network stopped sharing files...

Hello,
I'm wondering if someone can help. Please pardon my not so skilled
knowledge base or perhaps correct terminology to try the explain my issue.
I've heard this from others...whatever updates get downloaded and recently
upgraded internet explorer browser.........messed up my network sharing of
files and folders. I have a desktop with a router, also a laptop with a
wireless card both on the same network. I had it set up before where I can
access documents, pictures, music from each of the other computer. Now, my
desktop maintained that capability as I can see when I go into network places
and view the various folders I've enabled to share from the laptop. However,
my laptop lost this capability, all the files and folders I had set up in the
laptop under network places to view desktop material, is gone.
I've already ran network set up wizard on both computers....disabled windows
firewalls again on both. I've checked the enable file sharing sections for
each section I want to share such as documents, pictures, and music. I still
can't access it from the laptop.
Sorry about the long explanation, I hope its comprehensible enough for
someone to be able to please tell me what else I could do. I really hate
those updates and upgrades because they do mess with already existing
settings.
Please help!

Thanks very much,

Jade
