Authenticate SCOM console on a proxy

September 27, 2012

When going to client environments I often face this issue: internet access is only possible when authenticating against a proxy. Now, this is especially a problem when you want to be able to download management packs using the SCOM console, or at least check whether you are up-to-date.

Following a hint of my collegue Thomas Vuylsteke (see his excellent blog at http://setspn.blogspot.com/), I quickly found the “proxy configuration” page on MSDN, stating that it is possible to configure proxy utilization in the .exe.config file: http://msdn.microsoft.com/en-us/library/dkwyc043.aspx

This is actually a quick fix:

On SCOM 2012, open C:\Program Files\System Center 2012\Operations Manager\Console\Microsoft.EnterpriseManagement.Monitoring.Console.exe.config

Add the following code:

<system.net>
<defaultProxy enabled="true" useDefaultCredentials="true">
<proxy usesystemdefault="True" />
</defaultProxy>
</system.net>

The bottom of your config-file should look like this:


En now it is possible to use the online catalog!



A quick fix for a nasty issue! I didn’t test it yet for the SCOM 2007 R2 console, but I’m pretty sure it will also work for that version.

UPDATE: apparently, the quotes didn’t pass very well in this blog post. I updated it so now you should be able to copy-paste the code.

UPDATE2: I confirmed that this works with non-MS proxy servers.

SCE 2010 Installation error: This instance cannot be used for the Essentials database

January 30, 2012

When will you be faced with this problem?

  • New installation of SCE 2010
  • WSUS is already installed using an existing SQL server standard for its database

Problem description

When installing System Center Essentials 2010 for a client I faced the following error: “This instance cannot be used for the essentials database because it does not contain the windows server update services database”.

As you all know, WSUS needs to be installed on the SCE server. I knew the instance hosted the WSUS database. The problem is, that the SCE installer looks at the following reg key to locate the database server that is used by WSUS:

  • HKEY_LOCAL_MACHINESOFTWAREMicrosoftUpdate ServicesServerSetupSqlServerName

When installing WSUS, it will enter the FQDN of the SQL server in this registry key. The SCE installer can only cope with the NETBIOS name, which results in the error above.

The solution

How to solve this issue? Replace the FQDN by the NETBIOS name in this registry key:

  • HKEY_LOCAL_MACHINESOFTWAREMicrosoftUpdate ServicesServerSetupSqlServerName

And now bye bye installation error!

Ow yes, do not forget to not select “use microsoft update or installation” further on in the wizard or the install will fail. Long live bug-free installers J.
