Hi list, Although this doesn't really matter, I'm wondering if anyone can figure this out. From a W2K machine, I try to view the netbios table of an XP Pro machine by entering: nbtstat -a RAY "Host not found." is the response. * If I nbtstat it by IP address, that works fine. * It's not a "a" vs. "A" issue. * Both the W2K and XP machines allow netbios over tcp/ip. * Neither machine is running a firewall (including the built-in XP one). * I have a WINS server on my network, and both machine are set to use it. * I can nbtstat the other machines in my domain by name from the W2K machine without problem. * I can nbtstat the other machines in my domain by name from the XP machine without problem. * nbtstat'ing the FQDN gives the same result. * I can resolve the host, RAY, by its WINS name and FQDN DNS name on the W2K machine fine. Any ideas? Thanks, Ray at home
