hi need your urgent help on this

I have got an instance of sql 7

the problem is if I want to register that instance in Enterprise Manager with the name of . for local instance (on the same machine) it will work fine. If I try to register the instance with the server name LOOP, it can not as it can not establish the connection.

I have tried with query analyzer as well
with . (as local ) I can connect to the instance but with LOOP no chance.

From another computer in the same domain , I can register the instance with the name LOOP with out any problem.

I'm confused
