Controller loses access to Workbench after WindowsXP Service Pack 2 is installed.

Note #: 0134

 

Product: OpenEx

 

Version: All

 

Date Added:  08/26/04

  

Issue:

 

After WindowsXP Service Pack 2 is installed, OpenContoller can no longer access OpenWorkbench. New security settings, included in the service pack, affect the performance of client/server applications.    

  

Workaround:

 

If you have installed, or wish to install, Windows XP Service Pack 2 on a computer using OpenEx, then you must follow the steps below to be able to run OpenController successfully. Note that these steps are to be carried out after installing SP2 and OpenEx.

 

  1. Open the Start menu at the bottom left corner of the Windows XP Desktop

  2. Select Run.

  3. Type dcomcnfg and select OK.

  4. In the dialog box that opens, double-click the following keys in the given order:
    Component Services
    Computers
      My Computer
            DCOM Config

  5. Select XpMaker. Right-click on it and select Properties.

  6. In the Properties box, select the Security tab.

  7. In the Launch and Activation group, select Customize and click Edit.

  8. In the dialog box that opens, you will see two lists – the upper one shows all the users groups that you can configure, the lower one shows the launch and activation rights for the selected group. There will be four entries in the lower list – Local Launch, Remote Launch, Local Activate, and Remote Activate.

  9. Select a group in the upper list.

  10. Deny them the right to Local Launch and Remote Launch.

  11. Allow them the right to Local Activate and Remote Activate.

  12. Repeat 9-11 for each group in the upper list.
