DCOM Errors

[Mike Jones 2]

DCOM 10021 12/21/2007 07:00 75 *
The launch and activation security descriptor for the COM Server application with CLSID {486DD18C-B031-4586-AAF1-C1A92C57E4CC} is invalid. It contains Access Control Entries with permissions that are invalid. The requested action was therefore not performed. This security permission can be corrected using the Component Services administrative tool.



I frequently get over 100 DCOM errors a day on a number of our servers, anyone got an answer as to why, or how i can stop these?

What is the model of the server hat you are using ?

You could try to update the PSP(Proliant support Pack) on your server

Select the server model and OS in the following link
