Citrix Provisioned Server image is not starting after installing RES ONE Workspace on Microsoft Hyper-V Server

Version 1


    After installing RES ONE Workspace on a Microsoft OS with Citrix Provisioning Server the Citrix Provisioned image will not completely startup anymore. It will stop responding before the Ctrl+Alt+Delete screen should be displayed in the console of the Microsoft Hyper-V Server.

    The Microsoft Hyper-V based guest has two network cards configured (One Microsoft Legacy network adapter (legacy Hyper-V NIC) and one normal Network Microsoft Hyper-V Network adapter (synthetic NIC).




    During the boot process of the Machine, the default network adapter is changed.

    Originally, the default network adapter is the Microsoft Legacy Network adapter (Legacy Hyper-V NIC).

    This will be changed to the Microsoft Network Hyper-V adapter (Synthetic NIC), during the boot process. This is described in the following Citrix Doc article.



    This issue will be resolved in a future version of RES ONE Workspace.


    Choose one of the following workaround to solve this issue:

    Workaround 1:
    Replace the TDI based RES ONE Netguard driver with the WFP based RES ONE Workspace Netguard driver

    - First extract the driver from the MSI package of RES-ONE-Workspace-2016-SR1.msi (use 7zip or peazip to extract the MSI and afterwards the and copy the file netguard_amd64.sys (64-Bit Version), netguard.sys (32-Bit Version) or the RES Support engineer will provide you with a suitable version of the file.
    - Replace the file on the designated system in folder C:\windows\System32\Drivers  (32-bit system) and C:\Windows\SysWOW64\drivers (64-bit system)
    - Reboot the system

    Workaround 2:
    Disable the RES Netguard driver in the registry via the following setting and restart he machine:

    Key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RES NetGuard
    Value:   START
    Type:    REG_DWORD

    This only applies to environments where the RES ONE Workspace Network security is NOT in use.
