HI TO ALL,
WE HAVE SET UP A NEW ORGANIZTION WITH A ROOT DOMAINWITH  (AAA.COM)AT TOP,AND
MULTIPLE CHILD DOMAINS AS  BBB.AAA.COM ,CCC.AAA.COM AND DDD.AAA.COM.THEN SET
UP EXCHANGE SERVERS 2003 WITH SERVICE PACKS 2 FOR EACH DOMAIN ,AND THEN
CONFIGURE THE DDD.AAA.COM DOMAINS EXCHANGE SERVER AS FRONT END SERVER.

IN OUR TOPOLOGY ,FOR DOMAINS BBB.AAA.COM  AND CCC.AAA.COM  THE
ADMINISTRATIVE GROUPS ARE DIFFERENT AND ALSO ROUTING GROUPS ARE DIFFERENT.WE
SET UP ROUTING GROUP CONNECTORS BETWEEN THESE DOMAINS.THE MAIL FLOW BETWEEN
EACH OTHER IS NORMAL.
OUR FRONT END SERVER AND CCC.AAA.COM IS IN THE SAME ROUTING GROUP ,AND
BBB.AAA.COM IS IN ANOTHER ROUTING GROUP.

MY QUESTION IS ,WE CAN NOT SEND MAIL TO BBB.AAA.COM FROM FRONT END SERVER,WE
TRY TO SET  UP ANOTHER CONNECTOR BUT IT FAILED.
ANY HELP WILL BE APPRECIATED,
THANKS FOR ALL....
