Question : An Extended Error has occurred.  Failed to save local policy database.

I am trying to modify the "Allow Login Locally" local security policy in Local Policy -> User Rights assignement.  When I add in any domain global group, and click OK, I get the error An Extended Error has occurred.  Failed to save local policy database.  The same error happens on any security policy when I try to add a domain global group (I've tried 3 different ones).

The computer I am making this change on is Windows 7 professional.  The domain ADS server is Windows 2000.

As per this link, I have tried the following 2 things:
http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/sag_scetroubletn.mspx?mfr=true

1) I have booted the computer in safe mode (with network) and verified the security database at %windir%\Security\Database\Secedit.sdb via the esentutl /g command.  It checks out OK.

2) I have also searched the file at %systemroot%\security\logs\winlogon.log for 1332.

This problem happens on all 3 Windows 7 professional systems that I have joined to the domain.  All three systems are brand new installs with very little customization, and no other applications yet installed.

I have also checked the security on the Secedit.sdb file.  It looks as I expected with SYSTEM and administrators having full access.

I have tried making the modifications using the domain administrator account, and the local administrator account.

Answer : An Extended Error has occurred.  Failed to save local policy database.

you can set visibility through style

document.getElementById('idofelement').style.display("none"); //hide element
document.getElementById('idofelement').style.display(""); //display element

css display will make the element invisible and also hide it from the page so elements will shift as if the element you hid was gone from the page

document.getElementById('idofelement').style.visibility("hidden"); //hide element
document.getElementById('idofelement').style.visibility("visible"); //display element

css visibility will make the item invisible, but it will still hold it's place on the page

for example if you had 3 images, and you used css display property to hide the middle image, the third image would move to be next to the first image, as if there was no 2nd image there. If you used visibility to hide the middle image, then the middle image would disappear and it would look like there was an empty space the size of the middle picture between pictures 1 and 3
