There is something else you can try. Can you go to the directory that the SQL binaries are installed (normally something like c:\program files\microsoft sql server\MSSQL10_50.<instancename>\MSSQL), go to the log directory and there should be a series of files labelled ERRORLOG*. Can you post a copy of the ERRORLOG file (the one with no number at the end)? If it has the startup info we should be able to tell you how to connect.
