System cannot log you due to the following error

I have a Windows XP machine part of a domain, after installing SP3 on Moday night the system worked fine up until Wednesday morning at which time when trying to log on I get the message The system cannot log you on due to the following error: The specified domain does not exist or could not be contacted.
When selecting the option "Log on to:" the system tryies to create a list but only returns with the local machine (this computer) and when using the Admistrator account/password I get the same reponse.
When trying safe mode the same result happens.
Therfore I can not logon to the local or domain!

I can ping the machine and can connect (but not logon) using a remote connection therefore the network connection is valid and working.  Othe machines on the network are fine.
Any ideas?

Since you can't logon locally, as you stated, you can try and reset your local administrator password:

Then eremove the PC from the Domain through Computer Properties AND directly on the server in AD Users and Computers, the  rejoin the domain.

Did you try to remove the machine from the domain,delete the machine account on the AD and again join the machine in the domain .

1.Login with the local admin account and post the event log errors here.

2.Also run windows updates and install all post sp3 patches and go for a reboot.

3.Did you check for the DNS settings on this machine....confirm it points to the correct DNS servers.

Unfortunatly this machine is over 250km away from me so I will have to go visit it.
Kutyi has the best suggestion so far and I will have to try it next week.
Point of interest as I mentioned I can ping it with the IP address but not with the name, the PC is no longer listed in the AD (I did not remove it) however I can map to the machine\c$ so I have been able to recover the data.
