KB.906906 talks about another problem you may run into while creating a system attendant resource for Exchange 2003 cluster, relating to Remote Registry access/permissions. This is really just pulling out the “Symptom #4” part of KB.329229 as its own KB article, but it’s still worth pointing out in case you run into it!

Techweb reports that there’s an exploit out for the MSDTC security fix in MS05–051. So, if you’re running an Exchange cluster on Windows 2000 server, you’ll want to get this patch applied ASAP!  See the security bulletin for more details, and for info on the status of other Windows versions.

Great news! The long-awaited ability to use “standby” Exchange clusters is finally completed testing and documentation with its addition to the Disaster Recovery Operations Guide: http://www.microsoft.com/technet/prodtechnol/exchange/guides/DROpsGuide/2493c2d6-618c-4c49-9cb1-fff556926707.mspx This is one of those topics that has come up again and again over the years, and there was never any good (supported) solution for it. Well, over the past…

This question came up yesterday on a list I read, so I figured it might be of interest out here. Do you remember the “Setup Shall Install the Clustered Version of Exchange” pop-up in Exchange 2000? This was the pop-up you’d get when installing the binaries for Exchange 2000 onto a server that was joined…

Jim McBee recounts a recent experience with this, and how forgetting to do a “setup /reinstall” on the cluster node led to Exchange thinking it was a beta/evaluation version of Exchange. Excellent point to make: if you ever evict one of the (Exchange binary) nodes from the Exchange cluster, make sure you either reload the whole…

Big revision recently to KB.810489. This is the KB that talks about the MTA function and how it can or can’t be disabled in various scenarios. The core change is that if you’ve got super-large Exchange clusters (>4 nodes) in a native-mode administrative group (and do don’t have MTA-dependent foreign connectors, etc), you may want…

This is a bit of a specific topic, as it only affects people who are trying to use the MTA in their cluster (for mail delivery back to 5.5 in mixed-mode, or to foreign systems not connected with SMTP, etc) *AND* have >4 nodes in their cluster. There’s a new KB out that will help…

Rod posts today about the strange (and sometimes frustrating) behavior where outbound SMTP connections from an Exchange cluster originate from the host IP address rather than from the virtualized IP resource associated with the Exchange Virtual Server. Great post and this is a common question on the newsgroups, etc. Scott Landry also talked about the technical…

KB article came out the other day on this sort of obscure scenario, but interesting to know about in any case: KB.896617: “The Exchange Information Store service stops responding when the Exchange Information Store service is shutting down or the Exchange Cluster server is performing a failover process”. Couple of things to note: This only…

I blogged about KB.898364 briefly when it was created, but over this past weekend there was a flurry of newsgroup posts about putting clustered Exchange onto cluster nodes that are also domain controllers. Several responses referenced KB.281662 (how to cluster AD domain controllers), which didn’t very clearly specify not to do this with Exchange. That’s…
