Am instalat pe o imagine virtuala de windows server 2008, sql server 2008 express edition.
Am instalat sql -ul, named instance. Apoi am schimbat numele calculatorului.
Dupa acest pas nu a mai pornit sql-ul. Am incercat sa restartez serviciul, degeaba.

Am cautat pe net si am aflat ceva legat de "master".

Mesajul din fisierul de log
"  Error 5(Access is denied.) occurred while opening file 'C:\Program Files\Microsoft SQL Server\MSSQL10.SQL2008\MSSQL\DATA\master.mdf' to obtain configuration information at startup. An invalid startup option might have caused the error. Verify your startup options, and correct or remove them if necessary. "

Ce pot face sa pornesc totusi sql-ul?
