Greetings.
I'm new in VS2005 , having P4 , 512 MB on XP SP2. Since last couple of days I'm facing problem as;

Up on selecting Web Site -> Web Site configuration , I'm getting " Unable to find a version of the runtime to run this application " message. After clicking OK , I'm getting another message as "Unable to connect to Visual Studio's Local Host server".

Pl. note earlier I have not loaded ANY version of .Net

I can see the result using IIS ( applications which are not based on Databases) not thru CASSINI becoz of this. I'm now not in a position to access Security configuration ( Asp.NetWebAdminFiles) thru application .

For database applications , even in IIS becoz of this I'm getting , "CREATE DATABASE permission denied in database 'master'.
An attempt to attach an auto-named database for file F:\DataBase\United.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share."

Pl. help / Guide me at the earliest.

Thanks
