I have one user that is experiencing this problem.
About twice a day she gets the following message from Win XP

runtime error in visual c++ runtime library wmiprvse.exe

To troubleshoot the problem, I tried preventing the WMI service from
starting automatically. Doing so fixed the pop-up error message from
showing but it also prevented CLNTRUST from running.

Again, I only have 1 out of 80 users experiencing this issue... any ideas?
