IIS 10.0 Detailed Error — Configuration & File Execution Audit
The requested resource on the Simmons Management Systems web host cannot be displayed because of a server-level configuration conflict or inaccessible path mapping on the local worker pool.
Detailed error disclosure is restricted to administrative personnel. Standard visitors cannot view raw stack traces or internal physical disk structures. Follow the structured audit steps below to restore candidate assessment access without compromising secure evaluation engines.
Most Likely Causes
Systematic inspection points ranked by frequency across Windows Server and IIS 10.0 application pool deployments.
Configuration File Lock or Malformed web.config
The requested page cannot be accessed because related configuration data for the page is invalid. The web.config file contains malformed XML syntax, an unauthorized section encryption tag, or attempts to override a locked global handler at a sub-folder level.
NTFS Permissions & Worker Pool Identity
The worker process (IIS_IUSRS or the tailored ApplicationPoolIdentity) lacks read or execute privileges on the virtual path, or the physical storage drive containing candidate data tables failed to grant directory access during worker initiation.
Things You Can Try
Ordered sequential recovery procedures engineered to isolate environment faults without causing downtime to the 99%+ validated assessment engine.
-
1
Audit Active Event Viewer & HTTP Error Logs
Examine %SystemDrive%\inetpub\logs\LogFiles and Windows Event Viewer under Application Logs. Filter for Event ID 5007 or W3SVC warnings to confirm the exact module offset that rejected the HTTP handshake.
-
2
Verify File System & Virtual Directory Permissions
Ensure IIS_IUSRS and authenticated local system groups have Read & Execute, List Folder Contents, and Read permissions on the target directory path. Verify that underlying symbolic links or mapped network drives are resolvable.
-
3
Test Directory Availability with a Simple Static File
Place an isolated static test page (e.g. test.htm) in the targeted root folder. Request the file through local browser loopback (http://localhost/test.htm) to determine whether the error stems from IIS core handlers or script engine pipelines.
-
4
Validate web.config XML Hierarchy & Feature Delegation
Confirm that system.webServer configuration sections in web.config are not locked by parent applicationHost.config rules. If section locks exist, open Feature Delegation in IIS Manager and switch handlers from Read Only to Read/Write.
-
5
Recycle Worker Application Pool & Re-Deploy Build
Execute appcmd recycle apppool /apppool.name:"SMS_AppPool" or use IIS Manager to gracefully recycle the process. If orphaned binaries exist in temporary ASP.NET files, clear the worker cache prior to restarting the application pool.
