I noticed lately that I am not able to RDP to the server locally. I just took over as an IT guy/paramedic for a local fire station and they have DYDNS for external connections. Inside they had to use 123ABC:3389 if they wanted to RDP both inside and outside. Then one day RDP just stopped working. I have since reformatted a bunch of machines, moved DHCP from their WNDR4500 to the server 2003 machine. Hoping I can just RDP to it but I cant however any new machines I have reformatted since can RDP with no issues. I have done the basics such as ensure RDP is enabled, the user is either an administrator or a remote desktop user etc however still no go. Any thoughts?
