Can't Login from remote machines when local user is logged in

[Guest]

I have a Win2000 machine in a "workgroup" network that has about 5 user
profiles (all set to be administrators). I am trying to share a printer and
one folder on this machine. I have enabled sharing etc. and it all "seems" to
be in order. The problem is, a remote machine can only login to the system if
there is no local user logged into it (the login dialog is on the screen). If
nobody is logged into it, the remote machines can see the shared items
perfectly. The second the machine is logged into locally, it becomes
inaccessible to the network.

I realize I haven't much detail, but I have never seen this type of
behaviour before. Any ideas would be greatly appreciated.

I should also add, the error message I get when trying to connect is:
"the server is not configured for transactions".

It did turn out to be a virus and I beleive it is now fixed. I updated the
Symantec on the machine and ran a full scan. When the machine was rebooted
the scanner caught the culprit file as soon as it tried to start and wiped it
out. It now seems to work fine.

Thanks for your response!
