Volume license customers who downloaded and installed the version of Office 2010 Proofing Tools Kit that is dated November 5, 2010 (or an earlier version) may experience an issue when they try to activate Office 2010.
Any customer who installed the Proofing Tools Kit by using the default Config.xml file that was included with the kit sets the KMS host value on their client computers to a KMS host that is internal to Microsoft. This overwrites the value in the Config.xml
file that existed before the Proofing Tools Kit was installed. This new value breaks automatic discovery of KMS hosts for every client on which the Proofing Tools Kit is installed. This issue then prevents Office applications from activating against the KMS
host or hosts that were specified in the Office 2010 Config.xml file beffore the Proofing Tools Kit was installed.
Customers may not be aware of this issue for between 30 and 180 days.
When the client computer tries to contact the incorrect KMS server that is listed in the Config.xml file, the user receives the following error message:
"0x8007232B" = "DNS name not found" or "C004F074" = "No Key Management Service (KMS) host could be contacted"
