We have a number of Windows Server 2008 R2 SP1 servers running on ESXi servers. At year end rollover 2014 to 2015 the CPUs go to 100% and the machines hang.
The solution appears to be a hotfix (KB2800231) from Microsoft. However, the only listed downloads are all for Vista (Windows 6.0) and our servers are 6.1. Needless to say, when trying to run the MSU it errors saying that we have an unsupported operating system.
The hotfix web page (http://support2.microsoft.com/kb/2800213/en-us) indicates that there should be downloads for 2008 R2, but it is not clear.
Does anyone know of a later fix for this problem, or where the correct MSU can be downloaded?
