DNS Issue

[bicyleman9008]

We have an SBS 2003 server that is named mycompany.office.dns.
The company website is

http://www.mycompany.com.

The latter does not resolve to its IP address properly.
The local user cannot access

http://www.mycompany.com

from PCs on the local network.
For the longest while it did work fine, however.

The tempory fix was to put MX and A records into the local DNS that points to

http://www.mycompany.com.

Now I want to try to fix the problem properly.
What could cause this.

MX records have nothing to do with resolving A records. They are for email delivery only.

If you are using internal DNS then that *is* the correct way to fix the problem. The problem that you were having is that when you resolve the public IP address of the server, you can't connect to an internal host using a public IP address. This is usually down to the firewall that you have. Some firewalls won't route traffic back out of the same interface and some will.

Internal DNS is the correct way to get around this.

Chris.
