For the primary server itself, w2k03,

Setup rules according to;

office 1 =
office 2 =
office 3 =

and, match = 1

and the server at shows up as
"configuration location uknown"

Also, in the list of the configured locations, there was (before I
create our own) a defintion called "unknown" allready.
This unknow definition can NOT be deleted/edited or anything.

If I do a zac cl at the prompt, the guid shown matches (off course)
the above unknow definition....
