Enable 8.3 Naming Convention on Windows Server 2008 R2

I’ve cam across this while installing McAfee ePO 4.5, I got an error relating to it and here is how to resolve it using Windows registry.

  1. Go to start -> run
  2. Type Regedit
  3. Navigate to HKLM\SYSTEM\CurrentControlSet\Control\FileSystem
  4. Change the value on NtfsDisable8dot3NameCreation to 0
  5. Reboot the server

Nothing much to it eh =).

    Hi All, this is STILL an issue for the latest EPO creation now known as EASI_EPA. At 2gb its a beast to download and at the pre-req check it still throws up this “nuance” of 8.3 naming. You’d think two things by now;
    1) How is this not fixed or automatically resolvable (click to fix button would be super!)
    2) Why isnt this supported on Server 2012 yet?

    Hope this helps others, I’m having to bang in a virtual 2008R2 just for EPO. Meh, never was going to use that 2GB of RAM anyway!

    Have a great week!

    P.S. For a part time income thats not computers (I never take IT home!!) lookup topnotchliving.co.uk – i’m doing it, so could you!
