Otherwise, each client computer looks identical, and the KMS host does not count them as separate KMS clients. To reset the client computer ID (CMID) and other product-activation information, run sysprep /generalize or slmgr /rearm.
The general syntax for this command is as follows: slui.exe 0x2a ErrorCodeįor example, if event ID 12293 contains error code 0x8007267C, you can display a description of that error by running the following command: slui.exe 0x2a 0x8007267Cįor more information about specific error codes and how to address them, see Resolving common activation error codes. IT pros can run Slui.exe to display a description of most activation-related error codes.
Windows logs KMS events to the Key Management Service log in the Applications and Services folder. Make sure that routers do not block traffic using TCP port 1688 (if the default port is used) and that stateful traffic to the KMS client is allowed.Įxcept for KMS events that have event ID 12290, Windows logs all activation events to the Application event log under the event provider name Microsoft-Windows-Security-SPP.
Until the KMS host has a count of 25, Windows 7 client computers cannot be activated. On the KMS host computer, run Slmgr.vbs and use the /dli command-line option to determine the host’s current count. Verify that the KMS activation threshold is met. The KMS client computer does not activate Alternatively, run Slmgr.vbs and use the the /dli command-line option. On the KMS client computer, open the System control panel, and look for the Windows is activated message. If you use System Center Operations Manager, the System Center Data Warehouse database stores event log data for reporting, therefore you do not have to back up the event logs separately.
If you use the event log to track or document KMS activations, periodically export the Key Management Service event log from the Applications and Services Logs folder of Event Viewer. However, if you use a tool to routinely clean up event logs, the activation history stored in the logs can be lost. Should I back up KMS host information?īackup is not required for KMS hosts.
