PC Port will not pass DHCP when connected to Cisco Switch
I have a client with a Cisco ESW 520 24-Port switch. It was left at his new location when he moved in about 8 months ago. He plugged everything in and everything worked. So I didn't think there was anything unique programmed in the switch, so I did a hard reset to get access to it. After that, the PC Port on all of our T20 phones stopped working. It appears the phone gets a DHCP address but the PC attached to the PC port cannot get a DHCP address. If I put a static IP on the phone, the PC port doesn't work either.

I have tried everything I can think of. I know Cisco switches can be a little different than others. I have a feeling it may be a VLAN issue, but I don't have any VLANs other than the default VLAN configures.

HELP!

Thanks in advance!
