Windows Server Update Service (WSUS) and Windows Activation Service (KMS) of Region eu-nl will be migrated to new servers on February 3rd, 2025

Migration Information

New Servers of Windows Server Update Service (WSUS) and Windows Activation Service (KMS) in Region eu-nl have been set up to support latest MS features and products e.g. Windows Server 2025. These servers have new IP addresses and will be activated by changing the DNS entries on February 3rd, 2025.

If the DNS names below are used, the Windows servers will use the new servers automatically.

WSUS and KMS clients must be reconfigured manually, if IP addresses or different DNS names are used.

Please check the connection to new IPs and verify your security group and firewall rules as well (see https://imagefactory.otc.t-systems.com/home/public-services-in-otc-new-ip-addresses).
