user cannot logon to some Terminal servers

AFter a time sync difference issue between a 20003 and 2008 dc that happened during night , which was sorted in morning and then the replication was fine as well .

Since then though users can logon to some terminal servers while cannot on few.  Their passwords dont work  even in accessing shares on those servers.

I have changed passwords , and tried few things  as restart  etc.

the error is :

This event is generated when a logon request fails. It is generated on the computer where access was attempted.

The Subject fields indicate the account on the local system which requested the logon. This is most commonly a service such as the Server service, or a local process such as Winlogon.exe or Services.exe.

The Logon Type field indicates the kind of logon that was requested. The most common types are 2 (interactive) and 3 (network).

The Process Information fields indicate which account and process on the system requested the logon.

The Network Information fields indicate where a remote logon request originated. Workstation name is not always available and may be left blank in some cases.


Any suggestion much appreciated
