  • Network Policy Server role installation failed

    we have Windows 2008 R2 x64 with the roles DC, DHCP, DNS, File and Remote desktop services.
    We had also the Network Policy Server installed but after service start failed we try to reinstall it.
    When we try to install the role "Network Policy Server" we get an error:

    "Attempt to install Network Policy Server failed with error code 0x80070643. Fatal error during installation."

    In the administrative events we get an error:

    "The Network Policy Server server terminated with the following error: %%-2147352573"

    No other Event entries.

    - We already change the VSS Settings in Registry "Permissions on VSS-DIAG"
    - NT-Authority\NetworkService the value is already 1

    Have somebody an idea or solution?

    Thanks and BR

    Do you not think too many roles on one server? Have you tried install NPS on a different server just to be sure.
