Cisco 1121-8PLTE+ DHCP Issue

[parkerparrett]

Hello all,

I have a 1121-8PLTE+ that I am having issues having a Windows 10 computer pulling an address from. I have tried to pull an IP from my MacBook and a Linux device and they both pull an IP address with no problem. The error I get when I try and renew an address on my Windows PC is "An error occurred while renewing interface Ethernet 8: The parameter is incorrect." Any suggestion's would be great! I have attached screen shots of my configs and debug messages some may look weird because MAC's and IP's were redacted.

FIX: Windows 10/11 is unable to get DHCP (IP) address (windowsreport.com)

I dont think it Router issue, 
check how solve DHCP issue in Win10/11

I think the FW deny the dhcp packet

Turns out that it was a configuration issue, I do not have a lot of experience running DHCP pools on the router itself (Usually helpers pointing to a DHCP server) and accidentally put a subnet mask after the default router command which was causing my issue.
