Here a new little powershell script that creates an event 6970 in the event viewer when there is more than X accounts locked in less than Y minutes. Now, you just have to create a new rule in SCOM that collect event with the ID6970 and schedule that script to run every 10 minutes.

Thanks to that you can be alert when there is an attack attempt to your Active Directory.

Some weeks ago, I had to deploy SCOM Agent on more than 350 windows servers at the time. For that, I wrote a PowerShell Script where you just have to give a server list in input and the name of your RMS/MS . And that’s it, the script is performing the agent installation for you. A CSV file will be generated as output with the agent installation status of each servers.

Concerning the right management, you have to ensure that the Default Action Account using on the server that you will use for deploying the agents (MS normally), has administrative right on the servers that you want to add in SCOM. For that, and the duration of the deployment only, use a Domain Admin Account as the Run As Account of your MS/RMS.

The script :

There are two ways to solve this problem, you can recreate the /dev/random file or do a manual agent install.

For both fixes, clean off the partially installed agent using the commands

  1. rpm -e scx
  2. rm -rf /etc/opt/microsoft/scx

Then if you want to make it so that discovery will work from the wizard use the commands

  1. rm /dev/random
  2. mknod -m 644 /dev/random c 1 9
  3. chown root:root /dev/random

A manual install requires copying the appropriate package from %Program Files%\System Center Operations Manager 2007\AgentManagement\UnixAgents to the Unix\Linux machine and installing it directly.

After fixing the install issue, switch the /dev/random file back to a signed random file using the commands:

  1. rm /dev/random
  2. mknod -m 644 /dev/random c 1 8
  3. chown root:root /dev/random

En tant qu’utilisateur de Microsoft System Center Operations Manager 2007, vous avez déjà certainement été confronté au problème ci-dessous

 A computer agent unexpectedly generates heartbeat alerts after you put it into Maintenance mode in System Center Operations Manager 2007

La description détaillée de cela se trouve sur le site de Microsoft : http://support.microsoft.com/kb/942866

En fait, pour mettre un serveur en Maintenance Mode, il faut mettre en réalité trois objets en Maintenance :

  • Computers
  • Health Service
  • Health Service Watcher

Plutot que de faire cela à la main à chaque fois que vous souhaitez mettre un odirnateur completement en Maintenance Mode, voici deux scripts que j’ai écris.

Et voici comment appeller ces deux scripts

Start maintenance mode
 C:\WINDOWS\system32\WindowsPowerShell\v1.0\powershell.exe C:\MaintenanceMode\StartMaintenanceMode.ps1 –rootMS: ‘localhost’ -computerPrincipalName: 'SERVERNAME' -minutes:30 -comment: 'Maintenance Mode' -reason: 'PlannedOther'
Stop maintenance mode
 C:\WINDOWS\system32\WindowsPowerShell\v1.0\powershell.exe C:\MaintenanceMode\StopMaintenanceMode.ps1 –rootMS: ‘localhost’ -computerPrincipalName: 'SERVERNAME'

Voilà, si vous avez des questions, ne pas hésiter à les poser dans les commentaires.
