How do I view Address Leases on 2012 R2 DHCP server with red cross next to Address Leases ?

Posted on 2014-08-11

I have a DHCP server running on my DC. The DHCP information was imported from a 2003 R2 server which is no longer available.

The DHCP server is still giving out leases with no problems. However, I cannot view this information on the DHCP GUI on the server.

Could anyone please let me know if there is a way to rectify this problem ?

    You mention a red cross.

    Looks like a known issue. Here is a thread on 2003 to 2008 migration,

    And the MS link it references

    You might have reservations outside the scope. That's not allowed any more:

    Thanks Carol,

    The reservations were outside the scope and so I removed them. I unauthorised the server and then reauthorised but the red cross remains. I restarted the service but same result.

    The MS article (962335) relates to how to export the DHCP database from the original server but this server is no longer available so unfortunately this is no longer an option.

    In the social technet article the only possible procedure appears to be ..

    1)deleted the scope
    2)unauthorised the server
    3)restarted the service
    4)reauthorised the server
    5)recreated the scope

    Would you recommend this and is there a danger it would cause users disruption ?

    Accepted Solution

    Make sure the DHCP lease is long before you start and choose a time when there are not a lot of computers restarting. While the computer is running it will not contact the DHCP server unless the lease is half way to expiry.
    But it always checks when it starts.
