users unable to connect to lan thru C4506 anymore.
no network / switchport changes made
switchports set to following:
switchport mode access
vlan 1 is being used as default vlan
can ping dhcp server and rest of network
when users boot PC, they hang until network cable is unplugged. once they've logged in (cached credentials), network cable can be plugged back in and they work fine
issue is with this switch ONLY.....dhcp server shows no errors / events. all other users on other switches connected to same network have NO issues.
IOS: 12.2.18(EW) --- i know.....OLD. dont know if THIS would cause SUDDEN problem.
thx for any info.
