This is an IIS issue. Your installation of Perl is OK. You have to remember that IIS is running as a different account. If your script doesn't have permissions to accomplish the task, usually your script will just not run that part. When you make system calls w/in your Perl scripts that are run via IIS, you have to remember to set your environment just as if you were running it from the same cmd.exe environment. The easiest way (not the safest) is to use IIS admin tool to set your script up to run as you and then restart the server. If it runs as expected, that means you have to think about the security issues of running it that way, but it gets it working in the short term. This was a problem for Net::Ping users that developed IIS apps to use it... their scripts had to be run as Admin... yuch. Win32::PingICMP uses a dll which is the same that Win uses to allow anonymous ping. Hope that helps :) (been there too) JamesNC :0)
