Cannot turn on Network Discovery RRS feed

  • Question

  • I have several Vista Pro workstations on a domain with a DC running Server 2008. When I view the Network and Sharing Center on the workstations, Network Discovery shows "Custom" with a green dot. If I try to switch it to "On", it will not switch.

    On the DC, I set the following in both the DC GPO and workstation GPO:

    Computer Configuration -->> Administrative Templates -->> Network -->> Link-Layer Topology Discovery -->> Turn on Mapper I/O (LLTDIO) driver

    Computer Configuration -->> Administrative Templates -->> Network -->> Link-Layer Topology Discovery -->> Turn on Responder (RSPNDR) driver

    All rules related File and Printer Sharing and Network Discovery are allowed in the DC firewall.

    Is there something else I can try at this point?

     

    This may be related:

    The workstations can connect to the server's shares and navigate through them (there are several). But when I attempt to copy a file to one of the local workstations, the copy starts but does not complete and I get a message:
    "Windows cannot access \\Server\Share
    Error code: 0x80070035
    The network path was not found."

    At that point, I lose network connectivity and have to restart to get it back.


    Any help is appreciated.

  • I reinstalled the OS on the Vista clients. That resolved the issue.
