DCOM Error 10010 - Very Slow Login, Very Slow Desktop
Greetings to all, although there are many posts on the internet about this issue, even a remedy that appears to work, I need to know the cause of this problem: I have several Windows XP SP2 machines, which had McAfee anti-virus, and we are now in the process of installing Symantec Endpoint Protection. The previous software is always removed first, before installing Symantec's. There is usually no problem, but some machines have developed a symptom that appears randomly; it can happen 1 week after installation, it can appear 1 month after installation. The logon process takes a lot of time (sometimes around 10 minutes), before the desktop fully appears. Using the Start Menu or the Taskbar (same is to say, explorer.exe) also is full of delay. Clicking on any item only triggers the action 2 or 3 minutes after. Yet, if you click anything from the desktop, it promply executes. In fact, I can open a command prompt, and do all the commands I need, and open event viewer, task manager, etc, without any problem. It seems to be connected to the explorer.exe process. In the Event Viewer, the explanation seems to be showing as DCOM access timeouts. All the machines with these problems show Event ID 10010, with the following descriptions:The server {8BC3F05E-D86B-11D0-A075-00C04FB68820} did not register with DCOM within the required timeout.The server {5CEC0E13-CF22-414C-8D67-D44B06420FC1} did not register with DCOM within the required timeout.The server {BA126AE5-2166-11D1-B1D0-00805FC1270E} did not register with DCOM within the required timeout. The first Class is WMI, the second Class is SavInfo (likely Symantec), and the third is Network Connection Manager Class. When the computer is in this state, restarting, uninstalling Symantec Endpoint Protection (even manually, since sometimes the Add/Remove Program console is also non-responsive), doesn't seem to work. The only option was to format and reinstall. There's a solution here that seems to remedy this problem, but i can't figure out what is the problem. My only pointer is that I installed Symantec Endpoint Protection on these machines. But on the other hand, I have this AV installed on many machines, all of them working smoothly. This problem only seems to affect Windows XP, SP2 and SP3 alike. Windows Vista and Windows 7 are not affected. I ask anyone with more data than this, and who already figured it out, to please respond. For what I have gathered, this is a permissions issue on the registry, as explained athttp://blogs.msdn.com/b/distributedservices/archive/2009/01/21/dcom-error-10010-in-the-event-logs-and-sluggish-server-performance.aspx Thanks everyone for reading, I hope this helps some, and I wait for a cause, so I call rollout Symantec without worries.

I am loolking at the same error and it is a big problem on start up....my error started shortly after rebuilding the PC. At that point I had performed some Windows updates, nstalled Visual Studio and SQL Server. I also had one device attached other than keyboard/mouse - an external hard drive.Have we anything in common? I think the problem is introduced with Windows updates....PG
