Hi I have a windows XP machine that is used to print labels from a Zebra label printer. It is connected a member of the domain. I am getting reports that when people try to use the computer it will sometimes be frozen to the point where they have to physically shut the machine down and boot to get it responding. (this happens about once a day).

I took a look in Event Viewer and nabbed some of these errors out of it:

I'm not really sure what to make out of this...

Thanks for the help in advanced,
