This is a strange problem to be honest. More or less, there is a new, annoying log entry every 15 seconds in my vista logs about getting a new IP address. Pic below shows this clearly, i cleared the log and then these appeared. More and more spam over time. I've been suffering the odd BSOD/random crash (even at stock settings) and i'm wondering if this is to blame - i have updated all my network drivers (windows update first, then manually hunting for them) and the problem has not gone away. The two ACTIVE network cards, are a marvell yukon gigabit card and hamachi. Disabling hamachi doesnt make it go away, so i beleive it is the yukon card. Does anyone have any ideas what can cause this problem, or how to make it go away?
