Pharos has identified an incompatibility between Blueprint Enterprise 5.0 and the installation of Microsoft KB 4056897 for Microsoft Windows 2008/2008R2 Server.
Specifically, if this Microsoft patch is applied in a Blueprint 5.0 environment (including Service Packs 2 and 3) the Tracker Web Service will fault. This will affect a server’s ability to respond to installed Blueprint Tracker client requests and uploads.
If this Microsoft patch is a requirement in your environment, install Service Pack 4.1 for Blueprint 5.0 before installing the Microsoft patch. Or, you can upgrade to Blueprint 5.1 or the latest release, Blueprint Enterprise 5.2 R2. If you have already installed this patch and experienced this problem, you will first need to uninstall the Microsoft patch prior to updating your Blueprint software.
