Hello, this may due to DNS / connectivity ptoblems. For DNS, proceed like that: Make each DC/DNS server points to its private IP addresss as primary DNS server and to internal DNS servers as secondary ones Make each DC without DNS points to internal DNS servers as DNS servers Once done, run ipconfig /registerdns and restart netlogon. After that, make sure that the client computer is pointing to the correct internal DNS server as primary one and try joining the computer again. If the problem persists, then check your routes, blocked ports ... This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.
