I'm building a SCCM12 Lab to toy with. Infrastructure is:
- 1 CAS
- 1 Primary
- 1 DC
Both the CAS and Primary servers are WSUS/SUP enabled, with the CAS synchronizing with Microsoft while the Primary is synchronizing with the CAS (upstream synch). Databases are SQL Server 2008 R2 Standard.
WSUS settings are deployed through GPO, assigned to all 3 computers, specifying the Primary server as source.
