Try using this instead:

net use \\(computer name here) /u:(remote user name here)

Then open the network again.

belive me this thing i also developed once myself but...i changed this becoz its an security flaw too

better thing is you use the tricks we uses to increase out internet speed ;-) that doesnt increase internet speed but the LAN browsing of PCs

I changed value of key restrictanonymous to 0 and it worked

I had previously also used Windows Resource Kit Tools. Download, install and then run. Copy and paste the following into the cmd shell
net user guest /active:yes
ntrights +r SeNetworkLogonRight -u Guest
ntrights -r SeDenyNetworkLogonRight -u Guest

Good luck

im using windows 7 and my guest account doesn't have access to the internet, it says in the network and sharing center that it is "unknown" "access is denied", but the internet works perfectly on the admin account.
Thanks in advance.

i have same problem but i can share printer and some files between my desktop and labtop but some files i cant and it says Network acces denied

i hope u can help me

Have been looking all over the internet for a solution. Though I'd rather uncheck some options that were supposed to be unchecked, this works for me too.

To anyone saying their key value already was 0 and that this didn't work: try the computer you want to enter.

Thanks! This solution worked for me!

The registry change to the restrictanonymous key worked well and solved a problem between and Windows7 and XP computer.
Thanks for this.

Leave it to microsoft to screw up network communications that has worked for over 15 years. Win 7 (Home Edition and perhaps other versions) allow you to
map and access WIN XP PC hard drives and folders but not vice versa. When you try to access a Win 7 PC root drive or folder you get the message "access
denied". I have seen a number of so called fixes for this problem on this site and others, but NONE OF THEM WORKED! Many of these fixes involve changes
to the WIN 7 PC's registry that have nothing to do with the problem. I spent about 6 hours to figure out the fix for this problem. I posted a simple tutorial on U TUBE at that will show you exactly how to fix this problem in less than 20 mouse clicks....Kim

That was the answer. I should note that this works with individual folders, which is what I needed.

Hey, man...thank you very much for helping me...God bless you

See you

I have No1 & No2 PC's (XP-Pro) etherneted & one netbook (Win-7 Starter) wifi'd to a modem/router.....all communicating with each other but denied access/file sharing to No1 PC, although oddly the printer could be accessed from No2 PC only.

Now all fully sharing thanks to the 'restrictanonymous' hack.

Thanks a million-billion-zillion to whoever it may concern :-)


thank you, thank you,thank you......... been trying for friggin months to fix this $#@%&* problem. Your the man!!!!!!!!

IT WORKED!!! I've been messing around for hours over years trying to get this particular machine to communicate with just about anything.

MICROSOFT -- question what's the point of a network connection that doesn't allow you to connect to anything?? I shouldn't have to spend half my life tying to get the network to do what it's supposed to do. If there are people out there that want Fort Knox Security then make it so that they spend hours figuring out how to turn it on. The rest of us (I expect) would like just to plug the machine in and share! ARE YOU LISTENING You fascist b***!

MegaLeecher you deserve an OBE. Thanks a million times!

Key already set to zero, but W8 has access denied to this XP. XP can access freely W8. Note, I am not using a Home Network, but a plain Microsoft netework through a router. Help needed!
