No active Leases in Windows DHCP gui , but when check over Command Shell there are active Leases
Hello , We want to Monitor active Leases in DHCP with CheckMK. It works so far . We create an own Scope . In this Scope there are two IP Adresses . When an Server becomes one of this both IP Adresses the we become an active Lease . This Lease brings the Monitoring Software to an Alarm . We setup an Leasetime for this Lease under the Scope Settings to 5 minutes. The Target should be that the Monitoring Software brings an Alarm when one of this two Leases or both are aktive. But we want to become back an green ( good ) Monitoring Message , when the Server who becomes the IP Address is shut down and the Lease Time from 5 Minutes are gone . Means then there are no active Leases at all . But now our Problem . We shut down the Server and after 5 Minutes aktive leases under DHCP Server was empty . BUT When i put in this command : “netsh dhcp server show mibinfo” then i become back this info : C:>netsh dhcp server show mibinfo MIBCounts: Discovers = 5167. Offers = 5167. Delayed Offers = 0. Requests = 246250. Acks = 246422. Naks = 7. Declines = 0. Releases = 63. ServerStartTime = Freitag, 5. Juli 2024 23:00:21 Scopes = 24. Scopes with Delay configured= 0. Subnet = x.x.x.x. No. of Addresses in use = 1. No. of free Addresses = 1. No. of pending offers = 0. Means the System think that there is already an active IP but the GUI dont show it . How is it possible to bring back the No. of Addresses in use back to zero ? Thanks Michael
IPAM issues with DHCP in Windows Server 2016
Hello everyone. My name is Chris. I'm a student at Georgian College and I'm trying to resolve an issue with Windows Server 2016 and IPAM in one of my labs. I am in the IPAM > Server Inventory > IPv4 screen and have configured my manageability status to "Managed" and have toggled on DC, DNS and DHCP server options (as per the lab instructions). However, I keep getting a red x when I have DHCP toggled on. If it is toggled off, then I can get the green check mark in the IPAM access menu. I am unsure of how to troubleshoot this issue and I am frustratingly close to getting the lab done. I haven't been able to find any information online as to what the problem is, and am wondering if you know what is happening. Thank you for your time, and have a good day.
