Dhcp not showing address leases

techgeek644 · 2018-09-20T00:56:09.000Z

Hello,

I have created a new scope in my dhcp server. Followed the below steps:

a. created a new scope with IP range
b. given dns, router and domain IP in the advance section
c. activated the scope

Referred the existing one of the other dhcp scope exists in the domain. This scope has been created for wireless devices address lease.

But unfortunately in the address lease section, I could not get any devices details which has got the ip range from the above newly setup subnet.

Please help me with your suggestions.

Restart dhcp server n still doesnt wrk exp dhcp config n reinstall it.

We may use the following steps to export DHCP configurations and import the configurations after reinstalling the role:

step1:Dump the configuration file use command “netsh dhcp server scopeID dump >filename.txt ”

step2: Remove DHCP role and reinstall it.

step3: Import the configurations use command “netsh exec C :**filename.txt**”

step4: Restart DHCP server

Are there any devices connected to the DHCP server in the first place ? Are the devices still laving leases to the previous DHCP server (especially if you set the lease to 1 day or “default” 7 days ? Machines will not change IP address just because you disable or create a 2nd DHCP server.

Yes, there are device connected to the dhcp server. there is only one dhcp server. basically i have two wifi networks in my place. closed and open. where closed dhcp scope able to collect the devices ip address from the leases pool, whereas the open scope does not showing any ip address.

I have only one active DHCP server, need to go through approvals for reinstalling the role, service restart may not be an issue.

Will try If I could able to do that. Thanks.
