Install and Configure PXE Service point

PXE Service Point:

Definition:
PXE service point is a site system role in SCCM 2007 that is used to deploy Operating Systems. This role  initiates the OSD process and responds to network PXE boot requests.

Ports used :

Client to PXE service point: 
  • DHCP- 67 and 68
  • TFTP-69
  • Boot Information Negotiation Layer-4011
Site Server to PXE Service Point:
  • SMB- 445
  • RPC Endpoint Mapper-135
  • RPC-Dynamic port allocation

Creating PXE service point:

1. In the Configuration Manager console, navigate to System Center Configuration Manager / Site Database / Site Management / <site code> - <site name> / Site Settings / Site Systems, select the SCCM server where the PXE Service point has to be installed and click on new roles as shown,

Enter the FQDN of the SCCM server and click next.




2.  On the System Role selection page, select PXE Service Point.Click  Next.
When you click Next, a pop up will appear saying that "enabling this site system role will open the above mentioned ports". Click yes.


3. On PXE-General tab, do the following:

  • Check the option "Allow this PXE point to respond to incoming requests", this will allow the computers  to use this.
  • Check  " Enable  unknown Computer support" to enable  the support for computers when the computer information is not imported or discovered in SCCM.
  • Check the require password option if any password is required to start the process. Note that for unattended installation, this option should be unchecked.
  • Select the Respond to all network interfaces default option.


4. On the PXE-Database tab, specify the account to be used and the certificate creation details. Here, I am going with the default selections.
