Scheduled Crystal Reports failing

I am using BO 4.1 on windows.  We just upgraded our test system from SP5 to SP6 and the scheduled crystal reports began failing after the upgrade.  The failed instance is giving an error that says: "Database Connector Error: 'RFC_INVALID_HANDLE'"

In the server log I can see an error that says:"

assert failure: (.\rasprocUtil.cpp:718). (false : ExtractLogons(): could not extract SI_LOGON_MODE from si_logonsBag property bag). "

This same schedule worked fine in SP 5 but it is failing in SP 6.

Has anyone seen this error before and if so, how do I fix it?

I am going against an SAP BW backend for the data.

Thanks,

Nick
