I'm in a process of implementing two node DAG accross two sites. I have installed second exchange server at my active directory site.
Site A - 172.16.1.X , DC- 172.16.1.8 Windows 2008 R2
EXCHN1 - 172.16.1.9 - Windows 2008 R2 SP1 with Ex 2010 Sp1
Site B - 172.16.8.X , ADC - 172.16.7.8 - Windows 2003 sp2,
EXCHN2 - 172.16.1.9 - Windows 2008 R2 Sp1 with Ex 2010 Sp1
Now the problems facing are
1. Getting a warning message when creating a new dag 'The Exchange Trusted Subsystem is not a member of the local Administrators group on specified witness server <ServerName>. I have added exchange trusted subsystem to local administrators group in witness server. But still same error
2. When trying to add second node to DAG , the wizard failing with an error message(svreen shot attached) 'A Server side database availability group administrative operation failed. Error the operation failed. Create cluster errors may result from incorrectly configured static addresses. Error: An error occurred while attempting a cluster operation Error Cluster API "Add clusternode()(max percentage 100)failed with 0x5b4. Error: This operation returned because the time out period expired"" failed [server: exchn1.mydomain.local]'
I tried removing and reinstalling failover clustering feature on my second node. but still same issue. Awaiting for valuable suggections to resolve this error
