[TriLUG] Linux DNS Server issues with DOS client

[David Rasch]

Roy,

I'm almost positive that the client for DOS uses a NetBIOS/WINS lookup 
as its primary method of resolution rather than DNS. 

I'd try:
1. setup a samba server (nmbd is all you really need.  Give it the " dns 
proxy" configuration directive to pass unresolved WINS queries on to DNS.
2. Make sure your DHCP or static configuration in the client uses the 
WINS server by IP and has the resolution type set to 0x8

Good luck,
David
