Hi, I have two problems with windows server 2008, please help: 1. HDD slow access I installed 7 windows servers 2008 on 7 IBM 3650 M2 3 months ago, everythins was OK at that time. But now when I access hard disk or folder (on 7 servers), I get 30-60 seconds in not responding. (CPU usage 15%, no more processes running, two hard disk running in Raid1, 2 CPU 2.0 Ghz, 8GB RAM, Installed Software: Kaspersky, Visual studio, Visual Sourcesafe, Opmanager) How can I check or any suggesion? 2. DCOM error I installed veritas 6.5 software on one IBM server, i get DCOM error: Log Name: System Source: Microsoft-Windows-DistributedCOM Date: 4/28/2010 11:47:18 AM Event ID: 10016 Task Category: None Level: Error Keywords: Classic User: SYSTEM Computer: AD.com Description: The application-specific permission settings do not grant Local Launch permission for the COM Server application with CLSID {24FF4FDC-1D9F-4195-8C79-0DA39248FF48} to the user NT AUTHORITY\SYSTEM SID (S-1-5-18) from address LocalHost (Using LRPC).

Run Reliability and Performance Monitor on the server to identify the issue. Here is a good reference article: http://technet.microsoft.com/en-us/magazine/2008.08.pulse.aspx DCOM Error – Try these options: http://support.microsoft.com/kb/920783 http://support.microsoft.com/kb/931355 Santhosh Sivarajan | MCTS, MCSE (W2K3/W2K/NT4), MCSA (W2K3/W2K/MSG), CCNA, Network+ Houston, TX http://blogs.sivarajan.com/ http://publications.sivarajan.com/ This posting is provided "AS IS" with no warranties, and confers no rights.

I see a lot of ways on how to get rid of the error message, but not on which way is the "right" choice. Also, a lot of attempts for an explanation can be read, but not the whole story. I have written an article about this error message, with the full story of what and why and which possible solutions there are and which one is the best for you. It's a long article with a lot of side notes, but I think you need at least a little bit of background information to know what you're talking about and what you're doing.
