Why I am getting “Logon failure: user account restriction” while trying to access other Windows XP SP2 computers?
When I am trying to access other computer via the following ways.
Start > Run (Windows Key + R)
- \\ServerName
- \\ServerName\ShareName
- \\ComputerName\ShareName
- \\192.168.123.123\ShareName
It’s giving the following error
---------------------------
Windows Explorer
---------------------------
\\server is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions.
Logon failure: user account restriction. Possible reasons are blank passwords not allowed, logon hour restrictions, or a policy restriction has been enforced.

OK

Solution :
- Start > Run > type regedit.exe and press enter
- Then go to HKLM\System\CurrentControlSet\Control\Lsa\limitblankpassworduse
- change from 1 to 0
Note : Do not use search in windows registry - it will have many entries. Its faster if you go to the required key manually.
