Hi All,

we have recently acquired a new business and need some advice on how to make them look and feel like us, as much as possible and what the limitations are around having two separate domains. i have configured the VPN tunnel , i have set up the trust and now need to configure the DNS setting what needs to be set up with regards to the DNS is it just the conditional forwarders. do i need to set up anything else?

am i able to link calendars and the GAL list so we can see these?

Thanks for any help,

For DNS you can use Conditional Forwarders, Stub Zones or Secondary Zones. Stub Zones are very similar to Conditional Forwarders, except they potentially require less maintenance. Secondary Zones are the most fault tolerant.

Setting up DNS name resolution will allow you to create a trust between the two domains / forests.

Calendars and GAL depend on the version(s) of Exchange you have deployed in each forest.

Thanks Chris, it looks like my issue is around the DNS not resolving correctly, what do i need to configure on the DNS from both sides. i tried the conditional forwarder but wasn't able to auth across the two domains and when validate the trust they couldn't see the opposite AD DC server.

im now trying to set up secondary Zone for both forward and reverse look ups  but they are unable to load the DNS server.
