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.
