Following services are running on my Windows 7 computer, would love it if somebody repeats this setup and then tries and connect to the computer from an outside computer/outside internet connection to see if it works:

Application Experience
Application Information
Base Filtering Engine
COM+ Event System
Creative Audio Service (soundblaster)
Cryptographic Services
DCOM Server Process Launcher
Desktop Window Manager Session Manager
DHCP Client
DNS Client
Encrypting File System (EFS)
Function Discovery Provider Host (normally this is off but was started manually apperently)
Group Policy Client

Network Connections
Network List Service

Windows Management Instrumentation manual

Perhaps this weird "can't connect to computer from outside" can be repeated with these settings.

Or perhaps some windows update screwed up winsock somehow so it's not working correctly anymore for when connections come from outside.
Or bit rott, though these last couple of hypothesis are unlikely.

One possible idea is to replace PC with for example laptop and repeat test procedure to see if it's indeed the PC at fault for connection failure.

Hmmm very strange situation for now.

(While writing this I had this idea: I could try booting linux if my DVD drive still working and run software from there, in case windows is biting me in the ass with these services, might attempt this later, would have to cross-compile to linux or use wine)

Bye for now,
