samba - Jul 2004 - Drive mapping failing

Hi,

I have a 2.2.8 Samba server setup here that is mapping Unix
home directories to a drive at login for Windows XP and
Win2K Pro desktops. I'm using server level security, the
password server being an Active Directory server.

This works consistantly well.

I've introduced a Win2K Server with terminal services and
Samba will fail to authenticate after only a very few logins
complaining that the password or username is invalid.

I also periodically get "System error 1326 has occurred"

Has anyone else used Samba in this way and seen an issue
with Win2K Server?

smb.conf included.
