While i haven't had that happen, try using the Event Viewer to see if DEP shows up in the logs. Right-click My Computer icon, select Event Viewer. Check each log for the DEP.
Thanks for the reply. I didnt have event viewer when I right clicked My computer but I did find it in administrative tools in the control panel. I will try to correlate the errors that I get when i boot up to the times and errors in the application and system event folders. There are a nunber of errors in both. In the system events there are DCOM, Service control manager, and other errors but much more than the number of DEP errors that I get when I boot up. Thanks again and Ill give you an update when I have more info.
