One of the PC on the network can't connect to the Windows DC it can ping with no issues, but when I try telnet through to it on the port 389 the PC is rejected. This is the only PC on the network that is doing this I have tried rejoining it to the domain with no success.
Any other ideas, bare in the mind I am a novice with AD.
You need to check if PC is responding to telnet protocol
Please logon to affected PC and open up command prompt and try "telnet ownIP 135"
If its unable to telnet itself, then there might be your problem
