I found a nice site with training clips for people who want to learn more about Exchange 2007 / 2010.

It's called http://www.exclusivelyexchange.com/

When we reboot our SCOM server, we get an error message 'SDK SPN Not Registered'

After a quick search on the internet, I found the solution to this problem on the site of Jonathan Almquest: http://blogs.technet.com/jonathanalmquist/archive/2008/03/12/sdk-spn-not...

And another problem gone.

Troubleshooting high memory usage on the PC's here...

using http://blogs.msdn.com/tess/archive/2008/02/19/high-memory-usage-with-use... I found out that ddraw.dll is using that 382MB of memory, which is not going to work on a very old machine with just 512MB ram :)

Let's check where this problem comes from.

I was looking how to create dependencies in SCOM 2007 when I stumbled upon this article on TechNet:

Always nice to know :)

Yes, its true, Cisco virtual networking goodness is available to one and all. To kick things off, we have worked with the fine folks at VMW to put together a 60-day eval program so you can check things out in your own environment. As a quick reminder, you will need a (free) cisco.com account to access the software (don’t worry, we won’t spam you).

Head over to https://www.vmware.com/tryvmware/ to get your 60-day vSphere 4.0 eval license
Go to http://www.cisco.com/go/1000v to access the design, install and upgrade guides—look for the “Support” box on the upper right part of the page

In addition to VMware’s announcement that vSphere 4 is now generally available, VMware is also pleased to announce that as of May 21, 2009 the vSphere vShield Zones product is also generally available. VMware vShield Zones 1.0 offers the following key features and benefits for vSphere 4 environments:

Central Management of Logical Zone Boundaries and Segmentation

* Leverage existing virtual infrastructure containers – hosts, virtual switches, VLANs – as logical trust or organizational zones

I've been playing with HP Systems Insight Manager (HP SIM) 5.3 on a Windows 2008 VM, 64 bits.

I ran into a couple of problems:

Remote Support wouldn't register.

In the logfile "...\Hewlett-Packard\RemoteSupport\logs\iseeclient.log" the following is recorded:

20090522T10:38:27 | IseeClient | info | ConfigManager.cxx:365 | Data source has been set to hpsim, using e:\Program Files (x86)\HP\RemoteSupport\config\clientmanager.hpsim.cfg as client config file.
20090522T10:38:55 | IseeClient | always | TPMListener.cxx:232 | Received IPC to submit transport item to the queue.

When trying to install Altiris Deployment web console on a server running IIS7 we ran into some problems:
Webconsole gives an error 500.24
An ASP.NET setting has been detected that does not apply in Integrated managed pipeline mode.
It occurs because ASP.NET Integrated mode is unable to impersonate the request identity in the BeginRequest and AuthenticateRequest pipeline stages.
Workaround:

I’ve been testing with the experimental feature Virtual Machine High Availability(aka VM Failure Monitoring) for a couple of days now. I must say it just does what VMware claims in the PDF, resetting a VM within the configured time when a the heartbeat is lost. But one thing that struck me is that there’s hardly any evidence that HA did it’s job, in other words no events logged in VirtualCenter as far as I can see. Well there was an error indicating something was wrong “Remote console on w2k3-001 disconnected”.
