Slow logons to a win2k domain usually indicate a DNS problem.
You should eliminate this as a possible cause first.

XP differs from previous versions of windows in that it uses
DNS as it's primary name resolution method for finding domain
controllers:

If DNS is misconfigured, XP will spend a lot of time waiting for it to
timeout before it tries using legacy NT4 sytle NetBIOS.
( Which may or may not work. )

1) Ensure that the XP clients are all configured to point to the local
DNS server which hosts the AD domain. That will probably be the
win2k server itself.
They should NOT be pointing an an ISP's DNS server.
An 'ipconfig /all' on the XP box should reveal ONLY the domain's
DNS server.

( you should use the DHCP server to push out the local DNS server
address. )

2) Ensure DNS server on win2k is configured to permit dynamic updates.

3) Ensure the win2k server points to itself as a DNS server.

4) For external ( internet ) name resolution, specify your ISP's DNS server
not on the clients, but in the 'forwarders' tab of the local win2k DNS
server.

On the DNS server, if you cannot access the 'Forwarders' and 'Root Hints'
tabs because they are greyed out, that is because there is a root zone (".")
present on the DNS server. You MUST delete this root zone to permit the
server to forward unresolved queries to yout ISP or the root servers.
Accept any nags etc, and let it delete any corresponding reverse lookuop
zones if it asks.
