IIS 6/SQL Problem with user security

Hi,
I am running WIN2K3, IIS6, PHP 4.3.6 and MYSQL 4.0.18. Here is the problem...we had upgraded from IIS 5 to IIS 6, and everything was working just fine (but before the upgrade we used IIS lockdown which locked out SMTP, because we were not using it at the time. Later we discovered what had happened, and the only way to fix the problem was to re-install IIS 6, which we did. (At that time we also upgraded from php 4.3.4 to 4.3.6) Now, our business directory, which is a php/sql app - seems to have a problem with security. We can log in to the admin part of the app, but cannot make any changes (error message is "Not Authorized") I have a feeling that IIS 6 is not allowing php to write to the sql database, but I do not know where to look for that setting. The rest of the app is working fine - on the public side you can view listings, search the directory etc. without any problems)

Any ideas? (other than suggesting Apache

Find the spot in the code where the "not authorized" message is being created, and find out what event is happening at the time the message is set. Once you discover what action the script is trying to perform when you get that message, it will be easier to troubleshoot.

Thanks for the input - actually I just fixed the problem...re-installed php using the windows installer - and voila! Now it works again.
