Yep! Associations blow the shebang line on Win32. You can change the association to include -T, but that is now global. Better, use runperl.bat ( this one i advocate ) or pl2bat.bat to wrap the code, executing the perl interpreter w/ -T on a per-script basis ... I haven't played w/ .bat and IIS ( why are you running IIS after nimda, anyway? ) but it should work.
