Sharing error - Not enough server storage to process command" ???

Adding another computer on home network. Have NetBIOS protocol on each
winxp-pro computer. Tried Simple File Sharing which did not work with new
computer so tried unchecking it and having Everyone with full access on new
computer. This did not work also. In trying to map new computer c-drive (set
up to share) error message is "Not enough server storage to process
command". What does this mean???

I do not have a server and am using a Linksys wireless/cable router for
network connections.

Any other suggestions in getting this new computer on network?
