I installed SQL Server 2008 Enterprise Edition on Windows 7 Ultimate from sadegh user.

This account exists in administrators role. after a few days I removed sadegh user from Windows and now I am using administrator user. But I can't login to SQL Server database engine using Windows authentication method and I receive this error message:

TITLE: Connect to Server

Cannot connect to SADEGH-PC.

ADDITIONAL INFORMATION:

Login failed for user 'Sadegh-PC\Administrator'. (Microsoft SQL Server, Error: 18456)

For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server&EvtSrc=MSSQLServer&EvtID=18456&LinkId=20476
