I can't get an ADO SQLv2 sensor to work with an Informix DB through ODBC on a Windows Server 2012. Tests through Windows odbcad32 work without any errors. The sensor ist setup with default settings and the connection string is a simple "Provider=MSDASQL;Dsn=_name_of_system_dsn;" This triggers the following driver error:
ERROR [HY000] [Informix][Informix ODBC Driver][Informix]Internal communications buffer management error detected
According to the IBM knowledgebase, this usually indicates faulty RAM. However, since the ODBC test on its own works, I suspect something's going wrong between prtg - msdasql provider - odbc?
