SMSCACHEDIR location

takoroni Have you tried specifying just the MP FQDN (without the https:// prefix) for the /mp command line parameter? According to the documentation, you should only include the https:// prefix when specifying a CMG for the /mp parameter. I wonder if the inclusion of the prefix "breaks" ccmsetup.exe, causing it to revert to the installation properties published in AD.

In the SMSMP client.msi property, the https:// prefix does need to be included. So what you could try for your manual installation is something like this:

ccmsetup.exe /MP:sccmserver.com SMSSITECODE=MCX SMSMP=https://sccmserver.com SMSCACHEDIR="C:\SCCM"

For details, see CCMSetup.exe command-line parameters: /mp and Client.msi properties: SMSMP .

For what it's worth: for domain-joined computers, it's usually not necessary to specify the /mp parameter and/or the SMSMP property, as they will retrieve these values from AD anyway.
