To configure the infrastructure to support the Microsoft Compatibility Exchange Configure your firewalls and URL scanners to allow access to the Microsoft Compatibility Exchange, as follows:
1. Allow outbound access for the standard Secure Sockets Layer (SSL) TCP port 443, on any computer running the Application Compatibility Manager.
2. Restrict outbound access to the Microsoft Compatibility Exchange, allowing access only from designated computers and designated users within your organizations.
3. Enable access to the Microsoft Compatibility Exchange URL, https://appinfo.microsoft.com/AppProfile50/ActWebService.asmx, (only necessary if passing through a firewall).
