One of my co-workers successfully connected to the Crystal Server and saved a report using Save-As-Enterprise from Crystal Rpts 2011 [Developer] on a PC that does NOT have Harvest software change manager [CA SCM Workbench Release 12.0.2] installed on it.
Our current assumption is either a DLL or some sort of Port issue. The CA SCM application has some built-in Crystal Reports (BusinessObjects Enterprise) functionality (not used by us) but possibly impacting our Crystal Enterprise connectivity.
That's all of the information that I have at this time, but will provide an update if/when I found out anything more.
