Unable to access company's website from Internal computers

Hello,

None of the users at my company are able to access company website which is hosted outside of servers. I am able to access the company website from computers outside of our networks.

I have researched the issue and read many posts but could not find the solution. Below is the setup of our DNS settings.

After I opened DNS console it listed the following:

Forward Lookup Zones
>_msdcs.example.local
>example.local
>companywebsite.com

example.local shows names of computers/sever on our network and their IPs.

Within companywebsite.com under Forward Lookup Zone I have the following entries
Name: www Type: Host (A) Data: IP address for company website
Name: www Type: Pointer (PTR) Data: companywebsite.com
Others entries listed are:
SMTP that shows ip address for exchange sever/domain controller (I have one server that acts as exchange and domain controller).
(same as parent folder) - few entries that range from Start of Authority to Name Server (NS) to Mail Exchange.


Are the settings correct? do I need to make any changes?

Thanks,
B
