Home Directory - GPO mapping Vs AD Profile mapping RRS feed

  • Question

  • Looking for assistance with drive mappings applied via Group Policy Preferences & Home Drives.

    We have a GPO to apply drive mappings for the IT Department. This includes a mapping for the Home-Directory" (the H: drive). the format for this is \\servername\itusers

    The accounts for IT Users also had a Home-Directory mapping on the AD profile;again using H: drive, mapping in the format \\servername\itusers\username

    The GPO has been live since mid-June; the AD Profile mapping has been live for several years. On Monday, users reported that their H: drive mapping had switched from the \\servername\itusers\username mapping to the \\servername\itusers mapping. Nothing had changed on either the GPO or the AD profiles.

    We have resolved this by removing the mapping from the GPO (this had replicated drive-mappings from a login-script; we are migrating to GPO drive-mappings for Win7 compatibility). However, as we will be deploying GPOs to the other departments, I would like to know:

    1 - what is the order of applying drive-mappings regarding GPOs & AD profiles?

    2 - is there a tool/command/utility we can use to determine "effective" drive mappings? It would be doubly useful if we could determine if a mapping had been applied via GPO or via AD Profile, etc.

    Regards

  • Hi,

    1 - what is the order of applying drive-mappings regarding GPOs & AD profiles?

    The user profile is processed and then the script will run. IF the drive is mapped as H: using user profile the script should have error that drive letter is already in use. You can check the below link for GPO processing order.

    2- is there a tool/command/utility we can use to determine "effective" drive mappings? It would be doubly useful if we could determine if a mapping had been applied via GPO or via AD Profile, etc.

    You can try to enable USerenv logging and check the log file for the hints

    the process is as per the below link
