Install SCCM client on a DMZ / Workgroup machine

I know many people who have struggled with this, but I hope that this quick manula will make this easier.

To install SCCM on DMZ / Workgroup machine first make sure that client can communicate with SCCM server or other roles - that is open port 80/443 to management point, 445 to distribution point and 8530/8531 to software update point. There could be others also depending on the SCCM architecture.

Second, follow this steps on DMZ / Workgroup machine:
1. In the %windir%\system32\drivers\etc\hosts file add following entry:
ip-address management point FQDN

example:
192.168.1.10 sccm.contoso.local

2. In %windir%\system32\drivers\etc directory copy lmhosts.sam file and name it as lmhosts (without extension)
3. In lmhosts file add these entries:
ip-address SCCM Server Netbios name #PRE
ip-address SMS_SLP \0x1A" #PRE
ip-address MP_SMSSiteCode  \0x1A" #PRE

example:
192.168.1.10 SCCM #PRE
192.168.1.10 "SMS_SLP \0x1A" #PRE
192.168.1.10 "MP_001  \0x1A" #PRE

4. The last step is to install client. Copy install files to local directory and run setup with following command:
ccmsetup.exe SMSSITECODE=XXX SMSMP=MP-FQDN

where:
XXX is site code
MP-FQDN is management point FQDN
