Internal DNS to External Website
I was just made responsible for our small network (12 users) when our manager left to take a better job. When my users try to go to our external website they get a page cannot be displayed error, but if they are not in the office they can access it without issue. I called the old manager and he was not very helpful. However, I do remember at some time he was trying to setup an intranet site for the company. I think he setup DNS somewhere that routes all traffic going to our external website to that internal instranet website. Needless to say he did not complete that task (was a common issue) and I now need to at least undo the DNS setting so all the users can get to the external facing website for our company from their internal PC's. I am not well versed in DNS, but do have good basic networking skills. Can someone point me in the right direction as to how to correct this?
TIA

On one of the PC's in question please go to Run and type cmd, then from there type ipconfig /all, please list your results here. Also can you give me an idea of the network setup? Like Router IP, Server IP and so on
Are you running this server internally?
What is the internal IP address of the server hosting your website?
What is the internal IP address of the server hosting your website?
Type
ping websiteaddress.com
from the client machines
it may resolve an internl network address.
now go the DNS Server Console.
dril down to the forward lookup zones and find the record assigned to that ip address.
delete it.

I tried what you kind folks have stated and it has not worked. Here are the details. When I do a ipconfig /all on a client I get this:
C:\>ipconfig /all
Windows IP Configuration
Host Name . . . . . . . . . . . . : sacabc_8
Primary Dns Suffix . . . . . . . : southatlantic.org
Node Type . . . . . . . . . . . . : Hybrid
IP Routing Enabled. . . . . . . . : No
WINS Proxy Enabled. . . . . . . . : No
DNS Suffix Search List. . . . . . : southatlantic.org
Ethernet adapter Local Area Connection:
Connection-specific DNS Suffix . :
Description . . . . . . . . . . . : Intel(R) PRO/1000 MT Network Connection
Physical Address. . . . . . . . . : 00-08-A4-A4-F6-74
Dhcp Enabled. . . . . . . . . . . : Yes
IP Address. . . . . . . . . . . . : 192.168.10.144
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.10.252
DNS Servers . . . . . . . . . . . : 192.168.10.1
In the DNS server there are two entries to the 192.158.2.1 address. They are:
-DNS->SACSVR01->Forward Lookup Zones->southatlantic.org
(same as parent folder) 192.168.10.1
SACSVR01 192.168.10.1
More info:
All DNS traffic appears to be pointing to the SACSVR01 server (192.168.10.1) and all web access works except to our external site. It's strange. Why would I need an A record to go to an externally hosted website. The name resolution should be the same as any other externally hosted website right?

192.158.2.1 should be 192.168.10.1. Fat fingered that one. :-)
What is the result for
ping external-site-address.com( this is your externally hosted website)
on client computers
