issues with sharing documents folder

I have 2 vista machines one w/biz and one w/hm premium. I had been able to
share 1 or 2 files on the hm machine and the biz machine could see those
files but when I try to share the whole documents folder on the vista hm
machine it goes thru the motion of setting the share but the little icon
indicating it's shared isn't present nor can I see the shared documents
folder. I can share sucessfully a printer on the hm machine with the biz
machine sucessfully so it's NOT a permission issue. I think file sharing has
gotten corrupted some how on the hm premuim machine ...

thanks :-)
