Cannot see network nodes in Win2K8r2 server for an isolated LAN workgroup labeled unidentified (public) network
Posted on 2012-03-25
Problem: When clicking network to see the network nodes or computers on a Workgroup, all of a sudden cannot see the network nodes. Network and sharing calls this an unidentified network and public (although this is an isolate network NOT connected to another LAN or internet; however the IP space is a public type).
It was recently able to see the network nodes.
Computer browsing service is turned on, firewall is turned off, this server is in a workgroup, it has recently been set to be the DHCP server (DNS and WINS also running with DNS and WINS scope options added to DHCP). Static IP set for server, it is also the DNS and WINS server. No default gateway set (because it is isolate network/workgroup)(On another similar isolated network, these same steps did not lead to losing view network nodes). Can still UNC to other nodes, but cannot not see the network nodes.
Added note, did see one on-line suggestion that a third party install may effect the viewing of the network neighborhood. One install that I had done between viewability of the Network nodes, and non-viewability today, was a McAfee install on this server. So I uninstalled McAfee, rebooted, and now the nodes are back. (I had rebooted earlier with no such success). Also noted that an _MBrowse_ node name in WINS records was released or tombstoned, and is now active again, after this latest reboot following the McAfee uninstall. Reinstalling McAfee now to see if the network nodes disappear from viewability again. Have no clue if McAfee and node viewability is truly correlated (on a different isolated network, nodes did not lose viewability after the McAfee install).
Thanks in advance for any ideas.
