I have a 2008r2 Foundation server that I need to do a 2 way Trust to another domain. The os has informed me that this function is not allowed under Win2008r2 Foundation.
So now I have to do an inplace upgrade to 2008r2 Standard using:
DISM /online /Set-Edition:<edition ID> /ProductKey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
I have since found out that DISM does not work on a AD DC. So now what do I do. If I demote the DC dont I loose all my AD and Settings and Why would you have a Member DC on a 10 User network to move FSMO roles to.
So in My situation is an InPlace upgrade even an option? If it is How. It is a full production network so I cant be down for days rebuilding.
