DNS for a subdomain

Hi All,

My company uses a sub domain for a satellite office, all works fine and replication takes places etc etc.

The problem I had was with DNS.  I’m based in Contoso.local and I cannot ping any device the sub-domain Sub.contoso.local without fully qualifying the domain.

For example if I ping a server1 on the subdomain using

DNS cannot route the command where as if I type

it works fine.

I’ve checked DNS on Contoso.local and there are conditional forwarders to Sub.contoso.local:

DNS_Issue

So how can I get around this??  The answer is to add a DNS Suffix locally or to all the domain devices via group policy:

Group policy:

Computer Policy > Policies > Administrative Templates > Network/DNS Client > DNS Suffix Search List.

DNS_Issue_GP_Suffix

Then GPUPDATE /force your client and run IPCONFIG /ALL and you should see:

DNS_Issue_IPCONFIG
