Free Time Lookup Through Hub Server to a diferent Domain..?

I am trying to lookup calendar information --for a user in a server in the same intranet but a different domain

–from a Spoke server whithin my domain

Free time info shows unavailable.

When i try from the hub server it works fine… meaning the adjacent domain doc and connection is ok

Is there a method to tell the spoke server to go though the hub server for calendar info from the adjacent domain. ?

Thanx in Advance

The spoke server should use the adjacent domain doc to determine which server handles C&S requests.

Does the spoke server know that the user is in another domain from a directory to which it has access ?

Also, is Calconn running on the spoke server ?
