I am trying to add a slave server, but I gett an error message "One cannot add oneself as a slave server". I think it's has to do with the certificate, which I get from the 'cert' folder under 'program files\...'. Anyone have any idea?

Thanks.

If you add slave server to master it needs to point wizard to slave's certificate.

No problem that is done. Now i have a slave server, that is being lost from the group's administration server location...I can't add it though, cause it's already in the hierarchie.
