Trouble accessing mapped drive from background process

I have a system service process that is trying to read and
write to a mapped drive but it unable to access the drive.

The service is set to logon using the adminstrative
account and both machines use the same administrator login
and password.

This works fine under W2K but does not work under the
either 2003 or XP now.

Also whats with the "./" infront of the login user name?

thanks
David
