Version & Build: All
When accessing the Settings panel in WebAdmin or WebMail a “Page cannot be displayed” error occurs. Performing an IIS reset resolves the problem but only temporarily. The Event viewer may show an Application entry: aspnet_wp.exe - Application Error : The instruction at "0x16dbad5f" referenced memory at "0x174eeba8".
The exact cause is not know but seems to be related to IIS or the .NET framework. The administrator will likely see that multiple instances the aspnet_wp.exe process running in Task Manager.
- Stop the IIS Admin Service
- In Task Manager, stop all instances of the aspnet_wp.exe process
- If necessary, use kill.exe to stop these processes
- Start the IIS Admin Service and the WWW Service
