Problem with Perl / PHP

[popminister]

Hello,

I've written a perl script that makes it possible to check username/password combinations against a NT4 Domain.
Now I need to do the following:

• My PHP Script has got a Username/Password Form.
• The Script should send the values to the Perl Script.
• The Perl Script checks if the user is member of the domain.
• and then it returns s.th. like "loggedin"
  or "false"

After reading the Documentation I found out, that the best way to do this must be use one of the functions "system, exec or passthru".
While trying each of them I got several errors and everytime I started my Script a DosBox popped up.

I am using PHP4 on WinNT4 Server with IIS 4.0 and Activestate Perl.

Thank you in advance.
