Hey Eric, Is the W2K box already a member of another domain? Is there anything filtering traffic between the DC and the old server? I think occasionally we also had to use the complete dns name when trying to add. (ie domain.com not just domain).
Weird though, never seen that before. -Troy -----Original Message----- From: Eric Brouwer [mailto:[EMAIL PROTECTED] Sent: Thursday, December 11, 2008 5:55 AM To: NT System Admin Issues Subject: Issue joining 2003 domain Good morning, I am trying to join one of our legacy W2K boxes to our W2K3 domain. I am logged in as the local administrator, and when I try to join I am passing my domain admin credentials like new_domain\administrator. I am getting the following error: Network Identification The following error occurred attempting to join the domain "new_domain": No mapping between account names and security IDs was done. I can ping the new_domain DC by name and IP, and I can see the new_domain from Network Places. Any one ever run into this?
