Disable/Modify Loopback check:

Other things to check:

IE - http://localhost is trusted
IIS - virtualdir/configuration/debugging/ enable asp server-side script debugging
NTFS - physicaldir/security/ - make sure your user account has full permissions
IE7 - internet options/security settings/local intranet/custom level - bottom make sure "automatic logon with current user name and password" is checked also add http://localhost to the sites list
NTFS - inetpub\wwwroot\ - give your account full control
Local Users and Groups - make sure you are indeed a member of debugger users; also add aspnet account to debugger users group
Web.config -
C:\WINDOWS\Microsoft.NET\Framework\\ - ensure ASPNET Machine Account has full rights
CMD - C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\aspnet_regiis.exe -i

Ubuntu Recovery

Got locked out of Ubutu login screens. To recover, hit escape at the beginning of the boot cycle to get a menu of boot options. Boot to recovery mode. In recovery mode, add a user by adduser [username]. then follow this post:

#addgroup –system admin
#visudo The sudoers file should then be edited to include:
%admin ALL=(ALL) ALL
#adduser username admin

in my case, the admin group already existed. so i skipped ahead to adduser [user] admin
