What is the hostname of the computer  your connection to? 

If it contains a dash or other special sign, make a cname of that computer without any special signs and try to connect to that cname with rdp client. 

And ! try connection to : hostname.domain.tld 

Last, any change the computer your connections has ethernet and wifi? 
( so if has 2 ipnumbers and one hostname ) 
If so, disable the wifi.

> It most certainly is not a DNS issue but just to be ultra sure the

> The clocks were also checked against those on the DCs, with a maximum

> Anyone have any theories about this? Or a solution?
