Logon Problem on One Client

Using 1 SBS 2003 (DHCP Svr & DNS Server), 1 Server Std 2003, 5 XP Clients
SP2, 1 2000 Pro Client

Problem is with one XP client that won't logon if DNS address is set to the
SBS address like the other clients. It can logon if DNS addresses are set to
the ISP DNS addr, which are same as fowarders on the SBS, but then it won't
load the Group Policy. If machine is left idle for a while, opening files on
the SBS becomes slow, have to log off/on, sometimes multi times to get it to
work.

Other clients are set to obtain IP/DNS auto, this one client obtains IP
auto, and will obtain the same DNS (the SBS address) auto as the others, but
won't work. DNS must be the ISP's (or at least not the SBS) to logon.

Also, the clock on this XP client is not sync with the SBS like the other
clients.

Any ideas? I can get more info if needed, machine is presently being used.

What exactly is the error that you get when trying to logon when pointing to
the SBS box for DNS?

First of all sync up the clock manually on the XP box so that it is within a
minute of the clock on the SBS box, ensuring that they are also configured
for the same time zone. If the clocks are out of sync by more then 5 minutes
it will not let you log on.

The only reason you are able to logon when you point to the ISP for DNS is
because you are unable to find a domain controller because there is no SRV
records for your DC on your ISPs DNS server, and since it cannot locate a DC
it is logging you on with cached credentials.

Another potential problem could be that the secure channel between the
machine and the DC has broken. If syncing up the clocks does not work try
disjoining and rejoining the XP box to the domain.

Thanks for the reply,

The error is "The system could not log you on. Make sure your User name and
domain are correct, then type your password again. Letters in passwords must
be typed using the correct case."

Of course the username and domain are correct.

I sync the clock and tried disjoining and rejoining the comp to the domain,
still have same problem.
