ExBPA & Windows Server 2008
When I attempt to run the ExBPA from my Mailbox server role, ExBPA does not run against the CAS and Hub Transport servers. ExBPA states that it cannot contact the server. I have verified that the server is up, the Remote Registry and Server Service services are running. Also, "File and Printer Sharing for Microsoft Networks" is enabled.I suspect this is a firewall issue.Each Exchange server isrunning on Windows Server 2008. Any ideas?I obviously could run the ExBPA from each server, but it would be more ideal to just run the tool once and have it scan each server.

Hi, I think it could be a network related issue, please try to disable firewall between HUB CAS and Mailbox role, including Windows Firewall. If it is not the case, then please follow the steps below to narrow down the issue. 1. Please ensure that Microsoft Exchange Related services have all started. Note: You can find all the service here. Services Installed by Exchange Setup http://technet.microsoft.com/en-us/library/aa998342.aspx 2. Please use Netdiag from mailbox Server Note: You can find netdiag examples from the article below: Netdiag Examples http://technet.microsoft.com/en-us/library/cc782085.aspx 3. Please try to check event log to see if any error event has been logged there. You can post it here. If Exchange servers are working normally, then I suspect that something wrong with ExBPA. 1. First please use account which you use to install Exchange Server to run ExBPA. 2. Please post the exbpa report here. Regards, Xiu

Disabling the firewall did work. However, as a best security practice I'd rather not disable the firewall. What ports do I need to open for Exchange 2007? I thought Exchange 2007 opened all the necessary ports during installation.

Hi,The channel these roles use to communicate with each other is using RPC.Besides, I'd like to know if there's a firewall in front of all the Exchange Server roles. Which firewall has been deployed between these roles?Regards,Xiu
