[Samba] can connect to 2 samba servers by name but to one by IPonly

[Gaiseric Vandal]

nslookup on windows machines does require the FQDN name-  i.e. 
"pdc1.mydomain.com."

ping does not (windows will appropriately add the domain name.)

I have not tried "net use \\pdc1.mydomain.com" from a VPN connection.

I know that "nslookup" and "ping" in Windows have separate name 
resolution routines, and handle domain suffixes a little 
differently.     Again, that should have affected all machines.  
Machines on VPN connection get the "mydomain.com" appended to the VPN 
virtual NIC, but it is not the default domain for the machine.


I looked at my DNS server-  I can't see any differences in the entry for 
"pdc1" vs any other machine-  even though DNS is the only thing that 
would make sense.  But VPN clients use the 2ndary DNS servers for name 
lookup, not the primary.     I may try configuring VPN clients to use 
the primary DNS server.    None of the server names are 16 characters or 
more.


Thanks
