WSUS error

Connection to database failed. Reason=Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.. Connection string: Data Source=MYSERVER\WSUS;Initial Catalog=SUSDB;Connection Timeout=60;Application Name=WSUS SQL Connection;Trusted_Connection=Yes;Pooling='true'; Max Pool Size = 100

Hmmm...

Things to check:

1. SQLAgent$WSUS running under LocalAdmin account - check

2. Check membership of the WSUS Administrators security group; I had no members in there...how did that happen? I added domain admins and domain controllers. (According to this: http://forums.techarena.in/archive/index.php/t-233723.html, a front-end domain controller needs to have a computer account in the WSUS administrators group.)
