From your other question with the same title, it appears you reran the connector tool to rebuild the IIS connectors. That should have resolved this issue as well. Can you confirm this has been fixed, or are you still having issues? Or did this issue arise after the connectors were rebuilt?
It didn't resolved the issue, please let me know any alternative method to fix the issue.
Can you please create another website and add a new connector with that site. Add a simple cfm page and try it.
Go into your IIS Admin. Open the handler mappings for the site with CF. Double click the .cfm handler. Go to the access tab, what is the access level. Try changing it to execute and see what happens.
