Ensure that the server clock is synchronized with the KMS clock. Other hosts cannot modify or update the SRC if the DNS server is not properly configured. The first host computer automatically reveals its existence when it creates an SRV record on the DNS server.

If you are using KMS, the host computer must be discoverable on your local network.

Set permissions to allow updates by members of this new group on the DNS server.

Add each computer running KMS to the newly created global security group.

Create a global security group in the Active Directory service domain.

Make sure that all computers are in the same Active Directory service domain.

Step 1 : Download PC Repair & Optimizer Tool (Windows 10, 8, 7, XP, Vista – Microsoft Gold Certified).

The program fixes common errors that might occur on Windows systems with ease - no need for hours of troubleshooting when you have the perfect solution at your fingertips: Additionally it is a great way to optimize your computer for maximum performance. You can now prevent PC problems by using this tool, such as protecting you against file loss and malware. To avoid this scenario, configure the KMS clients to use Auto Discovery.

If clients are not using Auto Discovery, you must manually update the KMS client computers that have been assigned to the failed KMS host by running slmgr.vbs /skms. When your KMS clients use auto-discovery, they automatically select another KMS host if the original KMS host does not respond to renewal requests. The new KMS host then begins collecting client renewal requests and begins activating clients when the KMS activation threshold is reached.

If the network uses DDNS, the new KMS host automatically creates a new SRV RR on the DNS server. If the new host has a different computer name, you can manually remove the failing host’s DNS SRV-RR or (if scanning is enabled in DNS) have DNS remove it automatically. If you install the new KMS host with the same computer name and IP address as the failed KMS host, the new KMS host can use the failed host’s DNS SRV RR entry. Ensure that the new KMS host has an RR VRS in the DNS database.

If a KMS host fails, you must install a KMS host key on a new host and then activate the host. Update: Stop getting error messages and slow down your system with our optimization tool.

Newly added computers do not increase the number of KMS.

Ensure that the server clock is synchronized with the KMS clock.
