DCOM event 10016 cannot change permissions in Component services

by on Oct.30, 2010, under Microsoft

I wrote about this event before here: dcom-event-10016 but this time it was bit different.
Even though I was changing the permission for the object in Component services the permissions were reverting back after couple minutes to what they were and it was resulting that the event 10016 was generated again. Apparently after applying some MS update the permissions on some Windows sub folder are changed. Specifically the permissions were changed on ‘%windir%/registration‘ folder(usually c:\windows\registration). Check the permissions of this folder and make sure that System user has full rights after that try changing the permissions on the object in Component services and see if it stays this time.

DCOM Event 10016

by on Oct.28, 2010, under Microsoft, SCCM/SMS2003

Here is one of the Event errors that I’ve got on one of the SCCM servers.
Source: DCOM
Type: Error
Event ID: 10016

The application-specific permission settings do not grant Local Launch permission for the COM Server application with CLSID
{A8889E84-14D9-43D0-813A-249BFFE193C2}
to the user domain\useraccount (S-1-5-21-1957994488-1004336348-839522115-9143).  This security permission can be modified using the Component Services administrative tool.

Hardware Reserved Memory in Windows 7 Part2 for 32Bit

by on Oct.13, 2010, under Microsoft, Windows 7

I’ve found this interesting article about how to make Windows 7 32bit to use as much ram as possible. Even when you have over 4GB.
I’ve tried it on one of the test laptops and it worked. It have not crashed on me but I cannot tell you how stable it is as it is a test laptop. Performance wise it seems to perform more or less  the same but I’ve noticed that the hard drive is used less as the files are cached in RAM. So in theory laptop should be faster.
Use it at your own risk: Windows 7 32-bit with full 4 GB or 8 GB RAM support

Hardware Reserved Memory in Windows 7 Part1 for 64bit

by on Oct.08, 2010, under Microsoft, Windows 7

The other day I’ve been using photo editing application and noticed that my laptop was struggling. Quick view in Task manager revealed that I running out of memory but the interesting thing was that total amount of physical memory was less then I expected. So next I popped up Resource Monitor and clicked onto Memory tab. This revealed that 561MB was Hardware Reserved.

The last thing to check was Basic system information in computer properties. In there it said:
Installed memory (RAM): 4.00 GB (3.45 GB usable)

Network Node Manager (NNM) authetication using Active directory

by on Oct.07, 2010, under HP, NNM

HP monitoring software like Sitescope, BAC, SIM, NNM etc. are using build in authentication. This is fine but that means that you have to remember many different passwords and logins. The other thing is that many companies have password policies and these policies must apply to all systems. So the obvious thing to do, would be to use one login provider. For this reason many use  Active Directory. In HP SIM configuring authentication through Active Directory is very simple using GUI. Unfortunately in Network Node Manager (NNM) it is not that simple. The information is provided in Deployment Reference document but it is not very clear.

In this post I’ll show you what works for me. (continue reading…)
