Hi all. We've had a whole bunch of PC problems lately and it all pointed to the phone.
During the phone deployment stage, we've decided to hard code the LAN and PC port to 100/full, and PC NIC to 100/full.
PC port on the phone was showing as half duplex when you choose "Display" settings, but when you choose "Modify" and scroll through, it was showing as Auto/Auto. Seting it to 100 full got the PC working again.
Has anybody seen this before? What can cause a phone to change its' settings without manual intervention?
