How to configure Home Folder with extra security

Posted by Saugata

If you are having a domain controller, and decided to give a personal drive for all users, then home folder configuration is the best way to do it.

But if you want to make it secure for every users, then you have to configure something extra with ntfs security and share security.

Our current requirement as follows:

  • Deploy home folder for 500+ users
  • Make it secure, so that one user can not view others home folder from home share. Browse option should be disabled.

First option was easy and simple, but I have to think a lot on second option.

You can get the overview on how ntfs permission works on network share from following:

RealVNC MSI Deployment

Posted by Saugata

vnc

For giving instant remote support to almost 1500+ desktop, we have to use some remote control tool, so we decided to install RealVNC server only to all the system. But manually it will take huge time to install RealVNC server to all the system. So, I started working on convert it into MSI package, which we can easily deploy via Group Policy.

Also we have to keep following things on mind:

  • For security reason, as per company policy, Windows Firewall should be on to all system, So, I we have to make it an exception on firewall exception list.
  • RealVNC server password should be same in all the system.
  • Package size should be small, so it can be easily deploy.

And finally I have created the MSI Installer. This installer will really small in size, only 533 KB and also iwll will add VNC Port and Application into Windows Firewall exception list at the time of installation. It also set a default password.

Posted by Saugata

Whenever you try to run any script, batch file or an executable from UNC path, it's opening a Security Warning. Actually this will prevent you from running any application from network path.

Custom Group Policy(GPO) for Changing Desktop Background Colour

Posted by Saugata

As per requirement, we need to change all client windows (XP, and 2003) desktop BG color, but it's impossible to change BG colour manually over 1000 desktop. So, we have to do it with an automatic process.

First we have to find out what happened on registry, while we changing Desktop BG color, and to do so, we need a tools which take a Windows Registry Snap after and before changing desktop BG color,

RegShot is the best free tools for that,


Download:

  RegShot (89.2 KiB, 322 hits)

So, finally we able to trace out that registry change,

1
2
[HKEY_CURRENT_USER\Control Panel\Colors]
"Background"="26 26 26"

Initially we add an extra line on logon script, to change desktop BG color to black,

1
REG ADD "HKCU\Control Panel\Colors" /v Background /t REG_SZ /d "0 0 0" /f

It works fine on all Windows XP Machine, but not with few Windows 2000 computer, in that case we are searching for some alternative solution,
Now we decided to create a ADM file for custom group policy,  to force BG color change via GPO.

And here we are, with the following adm file we can change BG color to Black, White, Red, Brown, Yellow, Green, Sky, Brown, Blue, Dark Blue, Pink, Grey... :P
