[Samba] Problem since upgrade to 4.5.1

Since upgrading our DCs to Sernet Samba v4.5.1 we are experiencing 
problems using Remote Desktop from Windows boxes. The rather useless and 
completely misleading error message states:

"The connection cannot be completed because the remote computer that was 
reached is not the one you specified. This could be caused by an 
outdated entry in the DNS cache. Try using the IP address of the 
computer instead."

We are able to RDP using the IP address from a Windows machine. We are 
also able to RDP by either name or address from a Linux machine. It's 
only when we try to connect by name from a Windows machine that we have 
this problem. It all worked perfectly fine prior to the Samba upgrade.

It most certainly is not a DNS issue but just to be ultra sure the 
caches on both the client and destination boxes were flushed, We also 
rebooted both machines.

The clocks were also checked against those on the DCs, with a maximum 
discrepancy of one second. The time on the two DCs matched to within 
0.002 seconds.

Anyone have any theories about this? Or a solution?
