Why Does SEP LiveUpdate Fail on a Non-Compliant NAP-DHCP Client?

Hi,

I'm currently testing NAP-DHCP in our environment. NAP components have been installed on a Win 2008 R2 enforcement server and NPS policies defined too. However, once I enable NAP on a DHCP scope, I can ping, view and use shares on the SEP remediation server, from our Win 7 clients. But, when I try running liveupdate on this same machine, it fails to contact to the server. And when I check the SEP client's connection status, it says 'Connected'.

What am I missing? Pls advise.

You can see the napagent status on the machine and check what is being enforced through this command.
netsh nap client show state
and also
napagent

NAP prevent communication between compliance clients with non-compliant clients, NAP don´t disconnect clients that's why you see the status connected.

What NAP does is to verify if the client is compliant with SHVs (System Health Validators) defined by your organization, when all the requirements are in place this clients can access to the Secure Network, Boundary Network and restricted Network.

When a client is non-compliant he just have access to a limited Network in this case a Restricted Network until he become compliant, he can check the remediation servers because NAP remediation servers can provide updates and services to noncompliant client computers. Depending on the design of your remediation network, and a remediation server can also be accessible by compliant computers.

I hope it helps.

@David,

Thanks for your feedback. The NAP setup has all components running, but the SEP liveupdate still fails to run successfully. I'm wondering if there's an additional component that needs to be installed for SEP definition-updates to run.

Hi U-g-o,

probably it´s because SEP is not integrated with NAP. SEP has its own NAP Enforcement called SNAC.

You could check this Question posted here in EE they explain very well the concepts.

Let us know if helped.
