Actually its trying to do a reverse lookup on 192.168.1.254, but it failed.

Actually, the "broadcast" is the netbios node type. i.e. How does this W2K
system announce its MS workgroup/domain affiliation on the network...
broadcast or WINS (Network Neighborhood stuff). This has nothing to do with
DNS.
Although this is OT, from the dhcp-options man pages...
option netbios-node-type uint8;
The NetBIOS node type option allows NetBIOS over TCP/IP clients
which are configurable to be configured as described in RFC
1001/1002. The value is specified as a single octet which identi-
fies the client type.
Possible node types are:
1 B-node: Broadcast - no WINS
2 P-node: Peer - WINS only.
4 M-node: Mixed - broadcast, then WINS
8 H-node: Hybrid - WINS, then broadcast

Although I don't disagree with the above, the DNS suffix is typically
used/set in the connection specific part of ipconfig. i.e. Each interface on
W2K can have a DNS suffix.

Also, this is my personal preference, not a recommended policy. But I
disable W2K's caching server. This fricken thing has caused me more greif
than I care to mention. Try and tell a regular how user to flush the cache.
That will go over real well...
