User Accounts

SOLVED

I had to rename a user account in Active Directory due to marital status. For example.. TJJONES to TSMITH. When I try to add the user account I receive an error message. I am adding the account vis the System Manager, Maintetnance, Maintain Users. The changed user account (TSMITH) appears in the list of domain users.

WIndows NT user or group "domain_name\TSMITH" not found. Check the name again.

Cannot find the login "domain_name\TSMITH", because it does not exist or you do not have permission.

Any ideas?
