We  have an application that works on Win 2000 and IIS.

The program written in C and compiled as .EXE, takes data from an HTML form,
uses the cmd shell to copy a template file and replaces the data in the
template with the data from the form. The program then executes another
program which creates data and executes gnuplot which generates plots.

All the above worked fine under Win 2000, but we can't seem to get it to
work under XP Pro SP1 or SP2.

The program runs and has write permissions in the folder because it writes a
debug file with the correct data from the HTML forms. The cmd shells for
copying the file and executing the other program both return -1.

Using IE 6.0 and IIS V5.1. We have turned the firewall off, no virus
software, and lowered security settings for all zones. I even turned off the
Local Machine Lockdown registry values.

Can someone please help with this? I have a deadline comping up in a week.
