none of the employees were able to see the website internally. Externally it is fine. There are also still a handful of employees that can hit the site without a problem. The majority of use are getting an IIS message that says the site is under construction. There were no changes made that would have caused this. We are running Microsoft Exchange that has Outlook Web Access that uses IIS. Our website is hosted by an outside company. The domain name is a .com but I made an (A) record with www that allowed us to hit the site. Can anyone please help me????

Thanks. We'll let you know when a new response is added.

If your internal root domain name and external domain name are the same then the clients could potentially get confused and try to go to an internal resource when they really should be going to an external resource. You may need to implement SPLIT DNS to get the internal hosts to get to the right website. The working internal clients may have an entry in their hosts file or some other DNS resolution server. Do a Google search for “split DNS” and you will get some good info like this <a href=”http://www.isaserver.org/tutorials/You_Need_to_Create_a_Split_DNS.html”>ISA article</a>. You can also put wireshark on the working hosts and non-working hosts and compare the results when requesting the content of the website of interest.
