Installing Client on Non-Domain Joined Server

We have a number of servers that will not be joined to our domain but want to manange with MECM.  There are 3 different locations that these servers can be created in.  I have setup 3 boundry groups for these locations with cooresponding IP's that would be assigned.  I also created 2 additional Distribution Points for each location.

Once the server has been created, I copy the Client installation files over and open up the appropriate ports in the firewall.

My question is, when running the following command:  ccmsetup.exe /mp:<Management Point FQDN> SMSSITECODE=PPP SMSMP=<Management Point FQDN> DNSSUFFIX=<domain suffix>,

If I use the Primary MP and Site Code, it seems to install correctly, but I cannot change Site Code to the site I want it to be on (IE: XX1, XX2, XX3)

I have tried to use the Primary MP for the MP: setting, the SMSSITECODE of the site I want it to be on, SMSMP of the Secondary DP/MP but I get errors on the installation.

Failed to get MDM_ConfigSettings instance, 0x80041013

Count not retrieve value for MDM_ConfigSetting. Error 0x80041013

Failed to read assigned site code from registry. Error code = 0x80070002

Failed to get directory list from http://SecondarySiteServer/CCMTOKENAUTH_SMS_DP_SMSPKG$/TM1000003. Error 0x80070002

At the end, it says Ccmsetup is exiting with return code 0 which says it installed.

Configuration Manager does show in Control Panel, General tab only has Client Certificate, Connection Type and Version.

Any ideas?
