Yep I have exactly the same problem - been working all morning at it!

My wireless from the PC and D-Link ADSL router works fine for both (XP)the PC and Laptop into the net....

Can share files from Laptop to PC ok but like the previous post cannot share from the PC to the Lap top. I get the same message when trying to access files from the laptop. Following 'help' usage I created a 'shared documents' file but that caused all the My Documents to migrate to it and I could not then access My documents from Front Page so I have just copied it all back - leaving my shared documents standing alone.
There must be a better way?
A way to share MY Documents on the PC? (without creating a My Shared documents folder)
Apart from that I cannot get the PC to do what the laptop does which is to allow all my files to be shared?
There has to be a way.... would be grateful for some help

regards

Michael
