I am a bit late in getting this post up (due to being on the road at TechEd Australia & TechEd New Zealand); but last week we released a hotfix rollup package.

This package includes the fixes for three of the five issues that I recently blogged about.  The specific issues that are addressed are:

KB Number: KB975530
Title:Stop error message on an Intel Xeon 5500 series processor-based computer that is running Windows Server 2008 R2 and that has the Hyper-V role installed: "0x00000101 - CLOCK_WATCHDOG_TIMEOUT"
Description:This is fairly simple.  If you have a computer with an Intel Xeon 5500 series processor or an Intel Core-i series processor and you see this blue screen – install this hotfix.
Extra detail: I blogged about this back in October.  Some of you reported that this did not solve the problem for you.  The hotfix has since been updated to address the problem on these systems that were missed with the original fix.

KB Number: KB981791
Title:"STOP: 0x0000001a" error message on a computer that has an Intel Westmere processor together with the Hyper-V role installed on Windows Server 2008 SP2 or on Windows Server 2008 R2
Description: Once again, if you have this processor (Intel Westmere) and see this blue screen – get this hotfix.

KB Number: KB974909
Title: The network connection of a running Hyper-V virtual machine is lost under heavy outgoing network traffic on a Windows Server 2008 R2-based computer
Description:This affects all guest operating systems.  The fix is applied to the hypervisor and while a reboot is required for installation, no updated need to be applied to the guest operating systems.
