When streaming a Windows machine the Windows license can be managed by a Key Management System (KMS). Citrix describes it as follows “KMS volume licensing utilizes a centralized activation server that runs in the datacenter, and servers as a local activation point (opposed to having each system activate with Microsoft over the internet).”
To ensure KMS is working correctly the Windows machine needs to be prepared for KMS, this involves setting the right license key and “re-arming” the license. Citrix has done a pretty good job describing different scenarios in CTX128276 and explaining which actions to take, but there are more steps involved.
In this article I’ll explain what steps you can take to build a PVS vDisk where licensed are managed by KMS and how to troubleshoot some known caveats.
