Homegroup and file sharing stopped working over home network

[cluelessjedi]

3 days ago, access through my laptop on my home network to my main pc suddenly stopped working. i installed and changed nothing, as a result i wiped both the laptop and pc and reinstalled Win 7 Enterprise and Win 7 Ultimate respectively and i am still getting the " you do not have permission to access ---" i have taken ownershp, turned off password enabled sharing etc to fix this and nothing has worked. the only clue i have is that it may actually be an issue with the shared drive (storage) as viewing the shared drive over the network, the properties of the drive show up as 0 bytes/files.

Has anyone encountered this before?

Thanks

Can't map a network drive on Windows 7 (it used to work) error: 0x80070035 "network path not found"

Following their first line of questions there. My first question would have to be regarding system security on these two pc's.

Sorry, yes when the problem occurred they were both running Avast free. Although since i have wiped and reloaded both, they have no AV on them at all
