KB.921181 and "File Share Witness"

KB out yesterday (KB.921181) covers the introduction and details about the new “File Share Witness” quorum model. This is an improvement to the original MNS design that allows a read/write file share to serve as the “voter” for quorum status, eliminating the need for a third (or, at least, “odd-number”) node as voter. This new…

KB.867624 replaced

Looking for KB.867624? It’s been replaced and retired (and removed)… I had previously blogged about the “Upgrading to E2k3 SP2 on a cluster” process, and in that posting I had referenced the KB.867624 article about how to upgrade to E2k3 SP1 (pointing out that the process is essentially unchanged for SP2). But, someone brought to…

"Access Denied" creating an Exchange 2003 System Attendant resource

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!

Clustered Exchange setup tidbit

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…

Evicted your Exchange cluster node?

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…

Large Exchange 2003 clusters and disabling the MTA

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…
