The local DC and all remote DCs are up and accessible. The server is registered in DNS. IPv6 is enabled. The server has only 1 NIC and a static IP. It's a VM on EXS 4.1. There is no AV software installed. The same set of GP settings applies to the production HT/CAS and DR HT/CAS. Windows OS is fully patched. All Exchange prerequisites for Windows 2008 R2 have been installed as per http://technet.microsoft.com/en-us/library/bb691354.aspx. I'm running the installation under an account which is Domain/Enterprise/Schema admin.
The production Exchange servers run without any issues. There are 30 servers on the DR site (DC/apps/DBs/backup etc) and they all run without any issues.
Any idea?
Thanks
