noteNote
The following topic pertains to Windows Server® 2008 R2, and Windows Server® 2008 only. For information about installing NPS in Windows Server® 2012, see Install a NAP Health Policy Server

There are multiple ways to install NPS, and to understand the differences between these methods, an understanding of the Network Policy and Access Services (NPAS) server role is required.

The NPAS server role is a logical grouping of the following network access technologies:

  • Network Policy Server (NPS)

  • Routing and Remote Access service (RRAS)

  • Health Registration Authority (HRA)

  • Host Credential Authorization Protocol (HCAP)

These technologies are the role services of the NPAS server role. When you install the NPAS server role, you can install one or more role service while running the Add Roles Wizard.

noteNote
The Add Roles Wizard is opened by using either Server Manager or Initial Configuration Tasks.

After you have run the Add Roles Wizard and you have installed one or more role service of the NPAS server role, you cannot install additional role services by using the same wizard.

For this reason, if you run the Add Roles Wizard and you install NPAS role services other than NPS, you cannot run the Add Roles Wizard again to install NPS later — you must instead open a similar wizard named the Add Role Services Wizard.

If you want to install NPS, and you have not yet installed any other role services of the NPAS server role, follow the instructions in the procedure Install Network Policy Server (NPS).

If you want to install NPS, but you have already installed other NPAS role services, follow the instructions in the procedure Install NPS by Using the Add Role Services Wizard.
