I am having probs with Fopen as well. Recieving this error when attempting to write to textfile PHP Warning: fopen(TS345.txt) [function.fopen]: failed to open stream: Permission denied in c:\Inetpub\wwwroot\index.php on line 135 PHP Warning: fputs(): supplied argument is not a valid stream resource in c:\Inetpub\wwwroot\index.php on line 235 PHP Warning: fclose(): supplied argument is not a valid stream resource in c:\Inetpub\wwwroot\index.php on line 137 PHP Warning: mail() [function.mail]: SMTP server response: 550 5.7.1 Unable to relay for the_only_uglytroll@shaw.ca in c:\Inetpub\wwwroot\index.php on line 170

HAving a hell of a time getting PHP to function on MS IIS. It says everything is there as far as extensions etc go, but when I try to test (Write inputfield variable to textfile) nothing happens. It's a very basic php script 7 lines long, but doesn't function. Several other people have used it succesfully on PHP enabled servers. I think I may have bunged the install, but have tried re-doing the install like 13 times. ARRRGGHHH. Can someone please help me set up PHP so it works?
