KMS Server 的Current Count只有10

問題描述:在您的環境下,KMS Client的機器有很多,但在KMS Server上看到的目前計數(Current Count)只有10或是更少,沒有再增加。


1.如果您的KMS Client有Windows 7、Windows Vista等作業系統,但機器的總數量遠超過目前計數的值,您需要注意到當初在佈署這些Client時是否使用同一個Image,如果是的話,是否有做sysprep並且勾上「一般化」,如果沒有做這個動作的話,對於KMS Server而言這些Client的CMID會相同,因此目前計數不會增加。可以參考 文件。

補充說明:如果在這種情況下,即使您在使用同一個Image佈署Windows 7或是Windows Vista,並且做過sysprep和勾選「一般化」的話,目前計數最多只會顯示到50,這個是By design的行為。


2.如果您的KMS Client只有Windows 2008或是2008R2,沒有Windows 7/Vista的作業系統,這個是一個正常的現象。當您要啟動Windows 2008或是2008 R2的KMS Client時,至少要滿足5台的KMS Client,當Current到達5時,這些2008&R2產品即被啟動成功。而Current Count最多其會記錄它的二倍,即2x5=10,這就解釋為什麼目前您在Server看到的Current Count是10。您可以參考以下的描述:

How to troubleshoot the Key Management Service (KMS)

The count will not increase above 50, no matter how many valid systems exist in the environment. This is because they count is set to cache only 2 times the maximum license policy returned by a KMS client. The maximum policy today is set by the Windows client OS, which requires a count of 25 or higher from the KMS host to activate itself. Therefore, the highest count on the KMS host is 2 x 25, or 50. Note that in environments with only Windows Server KMS clients, the maximum count on the KMS host will be 10, as the threshold for server is 5 (2 x 5, or 10).
