I have followed this article-- http://technet.microsoft.com/en-us/library/ff923256.aspx --to set up redirected Autodiscover for multi-tenant Exchange 2010 SP2 (not using /Hosting). After doing so, EMC and EMS launch normally when run on the server itself. But when run remotely, EMC posts this message when I click on the Microsoft Exchange On-Premises node: ----------------------------- Initialization Failed The following error occurred while attempting to connect to the specified Exchange server 'server.domain.local': The attempt to connect to http://server.domain.local/Powershell using "Kerberos" authentication failed: Connecting to remote server failed with the following error message: The WinRM client set a request to an HTTP server and got a response saying the requested HTTP URL was not available. This is usually returned by a HTTP server that does not support the WS-Management protocol. For more information, see the about_Remote_Troubleshooting Help topic. Click here to retry. ----------------------------- EMS posts this similar message when launched remotely: [server.domain.local] Connecting to remote server failed with the following error message : The WinRM client sent a request to an HTTP server and got a response saying the requested HTTP URL was not available. This is usually returned by a HTTP server that does not support the WS-Management protocol. For more information, see the about_Remote_Troubleshooting Help topic. + CategoryInfo : OpenError: (System.Manageme....RemoteRunspace:RemoteRunspace) [], PSRemotingTransportException + FullyQualifiedErrorId : PSSessionOpenFailed Failed to connect to an Exchange server in the current site. Enter the server FQDN where you want to connect.: ----------------------------- If I stop the "Autodiscover Redirect" web site, remote EMC & EMS work correctly. So it appears that the connections are ending up at the "Autodiscover Redirection" web site instead of "Default Web Site". How do I prevent that? I've reviewed all the steps in the article, and believe I have done exactly what it said...or rather, what was intended; it's a pretty mangled TechNet article. TIA
