Hi!
IMO it's not connection settings, but error in your program. In asynchronous mode you should check value returned from SQLMORERESULTS() and call in repeatedly until it returns non-zero value before calling other SQL pass-through function. Or call SQLCANCEL() before calling other function to break execution. Timing issues can explain different execution on laptop and desktop.

>I am developing a VFP application using a SQL Server 7 backend. I am working on a desktop with SQL Server installed on the desktop. I installed SQL Server on a laptop and moved the application to the laptop. On the laptop only, I keep getting the message "Invalid call issued while executing a SQLMOREREULTS() sequence." I have played with the ODBC connection "Batchmode" and "Asynchronous" settings to no avail.
