Re: split zones not resolving correctly intermittently...

Thanks for the reply Kevin! This would make sense on a laptop user but this
has happened to a few desktop users. The DNS is resolving
citrix.companyname.com to the external ip address instead of using the local
zone I created on the DNS server.

.... just checked the server's TCP/IP properties and maybe this might be the
problem. I have the Preferred DNS server pointing to itself. The Alternate
DNS server is pointing to another AD/DNS server at a different location.
This server resolves citrix.companyname.com with the external ip address.

When does domain name gets resolved by the Alternate DNS server? What would
happen if I remove this ip address? This is on an Active Directory server
that's replicating with 15 other ADs.

Thanks!

I running Windows 2003 Active Directly/DNS in the office with the
following zones:

zone: companyname.local (for the local domain)
zone: citrix.companyname.com (server is hosted locally)

The companyname.com is hosted on our ISP.

If a user connect to this citrix.companyname.com while inside the
office, the DNS resolved to 192.168.1.254. If they are outside the
office, it
12.12.12.12, (as an example).

The problem I started to notices is that intermittently the user gets
the
12.12.12.12 while inside the office. The fix is always get them to
release/renew their ip address or a reboot. Afterward, it would
resolve correctly with the 192.168.1.254 address.

My question is what's wrong and how to fix this problem.

Either the client is still using an external DNS address, or the TTL on the
public side record is too long for the situation. See about reducing the TTL
to 15-20 minutes on the public DNS.
