Can't log AD user in

Hi All

Any ideas on this one:

1) Dell laptop XP Pro SP2 has been added to the domain OK via the My
Computer/Computer Name/Change tab. If I go back and look the domain has
been accepted correctly.

2) Laptop has a unique computer name.

3) Laptop is set to DHCP in network connections (follows same LAN setup as
all the others in the domain) and has the Windows firewall turned off. No
3rd party firewall, protector, etc is installed.

4) I can log onto the laptop's local user accounts OK as the administrator
and a standard user account.

5) I'm connected on the 100MBs LAN, as I can actually go Run and type in
\\server and bring up all of the shares on my Win2003 server.

6) I can get out on the Internet.

BUT, I cannot connect to a user account on the server. I've tried various
working ones and every time it says the domain controller cannot be found -
even though all of the other machines are connecting and working OK.

Any ideas why it won't login?

Thanks

you can check DHCP settings;
if you use a dhcp on router or win2k3.you can make sure a corretly assign
DNS.
you can query web adress using nslookup and then review settings.

You have probably (manually or in DHCP) set the IP DNS Server to use the
ISP (or other external) DNS server. Otherwise you likely have trouble with
your DCs registration in your internal DYNAMIC DNS zone.

Internal machines (including DCs) must use STRICTLY the internal DNS server
(set) which can resolve your DCs.

Also, every DC must pass "IPconfig /all" with no FAIL or WARN messages.

If in doubt:

Post the unedited text output of "IPconfig /all >compname.txt" for both
client
and DC as well as the unedited text output of a complete "DCDiag /c".
