Dropped from domain

Last night while I was surfing the net, my PC performed a cold boot.
I am hooked up to a UPS so I know it wasn't a power loss, though it
may have been a surge on the network.

After the reboot, the startup of XP was real slow. The "Applying your
personal settings" box stays up for a long time. After completing the
startup, I have no access to domain resources. I can access the
internet gateway and I can ping domain resources. It appears that I
am not authenticated.

I have tried to rejoin the domain, but I get an error stating the
network name cannot be found.

This machine has been working fine for months.

My domain is a Windows 2000 SBS server.

The workstation is running:

Windows XP Professional Service Pack 1 (build 2600)
2.80 gigahertz Intel Pentium 4
512 GB memory

I have the following patches applied:

I am getting a bunch of events in my application log that look like
this:
Event Type: Error
Event Source: Userenv
Event Category: None
Event ID: 1053
Date: 4/12/2004
Time: 8:50:36 AM
User: NT AUTHORITY\SYSTEM
Computer: xxxx
Description:
Windows cannot determine the user or computer name. (Access is denied.
). Group Policy processing aborted.
 
More info:

Initially, I could not attach to the Exchange server running on my SBS
server, which is also my Active Directory domain controller. Now I
can, my mail is now coming through and the Outlook client shows itself
as connected.
 
So is it solved now? Check the ipconfig/all and make sure everything is
pointing to the server-IP.
 
No it is not resolved.

Not sure what you were asking regarding IPCONFIG so here are the
results of an IPCONFIG /ALL 192.168.0.250 is the AD server and DNS
server.

Dns should *only* point to your server-IP, so delete the other 3.
ISP-DNS-numbers should be set in tab Forwarders of DNS-server.
 
This has been working for years and it works for my other
workstations. The primary reason I do this is because DNS confuses me
and I want to make sure my family can resolve their requests. Though
it isn't proper, it has worked and did work until the other day.

I am fearing the only solution at this point is to reinstall XP. I
dropped the computer form the directory, made it a member of a
workgroup, then tried to add it back to the directory and it failed.

Even worse, I no longer have my domain account cached on the machine
so I can on log on to the local accounts.

This is going downhill fast. :-(
 
Which exact errormessage do you get when you try to rejoin? And really, DNS
should *ONLY* point to your server-IP. You might try repairing the TCP/IP on
that XP.
 
When I try to join the domain, I get an error stating the
"network name cannot be found". I fear I will have to reload the OS
and start over. That is a bummer because I will have to track down
all my software again. I have licenses, but I moved in the past few
months and a bunch stuff got packed and is now hard to locate.

I do not really believe the DNS issue is involved. All my other
workstations are authenticating fine. That's 7 other computers. This
machine was authenticating as well. Something occurred to cause this,
and I am not sure what it was. Ever since the system reset, I've had
these issues.

I wouldn't mind addressing the DNS thing, but it is not part of the
problem and until I address the problem at hand, it doesn't help to
divert attention to other issues. Having said that, I do appreciate
your help and offers of information.
 
Hi Thom,

DNS is very important to an XP, so I still believe that it is your main
issue. Definitely if you get the error you get. Make sure that the TCP/IP on
that XP is set to obtain an IP and DNS automatically from your server. The
ipconfig/all should show that everything is pointing to your server-IP.
You've got options 003, 006, 015 in DHCP-server, Scope options setup?
You could try to reset the TCP/IP on that XP.
 
Hmmm, I do not quite understand. I am obtaining IP and DNS from that
server, but even when I statically assign the IP and DNS it doesn't
work. What are options 003, 006, 015 in DCHP?
 
If you want to obtain an IP and DNS from your DHCP-server, you should set
those options in DHCP-server, Scope options. That way they will get pushed
to your clients.
003 is router (if only using 1 nic, than it will point to your gateway, if
using 2 nics, it has to point to your server-IP)
006 is DNS which should point to your server-IP (you have setup DNS-server,
right?)
015 is your addomainname, e.g. yourcompany.local
Can you post the ipconfig/all from the server please and one from a client?
