Domain is 2003 interim, on a 2003 R2 DC
server is on 192.168.0.0/24 subnet
machine is on 172.18.5.0/24 subnet
I am unable to telnet from machine to DC on port 389 but can on other ports e.g. 53 for DNS
I can ping the server and use if for name resolution but when I try to join the domain I get the error "computer name changes: the following error occurred attempting to join the domain the specified server cannot perform the requested operation"
I have tried adding a DNS suffix for the domain, joining using NetBIOS name, adding a new AD site for the subnet I am joining from.
Just found the following in the DNS event log on the DC "The DNS server received a bad TCP-based DNS message from 172.18.5.1. The packet was rejected or ignored. The event data contains the DNS packet."
