This issue has been solved. See solution.

I'm running Windows Server 2008 SBS with Symantec Endpoint Protection v12.

I installed the latest bout of Windows updates and now I'm seeing a dialog box pop up saying:

Local Security Authority Process has changed since the last time you used it.
Name: Local Security Authority Process
Application: lsass.exe

Do you want to allow it to access the network?

Name:  Local Security Authority Process
Version:  6.0.6002.18541
File Path:  C:\Windows\System32\lsass.exe

Connection Origin:  remote initiated
Protocol:  UDP
Local Address:
Local Port:  88 (KERBEROS - Kerberos v5)
Remote Name:      
Remote Address:
Remote Port:  3550

The remote address listed above is a regular Windows PC on my LAN, I don't believe any PC's are infected at this time. At least SEP isn't reporting anything as such.
The only updates I've installed are as follows:

Is this something that is okay to just proceed with?  I'm not clicking 'Yes' until I know more.
