A short message in a blogbottle for future googlers. Some time ago, I added a user account to my Windows XP Service Pack 1 Dell 5100 laptop. When the machine boots, it asks me to log in. Fine. All works well.
Except when I happen to be using a dialup connection via USB. Then, randomly, the system crashes hard. Hard enough to require taking the battery out of the back style 'hard'.
Remove the user account - and the problem with dialup over USB goes away.
One of life's little mysteries.
Someday, someone out there may find this factoid interesting.
Personally, I'm happy to have my machine back stable enough to post this to my blog without the machine collapsing under me.
