That's strange that usually fixes the duplicate IP problem
How about putting the DHCP server on the router instead?
what do you get when you do a "show ip dhcp conflict" command
also can you share the "show ip dhcp pool" command

Hello,
I see your configuration and i see the next:
no ip dhcp ping packets
I think this is your problem, your dhcp server don´t ping for assignated ips.
If you have a rogue Dhcp server (This isn't the case, bacuse the issue was resolved put the dhcp server in the router) you can configure DHCP snooping.

Hi you most probably need to enter the following command on all access ports on the 3650
"nmsp attachment suppress"
Network Mobility Services Protocol(NMSP) is really used for tracking wireless clients as they connect to different Acess points, but it caused problems with hard wired devices, I suspect this problem has been fixed in later 3650 IOS

Hi Richard,
Thanks for your reply. I tried the command you suggested but it did not help. The issue is still there. Any other recommendation.
Thank You.
Kind Regards

Hi Rohit,
Adding to what Mr. Richard. Do you have windows desktop operating system lower than windows VISTA? If yes then have a look at this URL.

I encounter that same issue at one client and had to use Microsoft DHCP server instead. But they were using windows 7.
HTH.
Regards,
Terence
