I have an issue on Cisco switch 3750x ( 15.0(2)SE2 C3750E-IPBASEK9-M)
suddenly current existing network has its DHCP pool all addresses excluded, created multiple new DHCP pool to test but same result ( screenshots).
Cleared DHCP binding and cache but it did not hand any IP to clear anything, restarted the switch and same result, do I change the image and try or is there a solution for this problem ?

run small lab
dhcp pool mhm
net 10.0.0.0 255.255.255.0
!
ip dhcp excluded-address 10.0.0.0 255.255.255.0 <<<<
and give me the same result excluded all ip
so your issue is the
ip dhcp excluded-address 10.3.9.250 255.255.255.0
ip dhcp excldue-address 10.3.10.99 255.255.255.0
remove this and your issue will solved

may be you misconfig the dhcp exclude ?
can I see the config of DHCP pool ?

check the screenshots, it has the exclusion, the dhcp pools and the show command of the dhpc
the new DHCP i created for testing has no exclusion. and this issue just appeared out of no where during production

i took the same DHCP pool configuration and pasted it on different switch and gave me normal result of excluded addresses 0 unlike the affected switch giving me excluded addresses of 254
