Clients that are discovered by the Active Directory System Discovery method are not assigned to the site in Systems Management Server 2003 (888935)

SYMPTOMS

After you run Active Directory System Discovery in Microsoft Systems Management Server (SMS) 2003, you may experience the following symptoms:

Computers that match your SMS site boundaries are not assigned to the site.
After you run Active Directory System Discovery, you can manually install the client by using the Advanced Client Installer (Ccmsetup.exe) on computers that were not assigned to the site.
You find entries that are similar to the following in the SMS\Logs\Ddm.log file on the site server:
CDiscoverDataManager::FilterDDR - Will not create CCR. This item is not assigned to this site. $$<SMS_DISCOVERY_DATA_MANAGER><DateTime>

CAUSE

This issue will occur when all the following conditions are true:

You have not defined the same subnets in the Active Directory Sites and Services snap-in for Microsoft Management Console (MMC) as you have for the Active Directory System Discovery method.
You have not added the Active Directory directory service site name to the SMS 2003 site boundaries.

RESOLUTION

To resolve this issue, you must define the same subnets in the Active Directory Sites and Services snap-in as you have for the properties of the Active Directory System Discovery method. Additionally, you must add the Active Directory site name to the site boundaries of your SMS 2003 site. To do this, follow these steps.

Step 1: Define subnets in the Active Directory Sites and Services snap-in

Click Start, point to Administrative Tools, and then click Active Directory Sites and Services.
Expand Sites, right-click Subnets, point to New, and then click Subnet.
Enter the subnet address in the Address box, enter the subnet mask in the Mask box, select a site name in the Select a site object for this subnet box, and then click OK.
Repeat steps 2 through 3 for each subnet that you have added to your SMS 2003 site boundaries.

Step 2: Add the Active Directory site name to your SMS 2003 site boundaries

Click Start, point to All Programs, point to Systems Management Server, and then click SMS Administrator Console.
Expand Site Database (SiteCode - SiteName), and then expand Site Hierarchy.
Right-click SiteCode-SiteName, and then click Properties.
On the Site Boundaries tab, click the button that has a yellow star to add a new site boundary.
Click Active Directory site, type the name of your Active Directory site in the Site Name box, and then click OK.

MORE INFORMATION

When Active Directory System Discovery finds a potential SMS client computer, it creates a data discovery record (DDR) for that client computer. When a site server receives a DDR, the Data Discovery Manager (DDM) reads the DDR. The DDM determines whether the client that was discovered should be assigned to the site based on the site boundaries that you have enabled for the SMS 2003 site. If a discovered client should be assigned to the site, a client configuration request (CCR) file is created to assign the discovered client to the site. If the discovered client does not match site boundaries, a CCR is not created, and the client is not assigned to the site.
