Apply Default User Logon Logo in Windows Server 2008
Where several computers are connected to a domain controller in any medium to large scale organization default company logo needs to be there in order to standardize the convention of the organization. In other words in any company when user logon logo is the default given by Microsoft Windows the organization might look a bit unprofessional. On the other hand if an organization has its own company logo administrators may want to use that on every computer in the premises in order to standardize the convention of the organization. Default logo is situated at %PROGRAMDATA%MicrosoftUser Account Picturesuser.bmp location and administrators need to replace .BMP file in order to make their company logo as a default for the users while logging on. After the file is replaced users can use group policies to enforce Windows to use the customized logo. As an administrator if you want to do so you are required to follow the steps given below:
1.      Logon to Windows server 2008 domain controller with domain account privileges.
2.      Open Group Policy Management Console by going to start menu and going to Administrative Tools.
3.      Create and link a new GPO on the target organizational unit or domain and then edit it by right clicking on it and clicking on Edit option.
4.      On the opened snap-in under Computer Configuration expand Policies > Administrative Templates > Control Panel and click on User Accounts.
5.      From the right pane double-click on Apply the default user logon picture to all users and on the appeared box click on Enabled radio button.
6.      Click on Ok button to close the box and in command prompt type gpupdate /force to update the settings.
