We want to build Exchange DAG with three physical servers. First server is use for 2008 R2 AD domain controller, and others are installed Exchange 2010 standard server.
After we created DAG and CAS array, database replication is working fine. External Outlook users failed to connect to secondary exchange server by use rpc/http. But able to connect to primary server. Outlook keep asking input password.
When doing testing Http Authentication Methods for URL
https://server1.mydomain.com/rpc/rpcproxy.dll , it show blank screen after i enter password.But for server2 testing, it redirect me to OWA webmail page.
Setting of Rpc virtual folder in IIS of two servers is same, that is redirect to "https://mail.mydomain.com/owa", but do not know why server2 not response as same as server1. From server2 windows event viewer, there is no event id 4 which indicate rpc/http is load into iis. But event id 4 can be found from server1. I guess the problem may be caused by damaged rpc/http component, thus i tried remove and reinstall rpc/http component. But still not luck.
When doing Get-TestOutlookConnectivity at server2, the rpc/http is failure.
Any idea how can i fix this problem?
