Exchange 2007 - Which Version am I running?
Posted on 2009-02-23
First of all, our Exchange Server seams to be running smoothly, so this is no issue that requires immediate attention. Still, I'm kind of confused about all the version numbers I found today.
Like a good admin is supposed to, I'm trying to keep my servers as up to date as possible. Today I installed the Exchange 2007 SP 1 Rollup Update 6, released on February 10th by MS. We have only one Exchange Server, which has all three roles (Mailbox, Hub Transport, Client Access) and is also the OWA server. The virtual machine (VmWare ESX 3.5) is running Windows Server 2008 Std x64. We do not run an Edge Server.
The update took a while to install (40 minutes or so), but completed successfully. I only was a bit confused by two things during the install.
First: The service Microsoft Exchange Information Store never actually stopped. The status was "Stopping" during the whole update and even after it finished, the status was still "Stopping". Store.exe was always active in the Task Manager, but hardly produced any CPU load. However, I wondered how the MsiInstaller is able to update the Store.exe if it was always running during the update procedure.
Second: I found some (like 20) events in the Application Log. They're "Informations", not warnings or even errors, but they're still a bit concerning: "Product: Microsoft Exchange Server. The file D:\Exchange Server\Bin\store.exe is being used by the following process: Name: store , Id 2256."
So I started digging a little and I found no less than four different versions without actually digging that deep. Note that these are all on the very same machine:
1. & 2. In OWA, under Options / About, I found "Outlook Web Access version: 8.1.340.0", but "Mailbox server Microsoft Exchange version: 188.8.131.52".
3. In the Exchange Management console under Help / About, the version is 8.1.336
4. The fileversion of store.exe is 8.1.338
Is it possible that the rollup update only updated parts of my installation? But which version is actually running? How do I get them all to the same version? Or is that not necessary at all?
And: can anyone check his versions of those four things and post them here?
Any help and ideas are appreciated.
