Problem: Nac with Novell Software - Blue Screen

NAC Appliance and Novell

Hi everyone

Enjoying the title ( problems with novell ), I'd like to post here my problem with workstation that have Novell Software.

So, I have a customer who´s have Nac in his network.

Nac appliance works in Out-of-band Mode - Virtual Ip Gateway.

So the Nac works in almost 99% the totally network. And works very very well.

We have a problems  in some workstation with novell software...(about 6 machines)  Until now I teste 2 workstation with to end-users ( employees ).

So the first workstation since first moment ( windows logon (novel logon), windows initiation, desktop appears,initialization of the software in general, software Cisco Agent appears doing the SSO (authentication, checks Antivirus in AUDIT mode only)... and worked very very well.

The second workstation with other end-user, when the user restart the pc (simulate turnOn the PC), The Nac put the user in authenticated vlan (untrusted vlan), so when appears the windows logon(novell logon) - user put the credencials.

After that , windows start initiating but DON´T appears the Desktop (Blue screen). If the end-user type a Ctrl+Alt+Del and start a new task :  Explorer.exe, appears the Desktop, and we can see all softwares start iniating include the Cisco Agent Software doing SSO and put the user to Access Vlan normally.

So, remeber...  my network works very fine with Cisco Nac. I have 1 machine with novell software works fine without any additional configuration In Nac Manager.

But the rest of this workstation (iqual second machine) have the same problema. (blue screen without initiating the desktop). 

IF I take out  the portprofile in the user interface. The workstation works fine when initiated.

Someone have any ideia about this problem ???????

Ps: sorry about any incorrect word, or expression.

You should write down the error code that appears in the "blue screen". Also , after a "blue screen", windows automatically generates "dump" and/or "minidump" files. You should locate those files and send it to your Microsoft Support, or if you want to troubleshoot it by yourself, you can open the "dump" files with WinDbg software.

When I deployed NAC,  I got bluescreen with the error code 0x40000080 only with a few laptops, and only when they connected or disconnected the UTP cable.

I used WinDbg and found out that the issue was because of a buggy Intel network card driver. Everything worked OK after my customer updated the Intel drivers . In my case the fault was of the Intel driver, we proved that there were no problems with NAC.

Please rate if it helps.
