Question

HI,
I migrated SCCM 2007 to SCCM 2012 SP1, but the clients does not update the New Site Code Automatically, if I click on Discovery option the client find the new site, but I need do this automatically because are too many clients.
This registry key does not  exist on client computers.
HKLM\Software\Microsoft\SMS\MobileClient\GPRequestedSiteAssignmentCode
HKLM\Software\Microsoft\SMS\MobileClient\GPSiteAssignmentRetryInterval(Min)
HKLM\Software\Microsoft\SMS\MobileClient\GPSiteAssignmentRetryDuration(Hour)
Any Help?
Thanks.

Hello ICH-CR,
Thanks for writing to the SysCtr ConfigMgr forums.
I think there are multiple solutions to this issue and you can choose whatever fits best to your scenario.
1. While upgrading the clients from SCCM 2007 to  2012 you can assign the clients to your ConfigMgr 2012 site.

You just need to ensure that you have a boundary group and boundaries. More details on

I would suggest the first method because if you create  another child site, you shouldn't have to reassign the clients back again. If that is unlikely then use the following script which is method no 2
2.

This is a VBSCRIPT and  can be ran from a network location using the PSEXC
3. Here is a smaller script
'Replace with your Site Code sSiteCode = "EnterNewSiteCode"
sMachine
= "."
set oCCMNamespace
= GetObject("winmgmts://"
& sMachine & "/root/ccm")
Set oInstance
= oCCMNamespace.Get("SMS_Client")
set oParams
= oInstance.Methods_("SetAssignedSite").inParameters.SpawnInstance_()
oParams.sSiteCode
= sSiteCode
oCCMNamespace.ExecMethod
"SMS_Client",
"SetAssignedSite",
oParams
You can use this script as a logon script .
