Change Site Code of Configuration Manager Client

In this short post we will see how to change site code of Configuration Manager client. Every site has a site server, a site database, and a three-character alphanumeric site code. The site code must be unique in the hierarchy.

Site codes are used to identify the sites in a Configuration Manager and site code must uniquely identify each Configuration Manager site in the hierarchy. Having said that there might be reasons why you want to change the site code of the configuration manager client.

Let’s assume you have ConfigMgr 2007 installed in your company and now you want to migrate the objects to Configuration manager 2012. ConfigMgr 2007 and SCCM 2012 publish information into the same Active Directory system folder when implemented in the same domain. As a part of the migration process, you should plan for new site codes for your System Center 2012 Configuration Manager hierarchy.

Configuration Manager Client Site Code

When you are choosing the site code while installing SCCM you should keep few things in mind.

1) Avoid using reserved names such as AUX, CON, NUL, PRN when choosing site codes. Click this link to see list of reserved file names.

2) Avoid reusing site codes previously used in your ConfigMgr hierarchy. Configuration Manager Setup does not verify that the site code entered is not already in use. Site codes are stored in the site databases.

Change Site Code of Configuration Manager Client

Now we will see how to change site code of SCCM client using a script. In the below script replace your site code in place of P01 and save it as filename.vbs. The script can be downloaded here.

On Error Resume Next
set oSMSClient = CreateObject ("Microsoft.SMS.Client")
'if Err.Number <>0 then
'wscript.echo "Could not create SMS Client Object - quitting"
'end if
'Assign client to Servername
oSMSClient.SetAssignedSite "P01",0
set oSMSClient=nothing

If you want to change the site code on a single computer then copy the script to the computer and run the script. If you are looking to change the site code for set of computers then let’s see how to do that.

Launch the configuration manager console, navigate to Software Library > Packages. Right Packages and click Create Package.

Hi Prajwal,

This script does nothing to me, below is the message I get in execmgr.log file

CServiceWindowsEventHandler::Execute – Received SERVICEWINDOWEVENT : END EVENT
Service startup.

That’s it. Appreciate your help here.

Hi

after changing the sitecode, i am unable to launch software center. i am running sccm 2016 1710

Alex

you actually need to change SMSSLP in the registry too. Under HKLM\Software\Microsoft\CCM

Must be 2012.. his screenshots are of 2012, and his scenario was migrating from 2007 to 2012. What i don’t get is how do you already have a Windows 7 collection in the new site? Those machines must have been discovered first right? And if so, wouldn’t they already have the client installed, pointing them to the new site code?
