Planning and Managing Client Licensing and Activation 53
3. If the client succeeds in reaching the KMS host, the activation will be renewed.
a. Once the client is activated, the seven-day counter will be reset on the KMS client.
b. The 180-day counter for the KMS client activation is renewed.
c. The KMS host creates a new record for this client for the activation count (which
is kept for 30 days). The original record is deleted.
4. Seven days after the client is temporarily activated, the process starts again.
Working with KMS
In order for the KMS to respond to activation requests, the firewall needs to be properly con-
figured on the KMS server. If the Windows firewall is being used, the KMS Traffic exception
can be enabled. If a third-party firewall is being used, you’ll need to open port 1688.
In addition, you can use the Software Licensing Management Tool (
slmgr.vbs) to con-
figure and manage specific settings on the KMS server. Table 1.3 shows some of the common
switches used with KMS.
TABLE 1.3 Slmgr switches used with KMS
Switch Description
/sprt #### Use this switch to change the default port number if necessary. The
default port number is 1688.
/cdns This will disable automatic DNS publishing by a KMS host. The SRV
records must be manually created on DNS.
/cpri This will reduce the priority of host processes. Use this if the KMS host
needs more processing power for other server roles.
/spri This returns the priority of host processes to normal on the KMS server.
/sai # You can use this to change how often a KMS client tries to connect to
a KMS if activation fails. The number is provided in minutes, and the
default is 120 (two hours).
/sri # This will change how often a KMS client contacts the KMS host to renew
the activation. The number is provided in minutes, and the default is
10080 (seven days).
/dli When executed on the KMS server, this provides the current activation
count on the KMS server.
/skms You can use this to set the name and the port of the KMS server for non-
domain computers.
