Over a year ago, I deployed an ASP.Net C# v 1.1 framework application with several Crystal Reports to a client server running Crystal Reports Server XI. All of the reports worked without any problem and have been working and being used continuously for several months.
About two months ago, some of the reports stopped running on the client machine for unknown reasons. The rest of the application runs without any problem.
The reports that still run properly make a direct connection to a Sql Server database to populate their records
The reports that no longer run are populated from an ADO .Net typed dataset.
While I do not know if there is a relationship, the client virtualized the web server on which this web application resides with VMWare at around the same time these reports stopped working.
Does anyone have any thoughts as to what might be causing this issue, how it might be resolved, or what steps I might take to troubleshoot it and identify the problem that is occurring?
