Hi,
I have broken Labs when installing service packs on exchange 2010 servers because the powershell execution policies have been incorrectly configured. Once the WMI service has been stopped, the scripts within the SP haven't been able to start it up again.
I can't find any info on Powershell script execution policies in relation to the SP3 for 2010 prerequisites. Does anyone know what they should be set at? And why haven't these been at the top of the list of prerequisites for installations of service packs for exchange?
