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:

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

Jeff references to this articles:

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.

  1. This was the last piece of automation I needed so all of my featurereceivers executed cleanly — Thank you!

  2. Hi,

    Line for needs to have backslashes in order for the script to concatonate the cache folder root together. Thanks for putting it together!

  3. Line four should be as follows – hope this helps someone:

    $cacheFolderRoot = Join-Path ${env:ProgramData} “Microsoft\SharePoint\Config”

    Thanks for the nice script.

  4. Amazing Script!!, What i have to do if i get the message “MAYBE an error occured. the content of the cache file….”

  5. Check for admin rights, required for service stop/start:
    Write-Host “Checking for admin rights” -ForegroundColor green
    If (-NOT ([Security.Principal.WindowsPrincipal] [Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole] “Administrator”))
    {
    Write-Warning “You do not have Administrator rights to run this script! Please re-run this script as an Administrator!”
    return
    }

  6. For multiple folders, just took the last one:

    $mostRecent = 0
    $cacheFolder | % { if ($_.LastWriteTime -gt $mostRecent) {
    $mostRecent = $_.LastWriteTime
    $cacheFolder0 = $_.FullName
    write-host $cacheFolder0
    }}

    if( $cacheFolder -ne $null) {
    #$cacheFolder0 = $cacheFolder[0].FullName
