Hi Experts.
We have an three Node Exchange 2003 Cluster.
Once a week one of the ressources are not available, the users are communicating that Outlook will not connecting the Exchange Server.
Showing the Cluster Administrator, all of the ressources are all up and running.

First I had the look on the storage box, controlled all versions to be at recommended versions supported by the manufacturer. I have found some signs that the transactions logs could not be written. Now we are shure that the versions of the storage related software and drivers are correct.

I'm now occupied to merge all the concerning events into one overview.

I'm not very familiar with a Clustered Exchange environment. Can anyone please help me to analyse and resolve that problem. Is there a way to log what's going wrong and find some hints?

Some details about the environment:
3 Nodes
Windows Server 2003 SP1
Exchange Server 2003 SP2
2 Virtual Servers Active/Active
This is an environment with approximate 100 Exchange Servers in as much routing groups

Please excuse my bad english.
Thanks in advance for your help

Is this environment Active/Active OR Active/Active/Passive?  I used to run a 3 node Exchange cluster Active/Active and ran into similar issues.  I would recommend making on node passive if this is the case.

I'm not shure if I understand it right, so I will give you the details; I have following Ressources:
Exchange Virtual Server 1 (normally active on physical node 1)
Exchange Virtual Server 2 (normally active on physical node 2)
MSDTC (normally on physical node 3)
Quorum (normally on physical node 3)

Is this Active/Active oder Active/Active/Passiv? As I say - not familiar

In addition I have found that the Antivirus ServerProtect had scanned the mailroot directory. although ServerProtect is configured to only scan local Drives.
I will uninstall ServerProtect this night

Thanks

On a 3 node cluster run everything on 2 nodes and forget the 3rd.


Here is a good artcile about the reasoning.
