Connecting 2 DNS

[Cisco79]

hi all
finally we connected to branches of my company using WAN.
Now i have 2 domains everyone in single branch (xxx.com and other yyy.local)
managment doesnt wanna make trust between these domains, however, I can access all computers using the ip address but not using their names in other domain cuz no trust between two domains...
Now i wanna access all computers using their names , without doing a trust bet. 2 domains.
i guess this is a DNS issue in every domain..
anyone can help me or give me a hint what should i do??
thank you
stay cool

You could create a secondary lookup zone on your DNS server. Then use the remote DNS server as your source database. You will then get a copy of all the DNS records on the remote server. (Then do the same thing on the remote DNS server.)

You also should add the remote domains FQDN to your local clients domain suffix list (in TCP/IP properties). This can be done centrally through DHCP.

The reason this is needed is the following:

Example:
Your local domain is called: localdomain.com
The remote domain is called: remotedomain.com

By default your local clients all have a DNS suffix of localdomain.com

When ping is used or NSLOOKUP, the client will automatically append "localdomain.com" after the host name is provided. This allows yours clients to ping with just host name.

Client: Ping localconnectedhost <-- this will work fine
Client: Ping localconnectedhost.localdomain.com <-- this works fine

Client: Ping remotehost <- this will fail (unless you add additional DNS suffixes to each client) because "localdomain.com" is automatically appended. so, your reallying pinging remotehost.localdomain.com

However, if you add localdomain.com and remotedomain.com, these suffixes will automatically get appended when FQDN is not specified.

so the client will be able to just ping using host name in both domains..

-hope this helps...
