Receiving "Error: 18456" when for a specific user who has rights via AD Group

I have a user who is a domain admin and has rights based on a group
policy (OURDOMAIN\Developers) to access the SQL Server. He can access
other Sql Servers, and every other member of the group can access all
boxes. So its a case of a specific users cannot access a specific
box. Below is the error message he is getting:
TITLE: Connect to Server
--
Cannot connect to SQLDEV1.
--
ADDITIONAL INFORMATION:
Login failed for user 'OURDOMAIN\user'. (Microsoft SQL Server, Error:
18456)
For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server&EvtSrc=MSSQLServer&EvtID=18456&LinkId=20476
--
BUTTONS:
OK
--
SQL2005 Ent SP1 on Win03
Any ideas would be appreciated.Hi

Maybe you are seeing http://support.microsoft.com/kb/925744/en-us I believe
3152 is the latest version you can download if you want to move past SP2.
John|||You can more details about login failures from the SQL
Server error log on SQL Server 2005. Check the log for the
State - there will be a line similar to:
Logon Error: 18456, Severity: 14, State:18
Then check the corresponding description for that state in
the following article:
