Very interesting issue on this to which i am still trying to isolate why it happens.

i rebuilt 15 servers in lab today and decided to script the enablement of hyper-v with start /w ocsetup Microsoft-Hyper-V

i got the prompt to reboot and then off it went installing hyper-v

I went looking for the hyper-v manager icon to import some VM’s but i could not find it!!

i went into server manager and it said the role was not installed … starting to get confused here

so i decided to uninstall hyper-v using the command line…

start /w ocsetup Microsoft-Hyper-V uninstall

reboot the servers as part of the process and re add it with the server manager gui….

and hey presto all better Smile

strange one…..
