got a pc that has been up and running for a couple of years that is not resolving dns names intermittently, like my server.  can ping the server ip fine but cant ping the server name.  netbios is on, firewall is off.  when i go to network->entire network" only the local computers on the lan show up.  the server is on the wan.  checked ipconfig /all and the dns settings are right.  did a ipconfig /flushdns and still does not work.  not sure what else to check.  its only effecting this one computer on the lan.

    drop machine from domain and rejoin should work

    better than drop it down from domain and back should be reset computer account in AD.
    You can also try to boot in safe mode and check it it´s better or the same.
    If safe mode is working, than probably it´s some virus or malware - if so, check items which are running after PC boots (msconfig), check task manager running processes and google for unknown, also make a AV and malware scan

    If it is running windows vista or 7 try checking the Advanced network sharing settings for the Domain profile. Check to see and make sure that Network Discovery and File and Printer sharing is on.

    I reset account, checked for virues. no go.  so i left domain then when i went to rejoin it could not see the domain controller.  so i gave the pc a static ip and all is well.  at least for now.

    ok I just noticed that the DHCP server for that LAN, that is managed by my ISP, was not handing out a WINS ip.  They recently were working on their router and removed that piece from the DHCP settings.  i did not notice this when I checked the ip settings before.  Thank you for trying to help me though!
