    Default Computers on internal network cannot access websit

    any ideas? Outside computers can get to the websites, but internal cannot. IIS server is NAT'd.

    Default Do a ping from..

    .. the inside and find out the IP address that is returned.<BR><BR>Chances are, it is returning the outside IP address (which your internal computers have no clue about).<BR><BR>From what I saw in the past, our network guys used HOSTS files and then ultimately ended up setting up an internal DNS server for the LAN.

    Default Yeah, we have the same...

    ...setup/problem. I have a program which checks web links. Works fine on external sites, but the firewall returns the external addresses for sites hosted on our servers, which the servers themselves cannot see.<BR><BR>Basically we have an internal DNS server which the network which the servers sit on have access to which contains just the internal domains and their internal addresses.<BR><BR>Works quite well. Not sure how hard it is to set up, wasn&#039;t involved.<BR><BR>However, if you have only a small number of computers/sites which don&#039;t change very often, you can modify the file called "hosts" as Doug said - basically it&#039;s a DNS cache which windows will use instead of a remote DNS server...<BR><BR>Craig.
