What is the reason, machines are showing limited or no connectvity if DHCP is enabled ? Some machines are working fine on DHCP & easily taken IP through DHCP but some machines creating a problem to pickup the ip address through DHCP on same vlan.

Hi Sachin,
Those machines which are showing limited or no connectivity, are into the right vlan's on their access switch ports and are admin up and are access ports?
Can you also verify if there are any free ip addresses in the address pool?

Checked DHCP Pool, lot of IPs are avialable that time. All machines are in correct vlan & admin up.

OK Thanks for confirming.
Where are the dhcp servers located? is it in same vlan or a different vlan?
Can you also confirm if those machines (those which got an ip from dhcp and those which couldnt get an ip) are connected to the same switch or different switch? If different switch, is dhcp reachable from that switch? are ip helpers configured correctly and is that vlan allowed on trunk?
Can you move the port of machine which is not getting ip address to the port of a machine which gets ip address and see if it gets an ip? If it gets an ip then issue might be in port config.
And also, can you please manually configure a free ip from the pool and see you get a connection?
