[Samba] Problem since upgrade to 4.5.1

[John Gardeniers]

Hi Louis,

While it wasn't spelled out, it was firmly implied in my previous 
message that this problem appeared only after the Samba upgrade. Nothing 
else has changed that might impact RDP. There has been no change to 
machine names, IP addresses (we use DHCP reservations) or DNS entries. 
If a dash in the computer's name or DNS entry is behind this issue then 
it's clearly a rather serious bug in Samba.

regards,
John
