DB02 running very slowly after SQL 2005 Upgrade!

Hi All

I have reciently upgraded our DEV ECC6 system to SQL 2005 and everything seemed ok - no problems really! However when we run DB02, to retrieve DB information it is taking about 4 to 5 mins to appear. This is obviously not good!

Has anyone else had this problem, and if so is there something that needs to be done?

Thanks

Phil
