[sydborn]

Hi,

 

Please How do I health check my dns in server 2012r2?

 

The IP address on my computer is different from that recorded on the DNS record?

 

flushing the dns on the computer isn't working

Hi,

 

Open a cmd prompt on a networked pc, ideally ping a server or pc with static ip to start with and make sure you get a response. if you do then use nslookup "ipaddress" if you see the correct hostname (you should as its got a static ip) then the next step is to do the reverse i.e nslookup hostname and check you get the correct ip back. if this worked then DNS is in working order. The next step is to ensue scavenging is enabled. Take a look at https://technet.microsoft.com/en-us/library/cc771677.aspx and https://technet.microsoft.com/en-us/library/cc753217(v=ws.11).aspx

 

Scavenging won't work immediately you need to let run but it does work and do its job.
