Connect to another computer not working

Hello,

Since dealing with Vista, it is not longer possible to connect to a remote
machines eventvwr or computer management via option "Connect to another
computer".
With WinXP-Client connection is possible without major problems.

I always getting the message: "There are no more endpoints available form
the endpoint mapper (1753)."

I do have the right of DomainAdmin, and the Local Output Firewalls is not
configured, so I guess, it's turned off.

Vista Version is Ultimate.

Any help will be appreciated.

Regards

Dominik
