8.1's time on my laptop was also short lived. It appears that the retarded networking in Windows 8.1 has been nothing but a complete pain in the ass for access shared drives & printers on a wireless network. I'm using 5 different laptops all running different versions of windows (two XP, two 7, one vista), and every one of them can access the shared printer & drive by giving login credentials of the administrator account and voila. This piece of #$%# doesn't even give me that, but rather keeps throwing error after error about not having sufficient access privileges, despite the fact that I've granted "Everyone" full access control on the drive as long as they provide username/password.
I've wasted nearly 2 nights trying to figure out just wtf is up with it. I've tried;
1. Disabling firewall
2. Disabling Guest account
3. Disabling Password Protected Sharing
4. Tried every other network related setting on Microsoft answers
None of them have worked. I've tried accessing directly via IP address as well, that didn't work either. I can ping the ip address just fine, but access is denied regardless of any setting I've done on the main PC where the drive is shared.
Microsoft manages to fook up networking aspects upon every new windows release, but this one takes the cake. They should take a cue from how their competitors do it. Networking on both Ubuntu & Mac is a breeze compared to this abomination.
