Access Denied to most commands in console

Hi,

today I came across an issue i've never seen before, I applied a configuration to a machine... logged out of the server. today when i logon to the server and open the console I have no access to many of the basic tasks? eg If I refresh Clients, i get 

Access Denied: User does not have right to refresh clients.

manu of the other tasks are not greyed out? I'm running RU7. 

Any ideas as to that might be going on... I have checked and I have access to the sql server... the dsn seems correct.. i've rebooted the server and restarted most services but no joy
