SYMPTOMS
You try to activate a new Windows Vista-based client computer. If the client computer is hosted by a computer that is running the Key Management Service (KMS), the client computer may not be activated successfully. Therefore, the computer is not added to the KMS pool. Instead, you receive the following error message:

0xC004F038

The computer could not be activated. The returned count from your Key Management Service is insufficient.



CAUSE
This problem may occur when there are fewer than 25 client computers in the KMS pool.



RESOLUTION
To resolve this problem, you must add more client computers to the KMS pool.

To determine how many computers are in the KMS pool on the KMS host, type the following command at a command prompt, and then press ENTER:

Slmgr.vbs -dli
