Yes, it could be depicted in a simpler implementation where you're trying to browse to a site that takes too long to respond, the calling end times out, returning something along the lines of "Remote server not responding" errors from a browser. > > Other interesting tidbits of info to confuse the matter: > > DHCP NBT nodetype is set to h-node (hybrid) > WINS database doesn't show all computers. WINS is supposed to be able to dynamically update its db where for instance, a client has moved to another network point - > Corrupt database?

Depends on what modes the clients are configured to use: Modified B - Use only broadcasts - DNS (default for Win2K not using WINS) H Mode - Use WINS only first. Fallback to DNS if WINS fails. Revert to WINS if available again later MS Enhanced H - Add LMHOSTS, DNS & host files as fallbacks to WINS What do you have set in smb.conf here: # WINS Server - Tells the NMBD components of Samba to be a WINS Client # Note: Samba can be either a WINS Server, or a WINS Client, but NOT both; wins server = w.x.y.z How is the samba server defined at the WINS & DNS Win2K servers? You might want to actually turn off WINS at the clients and reconfigure to use only statically defined entries in /etc/hosts.
