First, find out the address of the Key Management Server (KMS) using DNS replacing the example ".domain.com" with the proper domain for your workstation and environment.
I am using "dig" instead of "nslookup" because it is what I am most familiar with. If using "nslookup" go into interactive mode and change the query type to SRV before searching.
c:\>dig SRV _vlmcs._tcp.domain.com
For example, if your Company Domain is "acme.com", the command would be:
c:\>dig SRV _vlmcs._tcp.acme.com
Next, change to the MS Office 2010 directory. On Windows 7 x64 it is:
c:\>cd "\program files (x86)\Microsoft Office\Office14"
Office 2013 may be in directory Office15:
c:\>cd "\program files (x86)\Microsoft Office\Office15"
Display the current activation status
cscript ospp.vbs /dstatus
Next, set the default server to be used where "lic_server.domain.com" is the one discovered using the DNS lookup above.
cscript ospp.vbs /sethst:lic_server.domain.com
For example, if your company domain is "acme.com" and the license server hostname is "mslicenseserver01" the command should be:
cscript ospp.vbs /sethst:mslicenseserver01.acme.com
Activate Office
cscript ospp.vbs /act
