When you try to connect to the Lacerte Web site or to download updates of the Lacerte Tax program on your computer that is running ISA Server and that is based on either version 2000 or version 2003 of Microsoft Small Business Server (SBS), you receive an error message.This problem occurs when an individual port number is not defined for an inbound and outbound protocol. In this scenario, an individual IP address is also not defined for exceptional proxy settings.

When you try to connect to the Lacerte Web site or to download updates, you receive the following error message:

To resolve this problem, follow these steps:

Under Internet Security and Acceleration Server, expand Server and Arrays, and then expand the computer that is running ISA Server.
Expand Policy Elements, right-click Protocol Definitions, point to New, and then click Definition.
