HiWe are having trouble deploying Hub Transport role for a customer. This installation worked in our test lab but is not working in the production environment.Am attempting to install Hub Transport role on a server. Event logs are all clean. The attached logs are the result using the GUI. Have also tried command-line based installation, pointing to different DC's but the result is the same. Pre-install checks all pass OK. Event logs are clean prior to installation. However when I launch the installer for exchange, event 2152 is logged"Process ExSetupUI.exe (PID=452). An remote procedure call (RPC) request to the Microsoft Exchange Active Directory Topology service failed with error 1753 (Error 6d9 from HrGetServersForRole). Make sure that the Remote Procedure Call (RPC) service is running. In addition, make sure that the network ports that are used by RPC are not blocked by a firewall."(However this does not prevent the installation from continuing)The error logged in the GUI is:E2KExisting E2K3 Organisation is running in Summary: 2 item(s). 1 succeeded, 1 failed.

The routing group does not exist in AD after the failed installation.

It was unable to create the routing group because of what seems to be a bug - it was pointed to an E2K3 relay server and always looked for cn=1... However it should have been looking for cn=1. We pointed to another E2K3 server and the routing group is now installed.However still Exchange will not start and my end result is the same. I will try posting another forum post here with updated logs, in case anyone has comment.

We had this issue too, but with Exchange 2010. For us it was indeed replication as the error stated.repadmin / syncall on our DCs solved the issue.Mike Crowley: MCT, MCSE, MCTS, MCITP: Enterprise Administrator / Messaging Administrator
