Thanks Knottyrope
I didn't have the windows account with Server administrator rights in the SQL DB
However I am still getting the "Unable to open BESMgmt database: Login failed for user '(null)' . Reason: Not associated with a trusted SQL server connection.0x80004005 NativeError=18452 Error Initialising BES. Terminating"
I wish I had a SQL Admin but ours ran away to Oz
Is it possible to recreate the SQL DB and whack all the back in? Or take the current one off line and then create a new one and then delete it and then readd the old one? Or is that just me grasping at straws?
