On the Journey to be a SQL Server Professional: SQL Server Error - How to rebuild the system databases

SQL Server Error - How to rebuild the system databases

Need to stop both SQL Server Services and SQL Server Agent Services
Find sqlservr.exe. It is in different folders in 2005 and 2008.

In 2005: C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Binn
in 2008: C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLServre\MSSQL\Binn

If there are errors, especially in 2008 such as InitErrLog, run the command prompt as an administrator.
Run the command in single user mode: sqlservr -m, then use the setup.exe option to rebuild one of the system databases (see 2005 DBD book p.541 for details)
