Patch Manager Computer count under Managed Computers are different from those in WSUS or even the Update Services node view

Patch Manager consumes one node for every computer it manages. Managed computers include all WSUS, SCCM, and Patch Manager servers, along with all managed clients. The Primary Application Server (PAS) calculates the number of managed computers using two sources:

• The Enterprise > Managed Computers node
• The Administration and Reporting > Task History node

• Managed computer inventory is not run against some computers

Run a Managed Computer Inventory task against the computers in the Update Services node to resolve this.

To run a Managed Computer Inventory task against the computers in the Update Services node:

1. 1. In the Patch Manager console, expand Enterprise > Update Services, and then expand your update server.
   2. Expand Computers and Groups, and then select All Computers.
   3. In the Actions pane (right), click Inventory.
   4. On the Inventory Options window, select Inventory - include specific datasources, and then select the appropriate datasource option.
   5. Click OK.
   6. On the Task Options Wizard - Inventory Task window, click Select computers using rules.

The Computer Selection Rule Management window opens with All computers in the selected WSUS Computer Group already selected.

1. In the field at the top of the window, enter a name for your new ruleset.
2. In the Computer Filter section, select and configure the Only include computers that have a reported time option to avoid exceeding your Patch Manager license.
3. Select or clear any other options as necessary.
4. Click OK.
5. Click Yes to save your changes.
6. Click Yes again to confirm your selection, and then click OK on the success dialog.
7. Back on the Task Options Wizard window, click Next.
8. Specify your scheduling and notification preferences.
9. Click Next.
10. Click Finish.
