Took out the -m option from the registry- sqlserver startup parameters.....

Can able to login smoothly....

andras,

 Yes I believe there is something connecting by default before I try to connect.....

I am not sure about the console....all I know is it is a 2 node cluster active-passive....

did try thru OSQL......but still cannot connect....saya can only connect one administartor when in single user mode...

how to make sure that cluster administrator is not taking up the connection.....I did stop...

This is 2000 so there is no management studio....

I restarted the sql server many times even the nodes too but still it doesnt allow me to login becoz the startup parameters...
