A remediation server group is a list of servers on the restricted network that provide resources required to bring noncompliant Network Access Protection (NAP)-capable clients into compliance with administrator-defined client health policy.

A remediation server hosts the updates that NAP agent can use to bring noncompliant client computers into compliance with health policy, as defined in Network Policy Server (NPS). For example, a remediation server can host antivirus signatures. If health policy requires that client computers have the latest antivirus definitions installed, an antivirus system health agent (SHA), an antivirus system health validator (SHV), an antivirus policy server, and the remediation server used to host the antivirus signatures work together to update noncompliant computers.
