virus causing machines to have slow logon?

[gbl]

We have windows 2000 servers and mainly windows 2000 and windows xp workstations. Suddenly two of the workstations are taking a very long time to boot up to the logon screen.
Both took over 30 minutes. We use symantec av corporate edition 8.0, and all but two workstations are using their latest definition; the other two are using one from June 4. The two machines with a slow logon are using the June 5 definitions.
Is it possible that the long logins on the two workstations have somehow been transmitted a virus that was not covered by the June 5 update from symantec??
Do any viruses out there cause this kind of start up problem?

Hi,

Are these 2 Machines also XP? If so have you loaded the latest service packs.

Also do these machines have USB Devices.

I recomend that you remove any USB devices (if you have any) perform a system defragment and then reboot with the USB devices plugged in.

I had this and it worked for me.



Kind Regards, Paul Benn

**** Never Giveup, keep trying, the answer is out there!!! ****

Paul, thanks for your suggestion. I have since found it that the problem was related to one of our switches. The slow computers were all connected to one switch, and when I reset that switch thses computers all responded normally. No viruses that I can see.
Case closed!
Thanks again Paul.
