Hello Im new here.. =D Im an I/T director Server Admin Network Admin =D you name it. Anyway, Ive noticed on a lot of workstations areound our networks running Vista Business and Ultimate that if you disable the Desktop Window Manager service and manually stop it, it resolves this problem on most of our machines. My only simple explanation I can come up with is this. I Beleive the DWM actually eats up a lot of memory and resource on the processor. In fact if you have ever noticed your computer running and the Processor Fan going nonstop that is an indicator that your chip is heating up (NOT OVERHEATING BUT HEATING UP AS IT SHOULD) and the fan is cooling it. This will only happen when the processor starts doing some actual work. 98.9 percent of the time its the DWM. And the DWM is just running away and heating that Chip up constantly while you are using the workstations. But funny the computer is silent when no one is on it but it is still on. (No Windows to manage no need to run =D) Any way I belevei that this resource Hogging and the fact that windows is generating a error to the log reporting service etc, think just casues a cache or memory conflict. I dont think there is any relevance in the DWM to the actual 15016 Error but I do believe the resource utalization on both the Kerberos Auth Error and the DWM is too much.. I have also noticed that this is not so much of an issue on all of the Dual Core Machines we run. Usually happens more on the Prescott P4's and AMD X64 Chips.. And Im pretty sure that it becasue the Dual Core processor's disperse the resources evenly as opposed to the single core. But i can tell you that on every machine this happens on, I go in and disable the DWM and no more crashes and freezes. The error is still in the log but the spuratic freezes cease. Therefore i believe it is not the actuall error or the Kerb. Auth Service causing this but it is the DWM. Hope this helps Good luck. Paul Good Luck hope this helps....
