Changed Domain, Cannot logon, Help!

[Dave]

We have the following problem:

We have an office that consists of 2 computers (1 laptop
with win2K professional and 1 WIN XP workstation) in a
subnet that is connected to a university network.

We only have 1 FIXED IP address so we use a Gateway/router
(D-LINK DI-604) to connect to the university network.

The D-LINK router gives out IP addresses dynamically to
our 2 computers in the subnet.

Both computers TCP/IP settings were updated to get an IP
address dynamically (i.e from the D-LINK router). This
worked fine.
We can use the internet and network printers...

Unfortunately the TCP/IP settings on the laptop computer
were changed so that the Domain was no longer used and a
work group was defined instead. Now the user CANNOT log on
to that computer because it seems that its not a local
user but a user for the domain.

Do you know how we can recover from this situation?

At login (using the known username and pasword) we get a
message something like. User account is blocked. Contact
an Administrator.

Please can you advise?

Replied in another group - if you need to post to multiple groups, it's best
to do so all at once in a single message (separate the NG names with commas)
so that everyone can follow the thread. Thanks

These are not IP settings but rather System settings. (The IP could
be messed up TOO, but the workgroup/domain is part of the System
identity, usually set in System Control Panel.)

Do you know how we can recover from this situation?

Reset it in system control panel -- and perhaps recreat or just reset
the Computer account in AD Users and Computers or using one of
the command line tools (NetDom, DSMod (Win2003), etc.)

At login (using the known username and pasword) we get a
message something like. User account is blocked. Contact
an Administrator.

Which account? Normally you cannot even CHOOSE the "domain"
unless the machine belongs to that domain (or a domain which trusts
that domain...)

The User account on the "machine" and the domain are NEVER the
same account -- even if they happen to have the same name.
