I am using Exchange 2003 and Windows Server 2003 to implement a workflow application. I have done all the things listed below and still can not get the debugger to launch by placing a 'stop' statement in the script: If you are using the Workflow Designer for Exchange 2000 Server, enable Just-In-Time (JIT) script debugging. For JIT to work correctly, the server environment must be set up properly. The following three requirements must be met: The workflow event sink COM identity must be set to "interactive user" in component services. The registry key "HKCU/Software/Microsoft/Windows Script/Settings/JITDebug" must be set to REG_DWORD "1". If the event sink is installed on the server, JIT must be enabled in Tools|Options|Debugger|General in Microsoft® Visual InterDev®. Thanks, Gary Marshall
