Another internet connection sharing error.
This one is a bit easier, three possible causes:
1) misconfiguration in the ethernet adapter (ethernet card's) configuration in Network in the Control Panel. As a
default, it is highly recommended to not change your ethernet's cards setting in Network in the Control Panel. Many
times this is the cause of this error.. Someone went a tweaking looking for a couple extra percent in speed, and now
there are issues.
2) Ethernet adapter has the wrong drivers... check to make sure you have the correct drivers for the ethernet card..
again hope nobody was updating them.. but sometimes windows update will update them for you.. if need be, possibly roll
back the driver, or pull the driver disk/cd out of the box which you kept from when you both the computer/ethernet
3) Check the Ethernet cable, is it unplugged, damaged, chair roll over it, cat pull it out? Unplug and plug it
back in, both ends, and if possible, change cables. This is by far the most common reason for this error.
