do you have valid domain account.. have you selected the domain correctly during Login
(i never heard of XP 2003)
Yes I have valid user account and select domain name in domain box. Just one thing I have to add here when add domain user to local administrator group it will take successful login otherwise when domain users are not member then it give this message "The local policy of this system does not permit you to logon interactively". I did a lot of efforts which were in my knowledge but all in vain.
