I have recently set up a wireless network at home and after getting some great advice on this forum its all running fine (fingers crossed)
I think I was advised (by ade.h who was very helpful in solving my problems) to allow NetBIOS and universal plug and play and now if i run a security check Macafee firewall reports "possible" problems because these are allowed. I dont understand what NetBIOS or universal plug and play are, so dont know if allowing them is a security risk that I need worry about or if there is anything else I should be doing. Thanks to anyone who can help
Run the Services console (services.msc) and you'll see all of them. Windows' own services have descriptions - there will be some others from certain programs.
But rest assured that the two services that you describe are Windows components (notwithstanding the possibility that malware can spoof them). UPnP is optional in many systems, but NetBIOS is essential in any network.
