I am still encountering this issue, and have moved this topic from
vista.general to vista.networking_sharing (which I did not see earlier). I
configured the XP SP2 system to use NTLM v2 only, and this change did not
fix the issue.

A drive mapping gets disconnected when a user logs onto their computer
acting as the server and I cannot figure out why. Here are the facts:

Client Windows XP Pro SP2, workgroup member, same subnet
mapping drive T: using credentials VistaSvr\Administrator using
explorer
sharename connecting to \\VistaSvr\sharename$
able to connect T: when Vista computer VistaSvr\Administrator is logged
on, or if no one is logged on
unable to connect when primary user of Vista computer is logged on
using their domain account: domain\username
domain\username is not an administrator
existing working T: becomes unavailable when domain user logs onto
Vista computer
able to ping VistaSrv by name and IP from XP box
XP explorer error message: "The mapped network drive could not be
created because the following error has occurred: The specified server
cannot perform the requested operation."
XP cmd line error 58 when using this cmd: "net use T:
\\VistaSvr\sharename$ /user:VistaSvr\Administrator *" and entering
password when prompted
Same error messages occur with alternate credentials such as
domain\administrator

Server Vista Enterprise SP1, joined to domain, same subnet
no Vista group policies setup on WS2003 domain
simple file sharing disabled
VistaSvr\Administrator account is enabled, member of
VistaSvr\Administrators
firewall configured locally to allow file and print, IMCP v4
network discovery on
file sharing on
share name is hidden ie \\VistaSvr\sharename$
share permissions include full rights to groups VistaSvr\Authenticated
Users, VistaSvr\Administrators, domain\Administrators
default NTFS permissions for folder that is being shared,
D:\Storage\Sharename gives all users access


Note Google found this similar article:

but upgrading the client to XP SP3 is not an option in my case. I do not
believe McAfee Virusscan Enterprise is causing the issue, but is installed
on both systems (8.0 client, 8.7i server).

Hi,

Thank you for the post.

I noticed you created another thread which was a duplicate of this one.

In order to avoid confusion and keep track of troubleshooting steps, I will
close this thread as a "Duplicate" and continue troubleshooting the issue
in the original thread in vista.general.

Thank you for your understanding.
