MS DTC fails on 2003 exchange cluster
I am trying to readd a node to an Exchange 2003 cluster. After adding the node, I try to install Exchange 2003. When I try to install Exchange, I get a message saying that it can't install Exchange System Administration since MS DTC is not running in the cluster. So, I try to create the resource, add its dependencies, bring it online, and it fails. I tried to add it through the command line, and I see when I add the Quorum as a dependency, I get this message:
C:\Documents and Settings\m>cluster clustername res "MSDTC Res
ource" /ADDDEP:"Quorum_Q"
System error 1722 has occurred (0x000006ba).
The RPC server is unavailable.
I verified the RPC server is running on both servers. I have the following messages in event viewer (please see attached)
Any advice would be appreciated.

No. It's with the other resources. FYI, this is how it ran prior to evicting the node. Also, that KB has the following entry for Exchange:
if you have a light-use DTC scenario such as a cluster dedicated to Exchange Server, proceed and use the Cluster group. On dedicated Exchange Server clusters, the MS DTC resource should be placed in the default cluster group.

Is it a problem for you to configure in separate RG ? If it installs and works then it is work round. I personally have always configured in separate RG.

It isn't a problem; I was just trying to set it up the same way it was before.
When I get to this part, I'm not sure what to enter:
In TCP/IP Address Parameters, select the public network, type the unique static IP address for MS DTC, and then click Next.
I'm guessing I need to request a static IP for this?

Yes you will need a static IP, since it doesn't actually do much there is no need to register in DNS.

I'm in the process of following the KB and I'm at:
Create a "Physical disk" resource.
Note You may already have a physical disk resource created. If so, you will have to move this physical disk resource into the MS DTC group and go to the next step.
I have a physical disk for the quorum, Exchange_data, and Exchange_logs. Do I need to move all physical disks to the MSDTC group or just the quorum?
What will happen if I move these items to this group while they are online?

I think this is referring to s SEPARATE physical disk resource - eg a small LUN which you can allocate to the MSDTC resource ? If you are using the same resource then you are back at square one.
Do you want to use a separete disk resource for the MSDTC as I usually do, or do you want us to try to troubleshoot your original issue ?
I would also recommend you download and install the Cluster Diagnortics Tool, as this can give you a very easy way to troubleshoot cluster issues :-

I found the problem; however, I'm unable to reference the fix until I get back to work.
What I can say is there is a registry entry for the cluster that indicates whether MS DTC is running in a clustered state or not. If the value is anything other than 1, then MS DTC won't run. I changed the value to 1 for both nodes, started MS DTC on the active node, and it is now running. I was also able to run this resource with all the other resources in the cluster. I'll post the link when I return to work.

Well done - glad you found fix !!

That is strange since the article applies to products no longer supported ?

Ah - thanks for clearing that up !
