Windows 2003 DHCP Server MP RRS feed

  • Question

  • Under Windows Server > DHCP Server I selected Microsoft.Windows.2008R2.DHCP.Server and installed it.

    We have 3 DHCP Servers.  2 DHCP servers are running Windows 2003 OS Server adn 1 DHCP is running Windows 2008R2.

    I don't see a DHCP MP for Windows 2003 Servers??? 

    I am getting these emails:

    The Windows Event Log Provider was unable to open the Microsoft-Windows-Dhcp-Server/FilterNotifications event log on computer 'dc004.contoso.com' for reading. The provider will retry opening the log every 30 seconds.

     

    And it is referring to DHCP Servers running on Windows 2003 Servers.

     

    How do I go about addressing this issue - Advise Please.

     

    Thank you

  • "There is a side effect of this MP, when it discovers older versions of DHCP on Server 2003. There are two rules that are trying to open an event log that does not exist on Windows 2003 and older DHCP servers. This causes the agent to throw “Failed Accessing Windows Event Log” alerts and spams the event log on the agent with 25002 and 25004 errors. You should consider setting these to disabled for non-Windows 2008 DHCP servers or we will log these errors and turn the Healthservice for those agents to a warning state. You should disable these rules for all non-2008 DHCP servers, or better yet – just disable these across the board as they are just event collection rules and we likely don’t need/want these in the OpsMgr database anyway. These rules are: ◦Rule for event collection - Link Layer based filtering ◦Rule for event collection - DHCP server configuration changes" From Kevin's blog

  • Hi

    You can't tartget rules and monitors at groups - you need to target a class. I have info on this here:

    Have you looked through Kevins suggestions here for the DHCP MP:

  • These 2 rules ..

  • Rule for event collection - Link Layer based filtering
  • Rule for event collection - DHCP server configuration changes

    The rules are greyed out when I visit them - the disable option is greyed out too, I guess I will have to create a new MP and use overrides?  or how do I disable these 2 rules

  • Thanks,

  • I believe this is a known issue with the 2K8 R2 mp.  It  discovers older DHCP servers that are no longer in mainstream support.  To address this and prevent the MP from discovering those old servers, scope the 2K8 R2 servers into a computer group, and enable the discovery on that group, while creating a global override that disables the discovery.  This will make it so the MP only discovers the actual supported servers

  • Hi

    This is a particularly shoddy management pack. Kevin Holman does his usual great explanation of all the pitfalls with it here:

    Quote "Be aware – this class discovers ALL DHCP servers, not just 2008R2 and the class name would lead you to think: "

    Good Luck!

  • Thanks for your input all.


    Dan:

    I created a new MP (copied the existing Windows 2008R2 DHCP MP)

    I created a new group, assigned the new MP to this group and added my windows2008R2 DHCP servers in there. 

    How do I enable the discovery for this group and create a global override so the discovery is disabled for Windows 2003 DHCPs?

    Advise Please... Thanks
