The new version of Process Explorer shows network activity history, but it doesn't in one of my computers. This particular PC runs Windows XP SP3 and it has just been reformatted so everything is "fresh". I have even installed WinPCap and Microsoft Network monitor, in case some of these drivers were necessary, but the graph stays in 0.
Any ideas why this could happen?
I would ask in Sysinternal's forum, but I really don't want to register in yet another forum.
