We have an application on Win2K where an apache web server controls instruments via the NI488.2 library (cgi scipt with a c-wrapper around the dll), which is working fine.
After porting the whole application to Win7 and calling the same script from the command line, it is still working fine.
But if the same script is called by the apache server, the connect to the instrument fails, status is 0x8000 .
Here is the NI Spy log:
> 1. ibdev(0, 5, 0 (0x0), T1s (11), 1, 0x0000)
> Prozess-ID: 0x0000056C Thread-ID: 0x00001DD0

For reference, this is the the NI spy log if called via the command line:
. ibdev(0, 5, 0 (0x0), T1s (11), 1, 0x0000)

We are using the GPIB-USB-HS and NI-488.2.2.72
What is giong wrong here?
