Creating Active Directory user from ASP page

I am able to create a user in AD with the following script from an ASP page, with Anonymous user disabled in IIS, logged on to the server as an administrator.

============================================
Set objOU = GetObject("LDAP://OU=testing,DC=test,DC=com")

Set objUser = objOU.Create("user", "cn=" & sUsername )
objuser.put "samAccountName", sLogon
============================================

My question is:
How to run the asp page that has the code above located in a different machine?

When I post the page located in a different machine, I get "HTTP 500.100 - Internal Server Error - ASP error
Internet Information Services" error.

When I run it from my machine It works fine.

What might be the problem?

Thanks for any help.
