etc that I didn't recognize and somehow the settings were all different then what I had originally set it at. It was password protected as well so I was a bit confused. Any changes I made to the Comcast router didn't seem to save either! Today I got rid of it (think this was the source of the breach) and got a regular surfboard modem.

<font face="Tahoma" size="2">
Hi all,

I'm experiencing some problems with a standard 56K dial-up connection in that (after the handshaking) no traffic is occurring between the PC and ISP host.

This PC did have a firewall (Norman Internet Control) installed, which ceased to work after a mailbox filter application was installed. Both these apps have now been uninstalled, but still nothing happens with the dial-up.

I'm fairly sure that I purged the registry of related information, however some Windows services remain; they are not started though. The O/S is Windows XP Home Edition.

Also, this DUN connection works fine on a different PC, with the same settings, so I've pretty much ruled out a bad server connection.

Has anyone seen anything like this before, or know of any tools to analyse the traffic with a view to identifying blockages or faults ?

Any reply appreciated.

A:Dial-up Network Traffic (or lack of)
