DHCP Split Scope Monitoring

Hello :
I have an interesting scenario where I need to setup some kind of monitoring around DHCP Scope exhaustion. Now each site has two DHCP servers with the Scopes split. So If I setup event log monitor and one server reports that a scope is running out of IP
addresses, it does not mean that the second server is also running out of free IP. Is there a way to use SCOM to monitor both DHCP servers and alert if the scope is out of free IP on both servers? There is a nice article on this for Solarwinds - https://thwack.solarwinds.com/docs/DOC-174909
but I would like to achieve this using SCOM.
PS: I know IPAM can be a good solution, but I am really interested in ways to do this using SCOM and I am open to any scripted solution or custom MPs.
Any pointers will be highly appreciated.

Hi,
How about using an aggregate rollup monitor to group multiple monitors into one monitor and then use that monitor to set the health state and generate an alert.
Or Dependency Monitors with Percentage policy set:
http://technet.microsoft.com/en-us/library/hh457606.aspx
In addition, would suggest you look at DHCP failover in WS2012, which opens up some new options for HA design.
DHCP failover: This feature provides the ability to have two DHCP servers serve IP addresses and option configuration to the same subnet or scope, providing for continuous availability of DHCP service to clients. The two DHCP servers replicate lease information
between them, allowing one server to assume responsibility for servicing of clients for the entire subnet when the other server is unavailable. It is also possible to configure failover in a load-balancing configuration with client requests distributed between
the two servers in a failover relationship. For more information about DHCP failover, see Step-by-Step:

  • DHCP Split-Scope Configuration Wizard showing error "Not enough storage is available to process this command".

    Hi,
    I'm trying to split the DHCP scope between two Servers using the DHCP Split-Scope Configuration Wizard.
    Server one is a VM hosted on Hyper-V and is running Windows Small Business Server 2008 (I think this was previously SBS2003 and was upgraded at some point in time). The whole DHCP scope is currently configured on here.
    Server two is a VMware VM running Windows Server 2012 R2.
    I've installed the DHCP Server role on Server two (2012R2) and authorized the Server. When I launch DHCP Manager, add the SBS2008 Server in the MMC, right click the scope and choose "Advanced > Split-Scope", and then run through the wizard,
    I get as far as the "Percentage of Split" screen, and when I click next I get the error "Not enough storage is available to process this command".
    I've searched online for this particular error message and I've come across articles suggesting AV exclusions are not in place for the DHCP database and files, however in this case the exclusions are definitely in place and I've also tried completely disabling
    AV on both Servers and this made no difference to the outcome.
    I also came across articles suggesting the "IRPStackSize" registry DWORD needed to be added and set to a decimal value of 15 or larger. Again, I've tried adding this and rebooted both Servers but I get the same result.
    Anyway have any ideas?
    Thanks,
    Craig

    Hi Eve,
    No, there were no related events in the event logs. I've since tried splitting the DHCP scope manually but this did not work - the DHCP Server on the SBS would just stop and event: 1053 was displayed when trying to start the service again. I noticed
    that as soon as I de-activated DHCP Server on the 2012 Server then the DHCP Server on the SBS would start again.
    I then found the following in a TechNet article that would suggest I cannot have another DHCP Server on the network if using Small Business Server.
    Notes      
    A DHCP server running Microsoft Small Business Server will not operate if another DHCP server is active on its network.
    Detection of unauthorized DHCP servers requires the deployment of Active Directory Domain Services and the DHCP service. Other DHCP servers do not attempt to determine whether they are authorized by Active Directory Domain Services before offering IP address
    leases.

  • DHCP Split Scope - Scope Full

    Good Morning,
    I have 2 DHCP svrs offering split scope on more a 50/50 type bases (no delay).... I'm wondering if one DHCP svr runs out of addresses will the second svr's range cover the request?
    I see all this configuration as more a one server is down the other covers, I'm not really sure how it handles things like a range out of addresses... I know the device would send out a DHCP request and the fastest responding server wins but if one server
    can't offer an address does it reply with anything?
    Thanks All
    Paul

    Hi,
    Summary of the conversation (about generating IP lease) between client and DHCP server:
    Client - DHCP discover: ask for IP lease.
    DHCP server - DHCP offer: populated with the IP address the server is offering the client.
    Client - DHCP request: specify which offer(IP) it choose, and ask for detailed information about this IP.
    DHCP server - DHCP ACK: detailed information about IP lease send to the client.
    When a client send discover packet to ask for a lease, all DHCP server which can receive this packet will answer with offer packet. If the DHCP has ran out of IP address or down, it will not broadcast offer packet.

  • Swapping DHCP Split-Scope

    Hi all,
    I have a site with 2 DHCP servers, one in production environment and another in DR. For whatever reason, the DR server was setup to server the majority of the DHCP leases (10.50 -> 10.209) and the production server only 30 addresses (10.210 -> 10.240).
    We want to change this around and I have a couple of questions:
    1. Our documented process is to remove the exclusion ranges and then setup new exclusion ranges as a complete opposite of the current setup to give the production server the majority of the leases.
    2. What happens to active client leases e.g. Client connected on the DR scope, lets say 10.100. When the ranges are switched over, presumably 10.100 will then become available on the production scope and will be dished out to a new client but the old client
    will receive an IP conflict error OR is DHCP smart enough to know this?
    Any help would be appreciated.
    David Robertson

    Hi,
    I suppose the main purpose is to extend IP address pool of your product. If so, I think we can shrink the IP pool in DR, then we should wait until the lease is expired. As
    you referred, we can reduce the lease time first. Once the lease is expired, we can enlarge another DHCP pool.
    Since you have two DHCP for one network, how do you determine which computer to get an IP from production network? Do you have DHCP reservation for them? Personally, I think
    configure two subnet and router between them could be a better choice.
    Hope this helps.

  • DHCP: Splitting 10.10.120.0/23 between 2 servers, why exclude?

    I understand that best practice is to split a scope between 2 dhcp servers on the same subnet.  We have a rather larger subnet 10.10.120.0/23
    Server1 with pool 10.10.120.50-10.10.120.230
    Server2 with pool 10.10.121.50-10.10.121.230
    What's the purpose of expanding the scope in each server and configuring exclusions?  If each server have technically a different subnet, there will never be a conflict.  I would like to know if there's any benefit to expand the range and add exclusions.
    Server1 with pool 10.10.120.50-10.10.121.230 exclude 10.10.120.231-10.10.121.230
    Server2 with pool 10.10.120.50-10.10.121.230 exclude 10.10.120.50-10.10.121.49

    If this is your config:
    Server1 with pool 10.10.120.50-10.10.120.230 /23
    Server2 with pool 10.10.121.50-10.10.121.230 /23
    Then those are NOT different subnets.  Those are properly split DHCP scopes.
    The subnet in this case is from 10.10.120.0 - 10.10.121.255 and that is what you're splitting.
    For your second example:
    Server1 with pool 10.10.120.50-10.10.121.230 exclude 10.10.120.231-10.10.121.230
    Server2 with pool 10.10.120.50-10.10.121.230 exclude 10.10.120.50-10.10.121.49
    This will give you problems:
    1) The servers are offering the same IPs, they might even issue the same IP to two different devices because they won't know the other gave it away.
    2) Server 1 has some exclusions that Server 2 won't know about.  That means Server 2 will issue IPs from Server 1's exclusion range.
    3) This is not a recommended setup.

  • Preview issue - scope monitor

    hey all - i have color 1.0.4 - i bought a new imac i7 - intel quad core - because my power mac g5 was so slow it was killing me - SO i go to load my final cut studio 2 (works great) except for the color program (1.0.4) everything is fine except the preview in the scope viewer - it is this crazy red, blue thing that looks like its some sort of weird color waveform thing - the thumb nails are all normal - the still store images are normal until I try and bring them up in the preview viewer window - anyone have a clue:
    few more details: files are apple prores, graphic card is - ATI Radeon HD 4850 512 Vram
    thanks adam

    I think what asantelli might have been referring to is something else--an issue I'm having as well, where the Preview pane in the Scopes window does not display a regular image, but rather various colors overlaid on the image. It's somewhat reminiscent of the "False Color" feature on the Red & some monitors--that is, highlights come up red & yellow, etc. However, most of the image is black.
    I also am using an ATI Radeon card and Color 1.0.4. This issue is really annoying as it makes the Video Preview pane almost completely useless, and although I am monitoring through an MXO2 Le to an external monitor, I'd like to be able to see the Video Preview window for setting up secondaries, etc.
    Has anyone else had this issue, and, if so, do you know how to fix it? Thanks in advance.

  • How to split one monitor into two, differently configured desktops

    Hello,
    I have a 27" iMac. I would like to split the screen into two differently configured desktops or monitors. Apps like TwoUp or Divy don't exactly do this. I'll explain it with an example:
    Suppose I'm working on a document and I need to open many folders to retrieve files. One common problem is that opened folders overlap each other and sometimes they overlap with the document I'm working on, or they go underneath the document. I would like to split the screen vertically in, say, two virtual, independent desktops/monitors, like this:
    - one window/space on one side (say, on the left) of the screen would contain the document  from top to bottom, with no dock bar on the bottom
    - the other window/space (right) would behave as a regular, full desktop, with the entire dock on the bottom
    In this way, if I need to navigate to find a file to use in the document, I would move the cursor to the right. The Finder would work only in this window/space, thus windows or other applications would never overlap or clutter the left side of the screen. Drag-and-drop from right to left should be possible.
    One way to imagine it is as if the 16x9 monitor were comprised by two vertical, 8x9 independent monitors side by side, each with its own configuration.
    Is this possible? Can anyone recommend an application or type of setup?
    Thank you,
    -celso

    Looking for something like this?
    You can tell Display Maid to save the positions of your open windows across many apps and later restore those positions when things become a mess. With Display Maid you don’t have to restore windows one at a time, or even one app at a time. Display Maid restores all saved window positions across all apps with one command. It will also restore window positions automatically when it detects a workspace change.

  • Cannot remove file menu from split screen monitors.

    Hello, I installed the latest update from Apple which was the new Safari 7. I run 2 added monitors with my iMac being the primary. After update installed, both of my split monitors have the file menu on the top of the monitors. I went into the system menu under display and everything is as it should be yet I cannot remove the file menu from my secondary monitors....

    Thanks for the info however this still didnt solve the issue. I unselected and closed window but no changes were detected. I re opened the mission control and the box was selected again. I still have the file menues on both secondary monitiors. After i installed the latest update from apple, the one with the new safari update, is when i started having this issue. Everything worked fine before. My computer seems to be runing much slower now and when i click to open safri, it takes about 40 seconds to open safari..On both secondary monitiors, the file menues operate as if they are the main monitor, which my imac should be operating as the main....This is anoying...

  • Split 4k monitor into two "virtual monitors"?

    Hi all,
    I'm thinking of buying a 4k monitor to replace a dual-screen setup. However, I like the functionality of having two things maximised at once. Is there any way to set up X so that it sees the 4k 3840x2160 monitor as two separate 1920x2160 monitors? That way, maximising an application would only take up half of the physical screen and the taskbar would only appear on one half.
    Thanks!

    Hi,
    Yes, nearly all my laptops work that way. What is the Operating System on your machine ? The following setup is for Windows (Vista, Windows 7, Windows 8 & Windows 8.1):
    (a) Right click a blank space on desktop and select Personalize,
    (b) Click Personalize,
    (c) Click Display
    (d) Select your external Display (1 or 2)
    (e) Click use this display only.
    Depending on your machine, you may have to start to logon before the machine redirects display to external screen.
    Now my wuestion: what do you mean by REMOVE ?

    Hi,

    Process of Migration DHCP Server 2008R2 to Windows 2012
    • Firstly, you can disable the DHCP role in Windows Server 2008 R2. However, if the Windows Server 2012 is down, the clients cannot renew their IP lease duration and obtain IP address.
    Therefore, it is recommended to leave the DHCP role in Windows Server 2008 R2 and deploy high availability. Windows Server 2012 brings the new feature: DHCP failover. However it requires both DHCP Servers are Windows Server 2012. Consider another Server
    is Windows Server 2008 R2, we have to choose one of the following:
    >> DHCP in a Windows failover cluster. This option places the DHCP server in a cluster with an additional server configured with the DHCP service that assumes the load if the primary DHCP server fails. The clustering deployment option uses a single
    shared storage. This makes the storage a single point of failure, and requires additional investment in redundancy for storage. In addition, clustering involves relatively complex setup and maintenance.
    >> Split scope DHCP. Split scope DHCP uses two independent DHCP servers that share responsibility for a scope. Typically 70% of the addresses in the scope are assigned to the primary server and the remaining 30% are assigned to the backup server.
    If clients cannot reach the primary server then they can get an IP configuration from the secondary server. Split scope deployment does not provide IP address continuity and is unusable in scenarios where the scope is already running at high utilization of
    address space, which is very common with Internet Protocol version 4 (IPv4).

  • Multiple Sites - Single domain - Server 2008r2

    Hi,
    I have six (6) sites all connected to a Head Office site by a high speed VPN.  Currently all use different domain names on their local servers but with new hardware coming i would like to have all sites share the one single domain name for simplicity.
    Head Office has two (2) AD Servers configured handling DNS, DHCP (split scope) etc, both are GC's for redundancy.
    For the branches i was considering setting these up as Secondary AD servers with the Head Office domain and as GC's too.  Each branch server will have their own DHCP scope for their networks and DNS forwarded to Head Office AD servers. Each branch server
    will also be used for file and printer sharing.
    I need to make sure local users to the branch servers authenticate on their own AD server and not hit Head Office which would slow down the process a little.
    Is the above the correct way to do this? 
    Cheers.

    Sounds like you want to configure a Hub and Spoke model, with the Spokes being the branch offices.  This is a good topology.  By default when a branch office is configured the DC for that spoke (Defined by the subnets in that physical site) the
    dcLocator process on each client will default to the local DC unless there are problems that force the client to reach out.  As far as forwarding there is no such thing from a DC perspective but there is from a DNS perspective.
    So after you build out your new domain just make sure you follow the best practice for Sites and Serviecs and you should be good to go.
