When building a K2 process in K2 blackpearl 0807 the SharePoint Events Process wizard will not accept a valid SharePoint URL and the user is prompted to specify the SharePoint site URL even though it was already correctly filled in with the value stored in the Environment Library for the SharePoint service. The result is an error and the wizard configuration cannot be completed. The error is caused by the IPv6 TCP protocol being set to enabled. "Windows Vista" or "Windows Server 2008" as a client or server uses the "new" IPv6 TCP protocol as its default networking protocol forcing the validation calls testing for MOSS server status and port availability to supply IPv6 protocols as the communication layer.

The local machine has the following items installed:

  • K2 blackpearl 0807 4.8210.1.x or 4.8210.2.0
