I've seen a handful of Vista Business machines with this issue. The issue has occurred on both 32bit & 64bit machines. I haven't determined why this specific file isn't being updated by the associated patches on certain machines.
Here's a Brute force fix: Find a known good copy of the bthport.sys (The file is different for 32bit & 64bit OS). Here are the correct versions for Vista SP2: (According to: http://support.microsoft.com/kb/2532531 ) Bthport.sys 6.0.6002.18457 508,416 21-Apr-2011 13:55 x86 Bthport.sys 6.0.6002.18457 695,296 21-Apr-2011 14:17 x64 Create a temporary folder for the file. (Let's make it C:\Temp) Copy the C:\Windows\System32\drivers\bthport.sys taken from the good machine to C:\Temp folder on the problem machine. Open an Administrative Command prompt. (Click on the Windows Start button, type CMD, cmd.exe should show up in the search results, right-click on it and select Run as administrator.) In the Command Prompt window type (or copy/paste) the following lines one at a time. TAKEOWN /F C:\Windows\System32\drivers\bthport.sys ICACLS C:\Windows\System32\drivers\bthport.sys /grant administrators:F COPY /Y C:\Temp\bthport.sys C:\Windows\System32\drivers\bthport.sys NAC checks should now pass. _____________________________ Rob Biddle Network Systems Engineer / Administrator College of Mount St. Joseph From: Cisco Clean Access Users and Administrators [mailto:[email protected]] On Behalf Of Garro, Thomas Sent: Tuesday, August 16, 2011 3:47 PM To: [email protected] Subject: KB2566220 Hello All, We are having issues with KB2566220 were the CCA rule is checking for bthport.sys after 4/19/11. However, after install this update the file date and version never change. Is anyone else experiencing this issue or have a fix to resolve it? Thanks, Tom
