When a Windows server 2008 computer is promoted to domain controller several other services are also installed and initiated and continuously keep on running in the background. This means that the hardware part of the computer utilizes additional resources and memory is among one of the most important resources that it has. Because of regular usage of memory while working with Windows server 2008 it is quite possible that it may get corrupted or completely damaged. To avoid losing data because of such issues administrators may want to go for Memory Diagnostic Check which will check for any damaged information or physical memory. As an administrator if you want to initiate Memory Diagnostic Tool you are required to follow the steps given below:
1. Logon to Windows server 2008 domain controller computer with the account that has domain admin privileges.
2. Click on Start button and from the available menu go to Administrative Tools.
3. From the available list click on Memory Diagnostic Tool.
4. On Windows Memory Diagnostic Tool box click on Restart now and check for problems (recommended) option to start the process.
Note: This process will restart the computer and will diagnose the memory for any errors. The process may take some time and administrators need to wait till the process is complete. In complex network setups administrators are advised to have redundant servers as Memory Diagnostic process may cause some downtime to the server at least for a while.
