WHOA, that's some weird setup.
Everything should work fine on auto/auto. If not both sides of the link need to at least match, or you will get duplex mismatches which will cause a lot of problems

This is our standard at the moment
Switch ---------Phone Switch Port---------Phone PC Port------- PC NIC
Auto/Full Auto/Auto 100/Full 100/Full
There is a long convoluted history behind these settings but we have not had any issues until recently.

When you hardcoded to 100/Full, did you hardcode on the switch end and inside the phone?

Has anyone run across the following scenario -
When large amounts of data are transferred between an IP Phone and an attached PC such as during a Microsoft Office update the update fails. When the failure occurs the phone shows the status of port 2 (PC Port) as no link. it was working fine prior to the update starting. This fails consistently when the phone PC port and the PC NIC is set for 100/full, always seems to work when both are set to Auto/Auto or when the phone is bypassed and the PC is plugged directly into the switch port.
Tried multiple phones 7941/61/11s. Current phone under test is running phone load is 41.8-3-3SR2S and we are connected to a 3750 running 12.2.25 SEE2. Going to do more testing but wondering if any one else may have run across this.
Thanks
Steve
