This one stumps me- We recently made some minor changes to group policy (set intranet site for new WSUS server) and ran gpupdate on the PDC.
immediately after, a few workstations that are not joined to the domain stopped seeing the server via DNS. I can ping by IP address, but nothing I do lets those workgroup PCs browse to or connect to the server by name.
I've checked DNS on the server- it's functioning fine, , checked network settings on the affected workstations- zip. I can browse by IP, and file sharing etc is working, but DNS went poof.
from the server, I can not see the names of any of the clients or workstations in network neighborhood, even though they show up in the DNS server!
from the workstations, i can not contact the domain controller(i.e., try to join domain) or see it in the NN, but i can see all the other clients and workstations, both on the domain and off.
my gut says DNS problem, but where?
we use a router forDHCP- the server is the DNS, PDC and file shares.
