How often does my machine need to contact the KMS?
The product will attempt to contact the KMS to renew its activation period every seven days. If unable to connect after seven days, the machine will attempt to contact its KMS every two hours until it is successful. The product needs to communicate with the KMS every 180 days.
What happens on the day 181?
Microsoft Windows will change its status from being licensed to starting a 30-day grace period. After the 30-day period expires, the product will shift to reduced functionality mode.
Can I use a KMS from behind a firewall that uses NAT?
Yes. Communication with the KMS is originated from the client machine.
Can I connect to the KMS from off campus using the TAMU VPN?
Yes. Microsoft has indicated that Microsoft Windows will attempt to connect to its associated KMS server after a VPN has been established, though this has yet to be tested.
I run my department's firewall and need to know what port to allow.
KMS communication occurs on port 1688 using a TCP connection to kms.tamu.edu.
NOTE: Every effort will be made to not change the IP address of the KMS.
I have a stand alone machine that will never be "online" to contact the KMS server. What do I do?
You need Multiple Activation Key (MAK) from the Software Center. One would be needed for Windows, one would be needed for Office. You will need to specify how many uses you will want (for each MAK).
For Windows 7, go to "System Properties" (right click on Computer, select Properties). Under "Windows Activation", choose Change Product Key.
NOTE: If that option is not available, you can do the following from command prompt with Administrative Privileges:
- slmgr.vbs -ipk your_product_key
- slmgr.vbs -ato
For Office 2010, go into Control Panel > Programs > Programs & Features and select the Microsoft Office entry. Right Click and select "Change” and choose the Enter a Product Key option.
