While in route to San Diego, I got this comment from a customer “Someone told me that Server 2003 requires a logon in order to shut down. Can you confirm?”
You may be having the same problem.
Considering it’s Microsoft, there may be multiple methods to resolve the issue, but here’s one method to correct:
To change the behavior on a single server:
1. Click Start / Run and type gpedit.msc to launch the Group Policy Editor
2. Expand Computer Configuration / Windows Settings / Security Settings / Local Policies / Security Options
3. Select Shutdown: Allow system to be shutdown without having to log on and change the Security Setting to Enabled.
4. When the policy is reapplied, the Shut Down button will be available as shown below:
To enable on multiple servers, use domain group policies.
