ISSUE:
Logging on to the CMS causes the error message, "Error 4146: Connection could not be established with the remote host."

RESOLUTION:
This error may be caused by the configuration of your firewall. The CMS attempts to make direct contact with our servers via port 80. If you have prohibited access to port 80 without going through your proxy, the CMS will not be able to function.

There are two possible ways to solve this problem.

1. By simply changing the configuration of the firewall to allow the CMS to make contact with our servers via port 80, the CMS will run correctly. Contact Technical Support for any addresses needed to set this up.
2. You can configure the CMS to connect to our servers through your proxy. In the CMS folder on your local computer, there is a file named "lmimcmsini.xml." Open this file in a text editor. You will see the following text.
   
        <proxy ip="-1" port="-1" />
   
   Change the value of ip from "-1" to the address of your proxy, and change the port from "-1" to the correct port. For example:
   
        <proxy ip="10.0.0.14" port="8080" />
   
   After making this change, the CMS will connect to our servers through the proxy.

NOTE: You will not be able to use LarsonMath.com: Intermediate's CMS if your proxy server requires authentication.
