DB2 6.1
OS NT 4.0

I've one instance with three databases.

Test1, Test2 & Training.

I'm able to connect to Test1 & Test2.

I'm not able to connect to Training and getting the following error.

I was doing some db2 cfg kind of command and suddenly command window stop working so i had to restart the server to make this command window work.

Before restarting this command window even i killed command window process and tried to run again but it was hanging there only.

So, i was in position to restart the whole server.

After restarting server when i tried to connect to Training - i'm getting this error.

Any one have any idea how to come out from this problem please ?
