First of all, sorry for my English!
I made a clean install, Windows XP x64 SP2, drivers (x64), NOD32 (x64), CFP3 (x64), Diskeeper 2k8 (x64), no any other program.
When I finished all install, I tested on grc.com (ShieldsUp!). It shows port 1025 is open (used by lsass.exe), port 1033 is closed (used by diskeeper), other ports are stealth.
When I shutdown Diskeeper server, port 1033 is stealth.
What does lsass.exe make? How can I shutdown it? In Task Manager I can't: "This is a critical system process. task Manager cannot end this process."
I can't find it (hidden files are showed), but in CFP3 --> "View Active Connections" this is the path: c:\windows\system32\lsass.exe TCP, Listening: 1025, Bytes In 0 / Bytes Out 0
My internet connection is cable.
