DNS between diffrent forests

I have two forests that are at present only joined by a simple VPN, i can ping machines at each site via internal numbers.


How do i get dns to work in this situation

Forwarders for each others domains work partially but take out all the web servers.

is ther eany way of linking the two like you would with in the same forest?

Create a secondary zone on your server... point to the remote DNS server.

Create a secondary zone on the remote DNS server...  Point this to your DNS server as source.

Then updates your the DNS Suffixes of your clients and machines to include both forward lookup zones...

For example, if the zones are called:  yourdomain.local  and theremotedomain.local  you would add both of these dns suffixes to your clients and server.

Hi NJ,

Absolutely right, but is it gonna work in the case of AD integrated zones, and no cross-forest trust  (never used that config before) ?

Cheers

I had tried the zone transfer on secondary zone

which nearly works

there domain is corp.domain.com


when i do a zone transfer i get domain.com and thats populated, but the corp folder just has one entry (the DC  and it says ip unknown

Follow these instructions again...  the zone you want is corp.domain.com  (use the IP address of the DNS server for this forward lookup zone.)
