Cross Domain Name resolution question

I have a medium suized network with 4 physical locations and 2 domains (one for students, and one for teachers). i am running into difficulties occasionally when trying to ping by name from one domain to the other. I find that if I am at <machinea> and it is receiving it's DNS information from <Domaina.int> and I ping <machineb> who receives uit's DNS info from <domainb.domaina.int> I must fully qualify the machine name <machineb.domainb.domaina.int> in order to get a response.

While I have successfully worked around this issue by adding appending both suffixes in the DNS search order on my clients via a group policy; I cannot get over the nagging feeling that there is something amiss on my network.

Nope that is pretty much it, unless you tell clients to append the dns search suffix how would they know what it was? if it was left to them they could append with anything if you think about it? Even your default domain is appended but this is a default config as they are members of that domain.

Btw you can use group policy for this.
