SCCM discovery problems

I have installed SCCM 2007 R2 on a domain member server. The SQL 2005 Server which hosts the database resides on a different domain member server. It appears that I have a stable configuration, in that I have no errors in the "System Status" area of the Configuration Manager Console, and the SCCM server has the proper permissions on the SQL database. However, after completing the Discovery process, I can only see the SCCM server itself and the SQL Server, none of the other servers or workstations is present. I have used both the "Active Directory System Group Discovery" method and the "Network Discrovery" method. As far as I can tell, I have the permissions set correctly both within the AD, as well as the SQL Server. I extended the AD schema prior to installation, but I notice that there is no value in the "Site Code" area, except for in the "All Unknown Computers" collection, which has two computers listed. Do I need to extend the AD schema again, or is there something else I missed?

In order to get computers discoverd from your AD you have to configure the Active Directory System Discovery and define your domain there
If this does not work
Also check the logfiles on the SCCM program directory especially Ddm.log
did you just install it , Allow few hours for it to run , you have to be patient with SCCM ? you mentioned that system status is showing ok for all compnent , just give it few hours and test . if it `s been long time since you did configure discover , then try run as soon as possbile option on the discovery and test again . if after all tests and nothing shows up then make sure the clients don`t have firewall on if so you have to disable it or add firewall exception .

Good luck

@Merowinger: I had originally configured "Active Directory System Discovery" to point at the top level of my AD domain. When I instead specified the OUs that contained the workstations themselves, I was successful. It just seems a little odd, because I also configured "Active Directory User Discovery" to point to the top level of the AD domain, and all of my users, who reside in disparate OUs, appeared. Is this right?
i just don't know if there are dependencies between the AD discovery methods. In generally i enable all of them and link them to the top of the domain
