using RegistryKey.OpenRemoteBaseKey Method properly C#

Summary:

I need to use RegistryKey.OpenRemoteBaseKey to query remote registry of HKEY_USERS

Full Explain:

I am currently trying to query registries on remote machines. My code of the RegistryKey.OpenRemoteBaseKey Method is below. I know that the "environmentKey = RegistryKey.OpenRemoteBaseKey(RegistryHive.CurrentUser, remoteName).OpenSubKey("Environment");" line from the original example at registrykey.openremotebasekey works. However, i need to query HKEY_USERS which would change the statement to RegistryKey environmentKey = RegistryKey.OpenRemoteBaseKey(RegistryHive.Users, remoteName); and this line does not work.

Any help or code samples would be greatly appreciated! I just need to query the HKEY_USERS registry entries on a remote system. Any method will work for me, my code below is only because its the best method i have found so far to get what i want/need. I am open to change :)
