ASP. NET is not authorized to access the requested resources. Consider granting the ASP. NET Request identity the permission to access this resource. ASP. NET has an applicationProgramNo base process ID used for simulation (usually {MACHINE} \ ASPnet on IIS 5 and Network Service on IIS 6 ). If the application is simulating through <identity impersonate = "true"/>, the identity will be an anonymous user (usually IUSR_machinename) or an authenticated user.

To grant ASP. NET write access to a file, right-click the file in resource manager, select "properties", and select the "Security" tab. Click Add to add an appropriate user or group. Highlight the ASP. NET account and select the corresponding access permission box.

 

after searching for a long time on the Internet, I was prompted to use the dcomcnfg tool to modify the access permission. So I tried it. The operation was successful as follows:
1. Enter dcomcnfg in the command line, the "component service" Manager is displayed.
2. Choose "component service" computer ">" my computer ">" DCOM configuration ", find" Microsoft Word Document ", right-click, select "properties"
3. Click the "Security" tab in the "properties" dialog box, and select "Custom" in "Start and activate Permissions ", click "edit" on the right, add the "ASPnet" (netword service in IIS6) user to the dialog box that appears, and give " Local start " and " Local activation " permissions, click "OK ", disable the component service manager.
in this way, you can access the word object on the Asp.net page.
