At my wits end with my home network here. I have two Win 7 64bit computers, one Home Premium the other Professional, and seemingly at random when trying to access one or the other over the network it will ask for a username/password. Sometimes it won't ask for one at all, and I'll be able to see shares without problem, but I can't replicate when this does/doesn't happen. I've read as many threads as I can find on this and other forums, but still no luck.
I have no 3rd party firewall and I've disabled Windows Firewall on both computers.
I've disabled anti virus software (MSE only) on both computers.
In advanced sharing, I've turned password protected sharing off (as well as tried almost every other combination of settings on this page)
I've verified that both computers are in the same workgroup, and I am NOT using homegroup sharing.
I've tried uninstalling/reinstalling drivers
for each network adapter.
I've tried disabling IPv6
I've tried looking through the event viewer for any errors.
I've tried 3 different routers
Help! Thank you!
