Existing tools that ran correctly on Windows 2000 might fail on Windows 2003 Server. This means that a tool set up to run as a domain user will fail with the following error message:
Logon attempt for user (ov-excl\joec) failed. The account
name may be unknown or the password was wrong.
Go to Start Administrative Tools Local Security Policy. Then select Local Policies User Right Assignment and right-click Allow log on locally to open the properties of the Allow log on locally setting.
