Extending NAP Infra to High Availability

$
0
0

Hi All,

I have infrastructure as below and its working fine.

I have installed the NAP with IPSec inforcement method in my environment. I have installed Subordinate Standalone CA for NAP on One Server (CA1) and NPS + HRA Role on another Server (NPS1) . I have installed Configuration Manager SHV on the NPS1 Server. Everything is perfectly fine/working from NAP architecture.

Now I have to extend the NAP infra to cater High Availability and Load Balancing. How can I do that one? I would like to know how can I put NPS1 Server Roles into HA/NLB?

Any supported Links? How many more servers do I will require (minimum) and how can I do configuration for the IPSec enforcement method.


Thanks & Regards, Kedar

802.1X EAP-TLS User Certificate Errors

$
0
0

I'm trying to implement 802.1x using EAP-TLS to authenticate our wireless users/clients (Windows 7 computers).  I did a fair amount of research on how to implement this solution and everything seems to work fine when authentication mode is set to: Computer Authentication.  However, when authentication mode is set to "User or Computer" or just "User" it fails.  I get a "certificate is required to connect" pop up and it's unable to connect.

No errors on the NPS side but I enabled logging on the client (netsh ras set tracing * ENABLED) and this is what I can see.  It seems as if there is a problem with the client certificate:

There is clearly something wrong with the user certificate but what? I'm at wits ends as I have tried everything.  Please help!

Need Clarity on NAP Reporting

$
0

Hi All,

I have installed and configured NAP with IPSec enforcement on Windows Server 2012 (NPS1) with separate subordinate CA Server on CA1 Server which is also Windows Server 2012.

With these Two Servers, Everything is working fine as per NAP terminology.

Now I need to Enable or to view the Reports for NAP. I have configured Windows SHV and ConfigMgr SHV on my NPS+HRA Server (NPS1). 

I have followed the following Steps on NPS1 Server:

1. I have downloaded ‘Microsoft® SQL Server® 2012 Express‘ (ENU\x64\SQLEXPRADV_x64_ENU.exe) from http://www.microsoft.com/en-in/download/details.aspx?id=29062 website.

2. I have install DB, SRS & Tools features of ENU\x64\SQLEXPRADV_x64_ENU.exe.

3. I have configured the Accounting for SQL Server Logging using web-siteNAP Reporting http://technet.microsoft.com/en-us/library/dd125332(v=ws.10).aspx

I am able to browse the SQL SRS Website Home page but there are no NAP reports available. I am able to find some data in the table dbo.accounting in SQL Management Studio.

Need Clarity on the below points:

1. What are the different tables/Views are created in SQL Database for NAP so that we can use it for reporting. Any link/article is there to refer?

2. Are there any default reports are available in SRS when we enable SQL Server logging.

3. Do we require seperate SQL Server Reporting Service to host the Reports or SQL Express Reporting Service will suffice the requirement.

4. With reference to the TechNet Article Track Compliance with Security Policies http://technet.microsoft.com/en-us/library/dd125365(v=ws.10).aspx, I need to create these sample Reports. Are these reports are available out-of-box or do we need to create it manually.

5. For these Reports, sample SQL Queries are available (I am not SQL expert to write queries) Please share the link.


Thanks & Regards, Kedar

Hi,

We have created vitual machine which related with server.

But we feel that there is problem between virtual machine and server...Virtual machine loss data or internet connection.

How can we check connection durability between server and VM?

I think ping or tracert commands not usefull in this situation.

Thank's in advance.

NPS IAS/RADIUS problem with Wireless Authentication

I had my 2008 R2 Server working well after configuring it for wireless authentication.  But it has suddenly stopped working.  From the logs, I can see the connection failing with Reason Code 22, which seems to indicate "The client could not be authenticated because the Extensible Authentication Protocol (EAP) Type cannot be processed by the server. "  I can see that there is no "EAP-Friendly-Name" in the failed connection log, but I do not understand why that is.

Any idea why the Server can no longer negotiate an EAP type or the EAP Friendly Name isn't coming through?

The client could not be authenticated because the Extensible Authentication Protocol (EAP) Type cannot be processed by the server.

Computer Certificate Renewal - Failing

$
0
0

Greetings,

System setup:  Server 2008 R2 with "Network Policy and Access Services" role configured to hand out wireless machine certificates to Windows 7 workstations.

This has been set up for a year and has been working well. We have a groups policy which allows for auto-enrollment and all our workstations which are in the correct OU receive a certificate when thye connect to the network.

The machine certs are good for a year.

We are now approaching the end of the first year since we implemented this system and we are starting to see some of our workstations failing to connect to the wireless network.  When we look at the certificates on the workstation we see 2 certificates now (as opposed to the one that was there previously).  One of these is expired and one is current with an expiration date a year from now.  When we manually delete the expired certificate, we are able to connect to the wireless.

Apparently when the certificate is renewed, a new certificate is dropped down, but the old certificate is not removed.  When the machine tries to connect the old cert is found and the connection fails.

What I think should be happening is that the certs should be renewed not replaced, but I can't see anyway to enforce this.

I know that when I manually renew the certificate on the workstation I have 4 choices:

Request Certificate with new key.

Request NEW Certificate with the same key

Renew certificate with new key

Renew this certificate with the same key

What appears to be happening is that the workstations are doing a request, not a renew.

I have been through my Radius config and the GPO and can't find anything that should affect this.  I know that the GPO is being applied to the machines, and I'm about 99% sure that the GPO is correct.

Any ideas where I should be looking?

Thanks,

John Morgan

Can anyone tell me what can I do to avoid this error and connect successfully to my home network?

I have a Meraki wireless network that I have configured to use Radius authentication and it works great.  However, when a domain user tries to authenticate to the wireless network on a non domain computer, I always get Event ID 6274 - Reason There are not sufficient access rights to process the request.  The user is set up in the correct radius group as if they authenticate on a computer on the domain, they do not have problems.  Any thoughts.

Windows VPN access control

I'm looking to have greater control over people logging in using VPN. Currently, I have one NPS policy for employees connecting after hours or those who work remotely.

Now,  I need to allow access to consultants from outside of the company. Preferred method would be IP ACL, which I could do at a switch level.

The question I have is:

Is it possible to have a specific group of users connecting to VPN get a specific range of IP addresses, while all others get default range from DHCP?

VLAN Assignment - Unable to connect to network

$

Hello all,

We have recently setup dynamic vlan assignment on our network, and while it works, there is one thing that is rather annoying/inconvenient about it. After the users try to log in with their AD credentials, a message appears on the screen that says "Connecting to the network", shortly followed by "Unable to connect to the network. Logging on...". The users then log in just fine though - they are placed in the correct vlan, and have the correct network drives mapped. There doesn't appear to be an actual error, so is it possible to get rid of both of those messages? The client PCs are on the domain, they run Windows 7, and they authenticate through our NPS/RADIUS server (running on WS 2008 R2); PEAP-MS-CHAP v2 is the authentication type. Any suggestions/help would be greatly appreciated. Thank you.

Hello,

I'm intending to create ACL in a Layer3 Switch to project our network resources and enhancing the security of our network resources.

Instead of creating plenty of ACLs in the switch, is it possible to use NAP/NAC to protect these resources and allow only certain resources available to our users?

Radius Logging of end user client device IP address not showing up in Logs

$
0

A little back ground,

I am using Server 2012 for Radius authentication of my wireless clients.

This server running NPS (Radius) is not the Domain Controller just a member server on the network.

DHCP is running on another server on my network.

The problem I am having is the Radius logs do not contain the client device ip address only the AD user names.

The logs do contain the Radius server IP address, and the Access point IP address leaving out the client IP address.

This is a School District and we have to filter the internet content for all clients.

Radius is a great authentication method but without the ip address of the clients in the logs I can not apply the proper policies to the different groups. So what happens is everyone get the default most restrictive policy students, and staff.

Bottom line how do I configure the Radius server to insert the IP address in the logs?

Thanks,

Server 2012 NPS NAP DHCP

I've setup a server with DHCP and NPS and configured NAP
DHCP with 1 scope and the default scope options 003 router, 005 DNS server and 015 Domain Name (domain.com)
NPS/NAP DHCP is working (all is setup health, shv, gpo etc..) so when i connect a client with firewall i get a normal IP and when i disable the firewall i get an IP but no gateway and subnet 255.255.255.255 so all works well.

Now in DHCP i created a DHCP policy so i can assign a different DNS server and Domain Name (restricted.domain.com) to non-compliant clients.
Policy i created is as per --> http://social.technet.microsoft.com/Forums/getfile/257005 because User Class option on advanced tab in scope option is not available in 2012)

But when i connect a non-compliant client i still get the DNS Domain Name domain.com instead of restricted.domain.com

ipconfig /all shows its restricted but i dont get the DHCP policy i setup for it
