Hooray I'm back !
A virus scan today found Troj/Badsrc -A
So this may be Malware related, usually if you have one infection there may be others as well. In a large network it is difficult to isolate the infection, especially if there is file and data sharing happening.
I've gone back over the original posts and found a lot of information on Server 2003; security updates; network packets; even a small update called
afsinst.exe
But the Trojan issue must be addressed first. Otherwise we might be chasing our tail a bit.
From what I gather, if you isolate one computer with a clean image, everything is fine. But once connected back to the network, after some time interval, eventually you start receiving these errors.
Have you run CCleaner and removed all temporary files on all computers?
Temporary files not only take up space, but can also slow networks down, due to the increase in single computer processing of cache and updating logs and eventually replying back with information themselves.
Therefore you first need to clean all computers out of junk files.
Have all computers completed all Windows Security Updates, and are all computers fully protected by virus (are they running their own AntiVirus)
You may need to run a full scan of Antivirus on all computers, ideally at the same time. (only after doing the previous paragraph first)
I needed to this myself once, trying to chase a virus on a large network. I eventually came in on a day when the computers were not required (usually a Sunday) and started all computers scanning in Safe mode (updated first)
I was able to remove one single virus, and all was then ok.
There are a number of free tools to use including
SuperAntiSpyware Ad-aware and others (x a lot !) I think this is your first approach.
In simpler terms:
1. Clean (not just the standard Windows clean!)
2. Update (including Antivirus and Window security)
3. Scan (from Safe mode; multiple tools)
Is this possible?
If not. I really am unsure of what steps to take.
How long have you been aware of this issue for anyway?
