In short, YES! i have started to see this very same thing. 1 MS client i have is getting this when they
are trying to loggin and its throwing this error. It is generated when they are being authenticated
though. Problem is there username and password hasn't changed, and they were able to get in before with
no problem. They are running NT with service pack 6a. Not sure whats the deal with that 1 client tho..
