The win 7 user cant logon Server 2003 domain suddenly. Event ID 3210, 5719, 1055 are logged on his computer On Server 2003 DC, it appeared the following error. Event Type: Error Event Source: NETLOGON Event Category: None Event ID: 5722 Date: 6/6/2012 Time: 12:35:53 PM User: N/A Computer: GMFS Description: The session setup from the computer EEDITION-LAPTOP failed to authenticate. The name(s) of the account(s) referenced in the security database is EEDITION -LAPTOP$. The following error occurred: Access is denied. Ive tried this command on Server DC.  "netdom reset EEDITION -laptop /domain:ABACUS" but failed and stated that Logon Failure: The target account name is incorrect Any solution? I think if need to re-join EEDITION-LAPTOP to the domain. But will the current user profile lost if I do the following steps. 1. Withdraw domain and change to workgroup 2. Restart and join the same domain. Then restart again. Many thanks.

no the user profile will be fine...That is what I would do to fix that error, make sure you delete the computer from AD after you leave the domain. Make sure it is the computer object and not the user object in AD. Then rejoin the domain
