1: Install wordsoftware for office on the server.

2: Enter dcomcnfg.exe in "start"-> "run" to start "Component Service"

3: Double-click "component service"> "computer"> "my computer"> "DCOM configuration"

4. In "DCOM configuration", find "Microsoft Word application", right-click it, and click "properties". The "Microsoft Word application properties" dialog box is displayed.

5. Click the "ID" tab and select "Interactive User"

6. Click the "Security" tab, click "Custom" on "Start and activate Permissions", and then click the corresponding "edit" button. In the displayed "security" dialog box, enter

A "Network Service" user (note that you must select the computer name), and grant it the "local start" and "Local activation" permissions.

7: the "Security" label is still displayed. Click "Custom" on "Access Permissions", and then click "edit". In the displayed "security" dialog box, add a "network"

Service, and then grant the "local access" permission.

In this way, we have configured the DCOM permission for the corresponding word.

Note: This is configured on win2003. On 2000, it may be the configuration of ASPNET users.

Since word is opened on the server, you should write a method to save the exported data on the server and pass it to the client, finally, each time this function is called, all the words previously generated on the server are deleted.
