Connecting a Active Directory Domain Controller on a specific port
Heyas,
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.

Disable the window firewall and antivrus if any and reboot the cleint machine and check.If any thirdy part security application is installed then disable the same too.
can you please if PC is able to telnet itself on any well known port ?
For example, TCP 135, 445
If not,
Please disable firewall and antivirus software if any to check if installed antivirus is blocking him from communicating with DC ?
Also check how many network cards does this PC has ?
If you found multiple, then please disable all unnecessary cards and check ?

Nothing again, update I can't access the PC itself via telnet from the DC. Does this provide any further insight?
Please try to telnet PC from same PC only instead of DC and check if its able to telnet itself
Please download PortQueryUI tool from microsoft and check if you are able to telnet domain controller
