Determining Which Activation Method Office is Using – KMS or MAK

Click the start menu and enter cmd /k cscript “%programfiles%\Microsoft Office\Office14\ospp.vbs” /dstatus in the search box.

If 32 bit on 64 bit , %programfiles% above should be replaced with %programfiles(x86)%.

Not Activated


Checking if a Domain is Configured for KMS Auto-Discovery

To check if a DNS domain is configured for KMS auto-discovery, check that a SRV record exists.

nslookup -type=srv _vlmcs._tcp.

If a SRV record exists for the domain, the DNS server will detail the SRV record.

C:\>nslookup -type=srv _vlmcs._tcp

Server:  ward-dc02.wardvissers.local


Non-authoritative answer:

_vlmcs._tcp.wardvissers.local SRV service location:

          priority       = 0

          weight         = 0

          port           = 1688

          svr hostname   = ward-dc2.wardvissers.local

If no SRV record exists for the domain, the DNS server will return an error

Verifying that a Windows Computer can Communicate with the KMS Activation Server

KMS activation requires that the machine to be activated has TCP port 1688 open for outbound communication to the activation server.

Verifying that outbound TCP port 1688 is open to the KMS server

  1. Download and install the utility portqry.exe from Microsoft. It is a command line utility from Microsoft that reports the port status of a remote host.
  2. From a command prompt, run the command:

portqry.exe -n ward-dc02.wardvissers.local -p tcp -e 1688

The command will return “TCP port 1688 (unknown service): LISTENING” if the computer is able to communicate with the KMS server.


If the command returns “TCP port 1688 (unknown service): FILTERED” then the computer is unable to communicate with the KMS server

Manually Specifying the KMS Activation Server

1. Type cmd in the search bar to locate the command window..
. At the command prompt, type cd\Program Files\Microsoft Office\Office14.

If running 32 bit Office 2010 on 64 bit Windows, Program Files above should be replaced with Program Files (x86).
Run the command cscript ospp.vbs /sethst:ward-dc02.wardvissers.local to manually specify the KMS activation server.

Run the command cscript ospp.vbs /act to activate Office with the KMS server.
