User cannot logon on any PC on the domain after migration

Hi can someone assist me with this issue. I am migrating users and computer accounts from a win server2003 AD to another win2003 domain using ADMT. On one instance one PC failed so i had to re-migrate the user account back to the old domain and thats when i get the error “cannot logon make sure username and domain is correct bla bla…” I try to reset password and logon to differnt PCs but getting the same error.
