Sometimes it is required to activate the Office 2010 KMS host in a disconnected environment. Here are the steps required to activate Office 2010 KMS via the phone.

*NOTE* If you don’t already have Office 2010 KMS installed please install it as described in the following blog post:
Office 2010 KMS installation and troubleshooting

After installing the Office 2010 KMS host pack from here, and entering your product key, you should get an error during activation if you are not connected to the internet.

Open a command prompt and change the directory to c:windowssystem32.
Type in “cscript slmgr.vbs /dlvbfe7a195-4f8f-4f0b-a622-cf13c7d16864” and hit enter.

You will see your Office 2010 KMS server all of the license files that have been installed on your KMS server.

Copy the activation ID, and the installation ID into a notepad file.
I would then recommend that you put dashes after every 6 characters in the installation ID. like so:

020362-296235-955944-683420-831782-083181-398723-978944-769744

If you are in the USA, you can then dial phone # 888-725-1047 to input your installation ID.
If you are NOT in the USA, at a command prompt type “c:windowssystem32slui.exe 4”. Then choose your country to get the phone #. After you get your phone # from this screen, Close the windows activation window, as we ONLY wanted the phone #.

After you give the automated voice your installation ID, it will return with a confirmation ID.

For example my confirmation ID might be

XXXXXX-XXXXXX-XXXXXX-XXXXXX-XXXXXX-XXXXXX-XXXXXX

Remove the dashes from your confirmation ID:

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

Then to activate use the following command under C:Windowssystem32:

cscript slmgr.vbs /atp XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX bfe7a195-4f8f-4f0b-a622-cf13c7d16864
