I have a network that experiencing hardware issues last week. We believe it was a switch but are still piecing together what part of the LAN was affected. All connections have been restored and all machines can PING each other by IP but NONE of them can resolve a NetBios or DNS name.
I show DNS UP and running with out errors. I have reviewed the event log and found that all the Services have not had any recorded entries since the problem started 2/3/12. My network is not that clean...
While sitting on the server or client machine they can resolve themselves, but right now we are only operational because of IP to MAC.
address is: http://helpdesk.mycompany.com:nnnn
