We are having a problem on our network where users are losing their
connections to mapped drives after a certain period of time. This
started happening after they were switched over to Active Directory.
There are not many things in common, however, here are a few. They all
have:
Outlook 2003
SMS Advanced Client
McAfee Virus Scan 8.0.0 with the Anti-Spyware Module
Windows 2000 (some SP3, some SP4)

The drives are mapped from a login script, they are not locally mapped.
Here are a few errors from the error log which seem strange:

6:47:36 AM Information - Event # 5000

VirusScan Enterprise McShield service started - scanning for 128861
viruses.
Engine version : 4.4.00
.DAT version : 4502

EXTRA.DAT name : None
Number of virus signatures in EXTRA.DAT : None
Names of viruses that EXTRA.DAT can detect : None

6:52:58 AM Warning - Event # 4100

The COM+ Event System failed to create an instance of the subscriber
{6295DF2D-35EE-11D1-8707-00C04FD93327}. CoCreateInstanceEx returned
HRESULT 8000401A.

6:58:04 AM Information - Event # 4

Network interface has been reconnected.

Any help on this would be greatly appreciated. We are stumped on this
one and so far searches on Google & EventID.net have not helped.

I'm sorry, I should have put this in the original post, it slipped my
mind. The auto disconnect is set to 15, however changing it does not
help. We changed to 0 on a working pc and their drives were never
disconnected. We also set it to -1(never disconnect) on the affected
machines and the drives still disconnected. Same as if we switched it
to some huge number. They still disconnected after ~ 1hour.

This usually doesn't cause any problems. Either case the default timeout is
15 minutes. From a command prompt on the *server side*
net config server /autodisconnect:-1
for no disconnect.

Setting this from the command line may turn off auto tuning for the server
service. So a better solution is to navigate to
HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters

and set the Reg_DWord hex value of
"autodisconnect"=ffffffff

If "autodisconnect" doesn't exist, Add it.

It has to be done *server side* of the connection.
