Problem Analysis:
Prompt Server.CreateObject failure, must be a component problem, should start from the component

Resolution process:
Restart IIS, unsuccessful;
Reinstall AspJpeg, unsuccessful;
In the ASPJPEG.DLL directory execution Regsvr32 Aspjpeg.dll, prompt registration success, the operation still fails;
Switch AspJpeg Another version of the installation, running failed;
An attempt was registered to register this component in the component service and failed to run;
Consider whether it is other issues, think of the component permissions, to Aspjpeg.dll plus everyone Full Control, restart IIS, run continue to fail;
Change the anonymous user iusr_**** for IIS to a user in the Administrators group, enter the user password, reboot IIS, and execute successfully.


The problem is half solved, aspjpeg already available, but this solution does not solve the problem completely, but also creates security problems. Local tests can use this method and cannot be used in places where security needs are high, such as servers, and continue to find solutions
Disadvantage of this method: After the anonymous user who gave IIS is the Administrator group, the Access user of IIS is logged in as the administrator, in the server environment, the client user can easily control the server or even destroy the server.
New solutions:
Click "Start"-"Run", enter "Regedt32", click OK to run the Registry Editor;
Click on "HKEY_CLASSES_ROOT", "Persits.jpeg", click on the Editor window toolbar "Security"-"permission", add "iusr_xxxx" user, select "Read" permission, click OK;
Click on "HKEY_CLASSES_ROOT", "Persits.jpeg.1", click on the Editor window toolbar "Security"-"permission", add "iusr_xxxx" user, select "Read" permission, click OK;
Click the Close button to launch Registry Editor;
Reboot IIS;
Access to ASP probes at this time, the AspJpeg item has been shown to support the problem successfully resolved.
