HI, I heve W2K sp4 with terminal services installed and all security updates installed too, but and DCOM error still logged on system log many time when I'm connect to the server via Terminal Server (TS administrator mode). This is the error: Event Type: Error Event Source: DCOM Event Category: None Event ID: 10010 Date: 3/20/2006 Time: 08:57:23 AM User: Domain\administrator Computer: ServerName Description: The server {E9376CC6-121A-447E-81CF-D8BCC200007C} did not register with DCOM within the required timeout. I have try to apply many KB from Microsoft support, but the error still logged. If I stop the automatic update service the errors stop. I have configured the server to use the wsus. How to do I to solve this problem?
