DNS - 2 subnets, 2 domains ... DNS not transferring to each other
Hello !
I've got two small companies, each with their own subnets. CompanyA is on 10.10.1.0 and CompanyB is on 192.2.900.0. A Windows RRAS dual nic computer is acting as a router between the two. Each subnet can ping each others computers.
The problem is with DNS. I would like to have CompanyB DNS listed as a Secondary zone and vice versa. I have checked the Zone Transfer to any server, on both DNS servers.
However, when the Secondary Zone is added, DNS reports that 'the transfer of the zone from teh master server failed', with the DNS server recieving the 'red cross' treatment !
Do I need to do anything special to allow DNS traffic over the router ? It's odd that the two DNS servers can PING each other, but cannot transfer data. I'm sure I've allowed all permissions.
Thanks,
S.S.

The connection between the 2 subnets is just a Windows 2003 RRAS (brand new install - nothing 'special' configed) ... both on Ethernet ... companyA is on this floor, CompanyB is below me :) ... so nothing too complex going on ... the W2003 box is just a dual-nic card which passes traffic between it. (shares etc)
I guess if you are saying the nothing special needs to be open, then I *must* of set up something badly on the DNS Servers themselves.
Hmmmm.

I don't believe this - it's started working ...
I restarted all the DNS servers and they've all started talking to one another !
Have some points for reassuring me it wasn't a firewall thing.

Which media are you using to connect these two subnets.? any broadband, dial-up ?
There is nothing to do with Router as far i know....this might have happen if you are using a firewall and didn't open port for replication between these two DNS servers.
Let us know.
