I needed to move the temp db that was in e:\mssql\data to c:\
This was temporary, because I was replacing the e drive. The sql application is installed on c drive in the default location, but tempdb was in e drive. I ran the code below and restarted the sql services and now SQL studio won't work for me. I can't connect to the server. Is reinstalling SQL server 2008 the only way to fix this?

USE master;
GO
ALTER DATABASE tempdb
MODIFY FILE (NAME = tempdev, FILENAME = 'c:\tempdb.mdf');
GO
ALTER DATABASE tempdb
MODIFY FILE (NAME = templog, FILENAME = 'c:\templog.ldf')

There should be information in the SQL Server error log about it starting. Look for that. tempdb being broken doesn't prevent the instance from starting.

Yes it does. If SQL cannot open and clear TempDB, the startup process will fail.

You are right (as usual), Gail. I thought it would start in read-only mode, but sure enough I get a failure.

The problem is probably rights. Your system cannot open c:\xxx.mdf as a file. You need to do this: http://msdn.microsoft.com/en-us/library/ms345408%28SQL.90%29.aspx

I think you are right. SQL may not have rights to the C: root drive. How do I change the location of the tempdb in sql server if I can't get back into the instance? Is there a setting in registry or something?

It talks more about the masterdb. I cannot try the suggested cmd's because the instance does not start.
