I have strange problem in my networkHere is the topologyRemote Office -----Internet VPN tunel -----Local OfficeWindows 2008 server -Linux router -----Internet VPN tunel---ISA Server ----Windows 2008 serverAt remote site3 different network card with 3 different Networks on Same Server1. 192.168.30.0/24 routed to Local Office2.10.10.0.0/16 -My storage network3.11.11.0.0/16 -HeartBeat4.DNS Server (Domain Controller)- 192.168.30.231 DNS name -srv.etx.local5.Domain - ext.localThe networks 10.10.0.0 and 11.11.0.0 has no routing enabled to other officeAt local Office1 inside network1.10.7.12.0/242.DNS Server (Domain Controller) - 10.7.12.250 DNS name -srv2.in.local3.Domain in.localI have no problem pinging from 10.7.12.0 to 192.168.30.0 and back.At local officeon my DNS server a had added Conditional Forwarder to Domain: ext.local - IP address 192.168.30.231At my local office from srv2.in.local i try to test my connection.Pingfrom 10.7.12.250(local office server) to 192.168.30.231 (remote office server) works fine ,but when i tryto resolv DNS name to IP i havestrange problems.Here is an example of how i test connection and what returs DNS server.nslookup srv.ext.localNon-authoritative answer:Name: srv.ext.localAddresses: 192.168.30.231, 11.11.11.231, 10.10.10.231So my remote server replies with 3 different addresses which are binded to the 3 different network cardWhen i try ti ping server by namePing srv.ext.localPinging srv.ext.local [10.10.10.231] with 32 bytes of data:It returns me an address from network 10.10.10.231 to which i do not have routingAfter hours of reading and testing a found that DNS server uses netmask ordering to return the closest address to client network.I try to disable Netmask Ordering in Both DNS servers but my DNS server still returns address 10.10.10.231.Is there any way to resolv this issue ?We had tryed to reorder Adapters and Bindings but the problem continuesI had try to make Primary DNS zone at my server and copy records from remote server but when DNS records are changed i have to do it manualy every time ;)I want to do dynamic updates not manual .The seccond solution that may work but not tested is to change 10.10.0.0 network to 192.168.31.0 and DNS server than maybe return me the closest address 192.168.30.231 .

Hello, Accrording to the result of nslookup, I find all the 3 different Network cards of the remote server have registered their IP addresses to the DNS server srv.etx.local in the remote site. 1. Can you please check if you have made all the 3 network connections point to the DNS server srv.etx.local? If so, please remote them in the network connections properties to disable DNS registration for the following network. 10.10.0.0/16 - My storage network 11.11.0.0/16- HeartBeat network If possible, you can use IP address or host file to access the server in these disconnected networks. 2. Also, please open the DNS management console on the host srv.etx.local, and then remove the A records of the srv.etx.local with the 2 IP addresses (11.11.11.231, 10.10.10.231). And then click "Clear cache" on srv.etx.local and run "ipconfig /flushdns" and then run "ipconfig /registerdns" on the DNS server in the remote site. 3. On the local site, please find another client to run "ipconfig /flushdns" first and then try to ping srv.etx.local to check if the issue still exists. Hope it helps.Your potential. Our passion.

Hello ,I have done it and works fine but thats is not an option because Internal networks 10.10.0.0 and 11.11.0.0 must be registered in DNS server .So i found another solution.After hours of reading and googleing i found that my only problem is DNS mask ordering and network priority.I change networks form 10.10.0.0 and 11.11.0.0 to 192.168.51.X/25 and now DNS server return to me the closest address to my network which is 192.168.30.0 Now everithyng works fine.There's maybe another solution but at my case i can't delete record from my DNS because they are needed.
