PRB: ASP 0115 a Trappable Error Has Occurred

• Active Server Pages
• Microsoft Internet Information Server version 4.0

SYMPTOMS

When running an Active Server Page (ASP), the following error occurs:

ASP 0115 A trappable error has occurred

CAUSE

An unhandled exception has occurred, and ASP does not have any more information about the error.

Listed below are some of the common causes for ASP returning the 0115 error, followed by some recommended troubleshooting techniques:

• Permission and authentication issues with files and registry keys
  
  Errors may occur if the authenticated user does not have sufficient permissions on other files such as custom components, system dynamic- link libraries (DLLs), and even registry keys.
  
  ASP scripts are typically executed in the security context of the IUSR_<machine_name> account.
  
  If you believe you are dealing with a permissions problem in the registry, you can use Regedt32.exe to examine permissions on the various registry keys. In particular, you may want to look at ODBC, Jet, ADO, and other keys that might be relevant to the problem. If you have a machine that is working properly, try comparing key permissions between the two machines.
  
  The first step is to determine if you really are seeing a permissions problem. A good test is to temporarily add the anonymous logon account (IUSR_<machine_name>) to the administrators group using User Manager. This gives the IUSR_<machine_name> account administrative privileges on the machine. If this causes ASP to function properly, you are almost certainly dealing with a permissions issue.
  
  NOTE: When you have finished debugging, be sure to remove the IUSR_<machine_name> account from the administrators group to minimize the security risk on your server.
