Re: TCP limit & network issue

Well it took more than a week to prove, but the problem seems to have
been Symantec's Norton anti-virus (NAV). Once it had been uninstalled
and AVG installed all of the networking issues went away. The disconnect
issue, the slow speed and also a slow copy and paste issue my wife told
me about after the NAV had been uninstalled. Apparently the networking
issue was causing slowness in general at times.

What really frosts me is that when I told Symantec tech support what I had
done they did not acknowledge the issue or provide a fix. They cut off the support
back and forth when I asked them for a fix or to tell me that they did not have one.
Apparently they do not feel that their product has an issue.

At this point anyone who wants to use Norton Antivirus on Vista computers
that are set up in a peer-to-peer configuration should think twice about it until
they have proven it does not cause them any problems.

Thanks for suggesting using another antivirus package. I do not know if I will use
AVG in the end, but it is a strong contender.

Thanks for all of the answers.

I had previously researched the event message and I also discovered that
Microsoft knows better. What is not clear is how many connections Vista
can have. Some say 2 for Home and 25 for Ultimate or 10 for Vista. 2 sounds
a bit on the low side and since the problem machine has Ultimate even 25 sounds
low. Microsoft's explanation for limiting the number of TCP connections to a static
number seems to make sense on the surface. But it also has the effect of making
you buy one of their server products to do any real file sharing in a client/server
type of relationship (which is what we are doing).

I am not running any file sharing stuff other than what comes with Vista.
Nor do I believe that these two machines are compromised as someone else
suggested. My firewall would be picking up the traffic and there would be other
signs. I have used Wiresharks ancestor Ethereal.

It had been a minor problem happening once or so every week. But when I
Installed Norton Antivirus 2009 it got MUCH worse and happens a few times
per day now. So it appears to me to be related. Unfortunately Symantec suggests
running the computer with Antivirus shut down to see if it is their product or not.


Try downloading AVG free + latest definitions (or one of the other recommended free antivirus). Download your latest norton definitions plus malware definitions ( you do use anti spy/malware program??) + any norton removal tools required for 2009 (from my own and others experience just uninstalling doesnt remove all of it). Then go off line, scan all to be certain, then uninstall NAV fully and install AVG with latest definitions so you are safe to go back online while you are testing.
