PERL Scripts Fail to Execute & Not Load the Advapi32.dll File

 Last reviewed: April 18, 1997
Article ID: Q155357

The information in this article applies to:
  • Microsoft Internet Information Server version 1.0

SYMPTOMS

When you run a PERL script with Microsoft Internet Information Server (IIS), you may get the following error: 

   CGI Error:
      The specified CGI application misbehaved by not returning a
      complete set of HTTP headers. The headers it did return are:

      Cannot load advapi32.dll.
However, the PERL script will run without errors from the command line without using IIS.

CAUSE

The Advapi32.dll file is used by PERL and in turn, tries to open another DLL in the Microsoft Windows NT System32 directory. If it fails to load the DLL in \System32, Advapi32.dll will also fail to load causing the above error message.

WORKAROUND

The credentials of the IUSR_servername (IIS anonymous account) are used to access the Windows NT System directories. If this account does not have sufficient privileges to a file or directory, PERL or other CGI scripts may fail to execute.

Check the permissions on the Winnt\System32 directory and make sure the IUSR_servername account has sufficient access.
