Exchange 2010 SP2 Cluster Errors

Hello ,

I have setup a multirole enviroment with Exchange 2010 SP2 with DAG and i have some strange problems with ipconflict errors that SCOM gives me . My enviroment works just fine. I have test that DAG working correctly and mailflow is working .

Every 2-3 days i take errors from SCOM which i have for monitoring my environment. The first errors is about the file share witness resource that is not accessible by the cluster. Then that i have an IP address conflict for my DAG Virtual Address and that cluster ip address resource cannot be brought online because of duplicate IP address.

After 1 minute the whole thing works again flawlessly .

The thing is that im sure i dont have an IP address conflict.

Any ideas what to look for ?

Thanks

Is the DAG in the same site or span between sites ?
If you try to ping the concerned IP what information do you get from DNS ?

I would suggest you to run EXBPA and ensure all is good

Hello ,

DAG is in the same site . If i am try to ping the DAG Virtual IP i get the response times only . Is there something else for this ?

Thanks

There isnt but i would run EXBPA and check all is good and ensure that this IP isnt in DHCP if there is any ?

I dont have DHCP and the IP im sure is only used by the DAG ,

I also RUN EXBPA and the only problem i have is that the mailbox servers with the DAG are running over Hyper-V cluster and this is unsupported. I knew this thing from start but i dont know if this is the reason for the errors i take .
