We just upgraded to Exchange 2010 and I'm trying to explore the ECP. I try to log into it by going to https://mailserver.domain.com/ecp - it takes me to the OWA login, I type in my credentials, then it spits out an error: Unexpected Error An error occurred and your request couldn't be completed. Please try again. Can anybody point me in the right direction to troubleshoot this? Does ECP need to be enabled in EMC or something? ----------- Ron E Biggs Network Administrator Entertainment Studios

Ensure you have correctly configured the InternalURL & ExternalURL URLs for the OWA and ECP virtual directories. Set-EcpVirtualDirectory and set-OwaVirtualDirectory

Well I checked the EMC for the virtual directories of both OWA and ECP, and they both show up as expected: InternalURLs are https://mailserver.domain.com/owa and https://mailserver.domain.com/ecp. I tried a couple tweaks, like adding an identical ExternalURL in EMC, changing the login method for ECP, and logging in from IE (within the domain). No dice, same error. Not really hip on using Shell if the same thing can be done on EMC. Which I assume I just did.----------- Ron E Biggs Network Administrator Entertainment Studios

Can you access it via OWA from the Options menu? Are you using an account that is mailbox-enabled and located on the Exchange 2010 server? Did anyone mess with URL redirection? Any errors in the event logs? What SP and RU is Exchange 2010?

Can't access from the OWA options menu either. Account is mailbox enabled, on the server, nobody messed with URL redirect. It's Exch2010 SP1.

BOOM SHAKALA! It worked! For the record, I went in through CMD as Administrator, navigated to C:\windows\system32, and ran lodctr /r. Then did an IISreset. This rebuilds the performance counter from a backup store. Thanks so much.----------- Ron E Biggs Network Administrator Entertainment Studios
