SYMPTOMS
When the Windows Management Instrumentation (WMI) service starts on a Microsoft Windows Server 2003-based domain controller, the computer may experience high CPU usage. For example, if you press CTRL+ALT+DELETE, click Task Manager, and then click the Performance tab, you may notice CPU usage of 70 to 80 percent. When you click the Processes tab, you may notice multiple instances of the Wmiprvse.exe process. The number of multiple instances of the Wmiprvse.exe process may be more than 100.

The following event may be recorded in Event Viewer:

Event ID: 7023

Description:

Could not start DHCP, not enough storage is available to complete this operation.

Additionally, if you try to add a printer, you may receive the following error message:

Not enough memory to complete the operation.



CAUSE
This issue may occur when the following conditions are true:
 * A UNIX or Linux computer that is running the Samba program is on your network. The Samba program emulates a Microsoft Windows NT Server.
 * The UNIX or Linux computer that is running the Samba program is configured with the same domain name as the Windows Server 2003-based domain controller.



RESOLUTION
To resolve this issue, rename the UNIX or Linux computer that is running the Samba program. Use a new name that is different from the name that is configured on the Windows Server 2003-based domain controller.



MORE INFORMATION
Samba is a third-party implementation of the server message block (SMB) networking protocol that is used by Windows NT.
