Windows Server 2016 installation with 3 Remote Desktop Services (RDS) session hosts servers, one domain controller. There is a user group configured for RDS users with group policies for a few settings.
Logging into one of the RDS session host servers with a domain admin account, changing a file in one of the folders below c:\Program Files. If I now log onto ANOTHER server with the SAME domain admin login, this file has also changed there, on that other server! I haven't touched that server at all!
(I do understand this would happen if I change files related to users, i.e. in the user profile folders under c:\Users\, these are roaming profiles of a sort.)
Does this mean the "c:\Program Files\" is now also included in the user profile ...? That is entirely unexpected and I cannot find any hint or documentation that this should be so.
It is extremely annoying as I do not always intend these changes to be identical. It "could" be useful for a farm of RDS servers, but it is spooky - this "action on a distance".
When I log on with local admin, then the file I changed is unchanged. So it really seems that I the entire C drive has become part of the user profile ...?
Conversely, creating files in a local login in the "c:\Program Files" folder are NOT visible in any domain login, and vice versa.
DFS (Distributed File System) is not configured. Unless it configures itself by default? This is a clean install from scratch.
Steps to reproduce:
log in with a local admin login create a folder "test-local" under c:\Program Files create a text file "test-local.txt" in that folder sign out log in with a domain account (domain admin) look into c:\Program Files - the folder "test-local" is not present create a folder "test-domain" under c:\Program Files create a text file "test-domain.txt" in that folder sign out log back in with the local admin account the folder "test-domain will not be present, you'll see only the "test-local" folder
