/Update End

 

 

Recently we published a Rollup Fix for System Center Virtual Machine Manager 2008 R2, and an Update for the Management Console on Microsoft Update.

When you remove a virtual hard disk from a virtual machine in System Center Virtual Machine Manager 2008 R2, the .vhd file on the Hyper-V server is deleted without warning

http://support.microsoft.com/kb/976246

 

 

 

When your SCVMM Server or Admin Client is not directly connected to the Internet you may have the need to download the package from another machine

You can get the fixes from http://catalog.update.microsoft.com and specifying Article 976244 and/or 976246.

You’ll get .cab files containing .msp files which you can install from an elevated Command Prompt.

 

To install the Server rollup specify:

msiexec /p vmmServer64update.msp BOOTSTRAPPED=1

 

To install the Client rollup specify:

msiexec /update vmmClient64Update.mspBOOTSTRAPPED=1

or, if your Admin Machine is 32bit:

msiexec /update vmmClient32Update.mspBOOTSTRAPPED=1

 

Cheers
