Mapped drives disappearing

[Guest]

I have roughly 5-10 XP Pro SP2 in my domain that experience there mapped
drives disappearing. I have roughly 200 XP Workstations in my domain.

Upon investigation I found that selected services are stopping when the user
logs off. These services include the Browser service, workstation service,
and DHCP Service. Upon further investigation when I logged onto the
workstation as Admin I get a generic Host process error which through MS
error reporting indicated apply patch MS05-012. Each of these machines had
this patch previously applied. I reapplied the patch and the issue went
away. About 3 weeks later two users reported the problem again and
investigation found the same issue.

I ininitially thought it was the Symantec Anti-Virus V10.0.2 client but I
have put into place measures to prevent mapped drives from disapearing per
their KB article. Mainly disabling network drive scanning and startup
scanning. I even downgraded the client to a V9 anti-virus client and issue
still occurred.

The machines where in-place upgrades from W2K Pro approximately 6 months ago.

I opened a case with MS but they where extremely unhelpful. They wanted me
reinstall the operating system from scratch. I am in the process of doing
that but want to pass by this group to see if any ideas.

Thanks

Are you sure that the users at the workstation aren't pushing the delete
button on the drives, or unmapping them. Remove their permissions to do so on
there local machines. I would also check the firewall settings on the local
machines to make sure they have access to all network resources when logging
in. Also, check to make sure "automatically search for network drives and
printers" is unchecked in "folder options" that was a quick workaround for
me, when I faced this issue.

No on delete
Local Firewall is disabled due to having corporate firewalls
Will check into on folder option

Remember as posted core of this issue is network services are stopping.
Specifically the workstation service stops. If this service stops then
automatically the network shares become unavailable. As noted other
services, but not all, are stopping.

Are users permitted to logging into two different workstations concurrently?

Also try looking into the settings when users log off.

It might even be easier to tell users when they are done with a particular
computer for a while, or for the day, to restart the computer instead of just
logging off. This is good practice as all settings will be defaulted.

I am guessing this is a secuirty issue that prevents network access to
mapped drives when users log off, when they log off, services may be stopped,
and when they try to relogin, those services are listed in the startup for
the login. <- might not make sense, but tried my best

Bobby, thanks for trying!

Unfortunately, I don't think this is the case. Something is causing
selected services on these machines to stop. It is not an AD issue since I
would be experiencing it across my domain.
