The first method: Hand-registered DLL This method is used from IIS 3.0 to IIS 4.0 and other web server. It requires you to execute in the command line mode, enter the directory containing the DLL, and enter: regsvr32 component_name.dll, for example C: / temp / regsvr32 aspemail.dll, will register DLL's specific information in the registry in the registry in the server . This component can then be used on the server, but this method has a defect. When the component is registered with this method, the component must have the corresponding setting NT anonymous account with permission to execute this DLL. In particular, some components need to read the registry, so the method of this registration component is only used in the case where there is no MTS on the server. Use: regsvr32 / u aspobject.dll Example C: / Temp / Regsvr32 / u Aneiodbc.dll
The second method: Using the MTS (Microsoft Transaction Server) MTS is an added feature of IIS 4, but it provides huge improvements. MTS allows you to specify that only privileged users can access components and greatly improve the security settings on the website server. The steps to register the components on the MTS are as follows: 1) Open the IIS Management Console. 2) Expand Transaction Server, right-click "PKGS Installed" and select "New Package". 3) Click Create An Empty Package. 4) Naming the package. 5) Specify the Administrator account or use "Interactive" (if the server is often used using administrator). 6) Now use Right-click "Components" after the package you just created. Select "New Ten Component". 7) Select "Install New Component" [B]. 8) Locate your .dll file and select Next to complete. To delete this object, just select its icon, then select Delete. Note: Pay special attention to the second method, it is used to debug the best way to write components, without having to restart the machine each time.
