fopen causing permission errors on IIS

Recommended Posts


I'm trying to find out how to set the file permissions on an IIS server so I can execute file handling functions such as fopen, fputs, fclose ect.

I know this is pretty basic but I've yet to find a solution.

thanks for your help!

The problem was that I was trying to grant the security permissions through IIS manager instead of simple old explorer.  I just had to grant the default web viewing (in our case: IUSR_WW251)  group permissions to the folder where the scripts were being read.

Here's what I did:

Windows Explorer >> Parent folder where scripts are reading/writing to files >> Sharing and Security >>
Security tab >> Add >> Advanced >> Find Now >> choose default web user (IUSR_WW251) >> OK >> OK
