Hello!
We have some trouble with the KMS activation on some of our Office installations. The computers with problems are Windows 7 and they previously had Office 2010 installed (we had used up all the MAK activations, and had to activiate them by telephone... the reason we changed to KMS). KMS activation functions as it should be on the computers that had Office 2013 clean installed.
I've tried the following:
Set the default license key in case it remembered the old 2010 key
Run commands such as slmgr.vbs /skms [servername]:[port] and manually registring said server and port in Registry.
Ping the KMS server (both servername and IP). It replies.
Also tried to uninstall Office 2013, run CCleaner on Registry and reinstall Office 2013 (in case some of the old configuration of Office 2010 still remained in Registry).
Tried to run the troubleshooter for Activation of KMS Clients and it gave the report of 0xC004F056, and said that the TCP request to the KMS host failed. It's report also links to Article 2870357 - Telnet failure, but I've followed that and it did not work.
Does anyone have any idea on what I can try now? Something else than using MAK activation or reinstall the computers with Windows 8 and Office 2013?
Thanks for any help!
