Windows 7/Windows Server 2008 R2/SBS 2011 RTM or SP1 – Slow System Startup and Login

You may experience very slow system start up on occasion, this is due to Windows carrying out an unnecessary validation of the WMI repository.  This validation is very time consuming and slows the overall start up and login process down.

A Microsoft hotfix is now available KB 2617858 http://support.microsoft.com/kb/2617858 and should resolve the slow startup by preventing unnecessary validations of the WMI repository.


You may find that the DHCP Server Service Crashes in Windows Server 2008 R2 and SBS 2011 – RTM or Service Pack 1

If your Windows Server 2008 R2/SBS 2011 system is running the DHCP Server service then you may find that it crashes randomly, this is due to a race condition in the service.  If you do not have the service recovery option set then the DHCP Server service will be unable to service client DHCP reqests until you manually restart the service.

Microsoft have posted a hotfix for this issue and explain the issue in more detail here http://support.microsoft.com/kb/2616864

KB 2616864 provides an updated version of “Dhcpssvc.dll” to prevent the race condition and potential crash.
