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.
