I have 3 different domains with domain user accounts, and one 2003 R2 file server in a work group.
On the 2003 workgroup server I created local users with passwords that match the user/password on the domain. I added the local users to the local administrators account.
This allowed user domain\adam to mount share from the 2003 server without having to type in domain/user/password info. As long as the passwords were in sync they could attach from any domain.
Tried setting up a Windows 2008R2 server same way, left in workgroup, locally created users with matching passwords added to local Administrators group.
When I try to mount a share or the C$ share I'm prompted for domain\user and password.
I have confirmed that account usernames and passwords match.
Not sure why this is working on server 2003 and not 2008.
Overall goal is to allow accounts from mutiple domains attach to shares on this system without getting prompted for password.
