Marco,

Make sure that you install The most recent VFP service packs to all machines compiling the DLLs and to all the web servers running the dlls. This should solve your problem.

You should also as a matter of fact make sure your servers have the latest OS and IIS service packs installed.

>We have a VFP dll running in a ASP-application on IIS.
>In the config.fpw we have TMPFILES=G:\temp

>Every hit i log the setting with SYS(2023).
>After some hits VFP has lost its setting. SYS(2023) returns C:\WINNT\TEMP

>Also SYS(2023) sometimes returns a strange invalid path that looks like a string from the SET('PATH') setting.

>The environment has no servicepack of VFP installed and is a dualprocessor system.
