Issue/Introduction

We're installing a Policy Server in folder D:\mydir\CA\siteminder on
Windows, and we'd like to know if the use of 8dot3name at creation
time is required as per documentation :

Enable 8dot3 Name Creation for the Windows File System

  Enable 8dot3 name creation for the disk volume if you want to install
  Policy Server and Administrative UI on the same machine and in the
  same non-default drive.

Is that mendatory to apply ? I have errors when I try to run fsutil
tool.

Environment

Policy Server 12.8SP3 on Windows 2016;
AdminUI 12.8SP3 on Windows 2016;

Resolution

This is required if you plan to install the AdminUI on the same
machine as Policy Server. This command not only affects the directory
and filenames, but also registry setting :

fsutil 8dot3name

  Queries or changes the settings for short name (8dot3 name)
  behavior, which includes:

  Scanning the specified directory path for registry keys that might
  be impacted if short names were stripped from the specified
  directory path.

As per documentation, you should disable it once installations are
done :

Enable 8dot3 Name Creation for the Windows File System

4.  After the installation is complete, you can disable 8dot3 name
    creation by executing the following command:

    fsutil 8dot3name set VolumePath 1

If you face a problem when running the fsutil command, make sure that
the

  HKLM\System\CurrentControlSet\Control\FileSystem\NtfsDisable8dot3NameCreation

is set to "2";

If you get the error "Access Denied" when running the "fsutil
8dot3name set VolumePath 1" command, then there's a way to bypass it
as explained in this KD :
