Hey guys, revently I have encountered the following app alerting my firewall to its precence- winlogon.exe
I'm a bit concerned it might be something untoward.
Anybody know what this is for and why some programs are asking for access to it and/or for it to access the internet? My firewall picked it up trying to access the net, so I denied it access as its never asked before.
Programs which have since activated an associated firewall warning with this app:
- messenger
- sniper elite (game)

Up to date virus scan with nortonAV 2005, spybot, adaware etc everything checks out fine. I've done some checking on the net and it would appear that this is a legitimate part of windows operation:

The Windows Logon Process is responsible for managing user logon and logoff, and checks the Windows XP activation code. Must be in system32 folder

Suspicion should only arise if the following occurs:

WINLOGON is the windows compenent, winlogin.exe is not. The below link is what I used to fix it...my firewall caught it trying to connect to the internet, if it cant it seems harmless. A well problem solved for me. See also: Link

I've searched my HD and this app only occurs in the system32 folder (legitimate windows app location?) and nowhere else.
Anybody know anything more about this?
