Thnx for the reply @ pootle .. yes all that i mentioned is on one machine it self... and the Server Name while logging in i use is : SAURABH-49F41DD. I have also tried to log in using (.) or loacal server as the servername .. no use... Dont know if this would be of any help but my comuter name also happens to be :saurabh-49f41dd. i.e same as the server name i use to log in..
I also would like to know what is a SQL instance.. and how would u check if it is installed...I m sorry i may sound very dumb but kinda new to this.. Any Help would be appreciated!
