Hi guys,
I'm hoping for a bit of assistance. I have stepped into an environment where there is one production Exchange 2010 server and one Exchange 2013 server. The Exchange 2013 server is in a unrecoverable state however it contains the domain administrators mailbox and therefore I cannot remove it manually. As it was a vm, I took it offline, created an identical server (name, os version(Windows 2008 R2 with latest updates), ip address etc.), installed all the prerequisite components and then ran setup /m:RecoverServer /IAcceptExchangeServerLicenseTerms. Everything runs through successfully until it gets to the Mailbox role: Transport service where it fails with "Unable to set shared config DC.". After some searching on Google, it suggests that ipv6 is disabled on the DC. We have two DC's in our environment and both have ipv6 enabled as does the exchange server. If I try to re-run the installation for the role alone, i.e. Setup /mode:install /IAcceptExchangeServerLicenseTerms /role:HubTransport, it fails with "The machine is not configured for installing "BridgeheadRole" Datacenter Role."
Any help would be greatly appreciated.
