I just ran DCdiag on one of my DC's and found the following warning:

C:\Windows\system32>dcdiag /q
Warning: Attribute userAccountControl of is:
0x82020 = ( PASSWD_NOTREQD | SERVER_TRUST_ACCOUNT | TRUSTED_FOR_DELEGATION )
Typical setting for a DC is
0x82000 = ( SERVER_TRUST_ACCOUNT | TRUSTED_FOR_DELEGATION )
This may be affecting replication?

So, where did this come from?

After some looking, I found the following:

There are a few ways to uninstall an MSI package.

• If you have access to the original MSI used for the installation, you can simply right click it in Windows Explorer and select Uninstall.

  msiexec /x filename.msi /q

We were faced with a nice little challenge recently here.
The normal rule about mailboxes in Exchange is simple and fairly obvious: one user, one mailbox, and vice versa.
Or that's what I always learned...

Now, we have an account which normally logs in 2 or more times (our reception desk).

There is a simple solution to this:

- Create the extra account(s).

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
