Thanks. I have tried the following but it still won't login with sa in SSMS

- disabled all SQL services, except the main one

- -f -T3608

- start the SQL service with domain admin and local system

- disabled the network adapter just in case there is some unknown thing connecting to it

- disabled all other services on the server

Nothing fixed issue #3. From the log it looks like all the databases started up with CHECKDB returns no error.
