hey redshadow,
first go to the sql server installation folder and COPY all the contents of its data folder into another drive or folder.
Then uninstall and re-install SQL Server.
And stop the service of SQL server from the service Manager, and then copy all the contents of the previous data folder onto the new data folder, under the new SQL Server instlallation folder. then re-start the service again. Lo and behhold! your originaal databases and table are there as it is.
But if there is a corruption you say, then what exactly is the problem ?
RENAMING the SERVER NAME MAY NOT EXACTLY BE THE SOLUTION. It depends on ur problem..
Mail me with your problem detailed at cdhruva@usa.net , and I will give you the best and fastest possible solution.
