Internal and External Domain Name

[Guest]

I've recently run into a problem where users on the LAN side of my network
cannot access their website hosted by and ISP when typing in the
http://www.domain.com address in IE. This occurs shortly after adding my
internal server's DNS IP (192.168.xxx.xxx) in my router's DNS Servers Table
along with my ISP's DNS IP information. I recall reading somewhere that using
the same domain name (domain.com) both internally and externally can cause
problems. Is this the reason I am having this issue? Is there a workaround?

I've read in this forum that adding a record to my zone file may fix this
problem. If so, what type of record (A, Mx, etc.) do I need to create?

Appreciate your help with this one.

You don't need your own MX record, you need to a A records named www, mail,
or whatever name missing from the internal zone to accesss external sites in
the domain.
Just to add, you cannot access the external website by using only the domain
name, the domain name record MUST point to the addresses on all Domain
Controllers which have file sharing enabled. This is for the Domain SYSVOL
share at \\domain.com\SYSVOL

Using the DNS management console, open the domain.com forward lookup zone,
right click in the zone and select new host from the drop down list. Name
this host www, give it the IP of the website, click create. Repeat for other
missing host records such as mail, ftp, and etc.
There is no need for a local MX record for your own domain, even if you had
your own mail server locally, it would need to see its own MX record, it
would already know it is the mail server for your domain.
