New Windows 2008 R2 DC can't be pinged or browsed

Posted on 2012-12-26
Last Modified: 2016-11-23
I have a weird issue. Added a new Windows 2008 R2 domain controller and another Windows 2008 R2 file server both on same subnet. From a second subnet I can ping the file server but not the DC. From the DC I can surf the web so I know it has network connectivity. Attached is a rough diagram of the connections. From the servers gateway (Dell Powerconnect 6224) I can ping both servers and the machines on the other subnet. These machines are on another "LAN" on another floor. The floors are connected to each other from one Powerconnect 6224 to a second both acting as the gateway for their respective networks. I have the firewall off on the DC not sure what I am missing.

Thanks in advance!

Check if Network discovery is turned on...if not, turn it on

Actually, keep turning it on but when I go back to look it is turned off. This happens on both the new DC and fileserver.

Is your firewall managed by a 3rd party application?
