administration - How to get to c$ with Windows 7

I'm trying to get to the admin share on a Windows 7 home machine from a Windows 7 home machine and nothing is working. I enabled file and print sharing in the firewall and even turned Windows Firewall off. I can get to the "Users" share that I remember setting up when I first installed.

When I go to \machinename\c$ instead of \machinename\users I get asked for a username and password and nothing works (not even machinename/adminuser). \users works because I'm using the same username and password on both machines (like in the XP/2000 days).

Is the admin share c$ gone in Windows 7?

Answer

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
add a new DWORD  called LocalAccountTokenFilterPolicy and set it to 1 
reboot. 

Delete it or remove the key when you don't want it anymore. Need i say from a security perspective this is suboptimal?

Filesharing needs to be allowed and the firewall need to be configured to allow that aswell.
