PowerShell Script for Recreating the Server Cache (related to error in Windows Event Log, Event ID 6482: Application Server Administration job failed for service instance Microsoft.Office.Server.Search.Administration.SearchServiceInstance)

Today I’ve had the error:

Application Server Administration job failed for service instance Microsoft.Office.Server.Search.Administration.SearchServiceInstance (150CA1DD-02E3-47C0-AA55-005A2927751F).

There is a nice article on Jeff DeVerter’s blog:

I had to clean up lots of servers. Because of that I’ve created a little PowerShell script.

The script will automatically process all steps descripted by the KB article, Chaitu Madala and Jeff.

You can execute the script on every server.

If your receive a yellow message at the end of the process that the resulting “cache.ini” file is diffrent from the original one. I think the cache.ini file contains a timestamp and it is OK if the new timestamp value is greater than the original one… But you use the script at your own rist – as always.
