Can't ping DC after DCPROMO

Installed an additional server on our system to run mainly as backup storage. Prior to running DCPROMO on it, I could ping this server from any other location on the domain. After running DCPROMO I can't ping it.
It has 2 NICS which I have both to static and input the gateway and DNS details.

Any clues as to what the problem might be?

Wondering whether to demote it again, or if there was any point in promoting it in the first place.

Hello paulmac110,
Do you ping servers IP or servers name?
Generally you should run netdiag and dcdiag from elevated command prompt.

Ping servers IP address and server name, pings time out on both .

Can run dcdiag on the problem server and post you a report. Can't run Netdiag though????

Two things.
firstly DCPromo only when you need to add an additional Domain Controller to your network, otherwise (in my opinion) it's not required.
The ping issue could potentially be windows firewall, check in your control panel and either disable or make rules to allow ICMP through.

Hi,

DCPromo has a habit of reverting the DNS and pointing the DNS back to itself (loopback address - 127.0.0.0)

Please check whether this causing the issue.

Hope that helps :)
