Join test domain name on ISE

[hientruong80]

we already have AD-1 (production network) in ISE. We want to add and join other AD-test (on test network) but DNS server of test and prod will never be configured to communicate with each other and these DNS server can not have DNS entry for both the AD's in order for them to communicate with each other (no trust etc). Please let me know if you get some way to make it work beside of  all DNS servers must be able to resolve DNS queries for all domains.

Thanks in advance.

The ISE server(s) can have multiple DNS servers configured so simply add one from production and one from test.

Like Marvin say, you could enter multiple different DNS servers in ISE, alternatively, the DNS server in prod doesn't need to communicate with test, but you could just configure a forwarder for the test domain on the prod DNS server, no trust is needed
