I have 2 domains
lets call domain 1 homeoffice
lets call domain 2 remotelocation

When i'm at the home office which is on homeoffice domain and setting up a new computer, is it possible to have it join remotelocation domain instead?

I can ping the remote locations computers and i can even use the ip\c$ command.

when i try to join the domain it can not find the domain controller.

I have admin rights on both domains, but usually have to go onsite to join the domain. Is there a way to avoid this and if so can detailed instructions be given please?

In order to join a pc to the domain you will need to add the DNS servers of the domain you are joining to your clinet. Once you can do name resolution then you can add the machine to the domain.

Joining domain relies on DNS to find the DCs.

I think you have site to site reachablity to the remote domain.

Please set the windows 7 DNS to the remote server, do a nslookup to make sure the remote domains are reachable and then join the workstation the remote domain, I did it many time and it works.

Thanks.

Okay here is what I have done and i can't get it to work
lets say my domain home office ip for the domain controller  is 15.x.x.100  and its name is hoad
when i added the remote locations domain controler ip of 16.x.x.250 i can still ping and connect with administrative share but when i do nslookup i get the following
hoad.homeoffice.local can't find 16.x.x.250 non-existant domain.

What am i doing wrong?

Its not Domain Controllers IP, rather the DNS IP.
DNS could be on a different server that the DC.

I'm hearing you but not understanding you.
if the domain is remotepc.local and it resolves to the x.x.x.250 address wouldn't that be the domain controller?

say for example i want to go to bbmis.local and its 12.2.2.250 wouldn't i add that to the dns entry. Sorry confused but trying to understand.
Thanks!

For most environment internal DNS is usually hosted on the Domain Controllers as well. This is because DC's rely on DNS for name resolution to provide authentication.

When you refer to DC's they are most likely DNS servers as well. If your enivornment is not setup this way and your DNS servers are separate from your domain controllers then you need to add the DNS IP addresses into your Win7 clinet machine.

If you do nslookup <domain.com>

This will provide you all of the DNS IP's that you can use for your Win7 client. Really you only need to specifiy 1 but if you have more then 1 DNS server you can add multiples to the Win7 client.

If you remote into a machine in the other domain then open up the command prompt and type ipconfig /all and see what DNS servers are being used. From there you can go back to your workstation and enter them in. I am wondering if you are getting reply backs from your local router which is giving you mis-information.
