Introduction

We need to first make sure that all computers in the workgroup have an Administrator account with the same username and password (no expiry setting on the password) and make sure that the account is not a member of any other group except for Administrators. Login to each computer on the workgroup using this account at least once.

You will have to go through the following steps on both the probe and target computer:

Windows XP and later (including Windows Server)

  1. Select Start then click on Run.
  2. Type DCOMCNFG and click OK. Click No for any warning screens that appear unless it is the User Access Control (UAC) prompt.
  3. Double-click Component Services.
  4. Double-click Computers.
  5. Right-click on My Computer and select Properties.

The My Computer Properties dialog opens

  1. Select the COM Security (Default Security) tab.
  2. In the Access Permissions section, click Edit Default.
  3. Make sure that both "Self" and "System" are listed in the dialog with Local and Remote Access.
    1. Add the Probe's user account, if applicable. To add a user, click "Add..." and type in the missing user names (including domain name) then click OK. You will need to set their permissions to both Local and Remote access.
    2. Click OK to return to the COM Security Tab.
  4. In the Launch Permissions section, click Edit Limits.
  5. Make sure that both "Anonymous Logon" and "Everyone" are listed in the dialog.
    1. Add the Probe's user account, if applicable. To add a user, click "Add..." and type in the missing user names (including domain name) then click OK. You will need to set their permissions to both Local and Remote access.
    2. Click OK to return to the COM Security Tab.
  6. Close the Component Services dialog.
  7. Click OK to exit the My Computer Properties window
  8. Select Start and click on Run
  9. Type WMIMGMT.MSC and press Enter
  10. Right-Click on WMI Control (Local) and select Properties
  11. Under the Security tab, expand the Root folder and select CIMV2. Click on the Security Button.
  12. Ensure that the Probe's and the Administrator's credentials are listed with Full access.
  13. Repeat for the SecurityCenter folder.
  14. Click OK and exit out of the wmimgmt.msc console.

For the edited DCOM settings, it will require we reboot the server after these setting changes. So, whenever you have the chance, reboot the target Device (not the Probe). If this is not possible now, try and just restart the Windows Software Probe services I got you to shutdown and run the following commands on the target machine again.
