Slow Logon

[Mitch Peterson]

We have four Windows 2000 PCs that take 15 minutes to get
to the desktop after logging on. The problem started on
these PCs within 1 or 2 days of each other. The problem
has not spread to any other PCs in our organization (over
100 PCs)since.

We use NAVCE and keep it up-to-date. I've run a scan just
to be sure, and no viruses. We also keep the PCs patched
thru Windows Update. We have not installed anything else
on these PCs in quite awhile. Things I've noticed:

- The "Loading Profile" screen shows up, the WAV file
plays, then the screen goes to the Windows background
color...no task bar, no icons. Mouse still works. CTL-ALT-
DEL does not.
- The "A" drive light goes on for a couple of seconds.
I've looked thru the registry for any references to the A:
drive and all I found was a WinZip key; but WinZip does
not automatically load with Windows.
- After 15 minutes, the desktop appears, the programs in
the "RUN" registry key load, and the startup folder
programs launch. Computer runs normally after that.
- The problem is with the PC, not the user. Doesn't matter
who logs on to the PC, the same problem occurs.
- If we log on to the local PC instead of the domain, we
do NOT experience a delay.

Anyone have suggestions? Can anyone point me to a
technical document that might explain what Windows is
doing from the time it plays the WAV file and the time
that the Desktop appears?

Do these PCs point to the same DNS server as others that don't have this
problem?

The antivirus software is probably taking the time to scan the user profile
as it is being loaded. On top of that, the profile may be abnormally large.

DNS servers are fine, but thanks for the suggestion.

Thanks for your suggestion. The user profiles are not
abnormally large. We have a group policy to control that.
The other point is that the problem does not follow the
user, it stays with the PC.

I actually removed NAVCE because I have had corrupt
signature files in the past, but this made no difference.

I had a similar problem I found that the following process:
c:\winnt\system32\ahctres.dll that is mentioned in the registery in
winlogon/notify entry, and causing the problem, could not figure ou
what it is. Had to reboot from cd and remove the files, than remove th
entry from the guardian registery. It looks like a trojan or virus.
