Transaction Log Files and Designated Disk

Transaction log files filling up space causing mailbox stores to unmount.

1. Identify the designated drive which has low space caused by the transaction logs.
2. Cut/Copy log files (not any files that are res.log or .chk files) just cut/copy the ones in the middle of the directory to a file server, you may require user credentials if the file server is on a another domain.
3. Once copied check designated drive to ensure space has been created.
4. Open Exchange System Attendant and mount the mail stores, mounting each mail store will take a minute or so.
5. Ensure backup job is running on backup server.
6. Send test emails to ensure connectors are sending and receiving email with test user accounts.

To patch or not to patch

Well, didn't I get stuffed when following a routine patching exercise, applying the latest updates to secure Windows 2000 server had me awake for days, my insomnia had returned. So, after applying the patch Microsoft #KB931768 and actioning the usual reboot requirement, the server decides it wants to enter a continuous reboot loop.

Boot into safe mode? safe mode with networking? safe mode with command prompt? last known good? Pulling my hair out? Yes you've guessed it; the server wasn't having any of it. After 3 days of not knowing what to do, apart from the possibility of rebuilding or even upgrading to Windows Server 2003 and developing a small bald patch, I decided to have a good hunt around using my excellent googling skills for almost the entire weekend. I came across some excellent advice from techarena, it appears that quite a few of us who installed this patch on a Windows 2000 server had encountered the same problem.

The fix? Well, it does seem obvious, un-install the patch. Well I couldn't, more on this, later.

Use your Microsoft Windows Server 2000 CD and enter the recovery console.
Once at the recover console:
To uninstall hotfixes from the Recovery Console navigate to the hotfix's
spuninst directory and use the BATCH command to process the uninstall
routine. Example:

cd %systemroot%\$NtUninstallKBnnnnnn$\spuninst

then send the command:

batch spuninst.txt or spuninst.bat if the first command fails.

at this stage type in the following command:

expand d:\i386\sfc.dl_ c:\winnt\system32\ (d: assumption that it is your cd-rom drive)

Apparently the latest patch removes sfc.dl_ (now you should have recovered this with the previous step) Reboot............ Keep your fingers crossed.

hit f8 at start up then choose safe mode.
hopefully you should be able to boot up, once in safe mode, go to Add/Remove programs and un-install #KB931768.

As previously mentioned, I could not un-install the patch through the recovery console. I took a chance and expanded sfc.dl_ anyway and rebooted. Once in safe mode I was able to un-install the patch via Add/Remove programs.
