This should be so easy! But it's not working for me and I haven't (so far) worked out why.
I have a domain controller (Server 2012) on which I've set a Group Policy Preference to map a drive letter to a share on the server. Works fine for ordinary client PCs on the LAN. However, on the LAN we also have a second server running Remote Desktop Services under Server 2012. If I connect to a desktop session on that using RDP, the drive is not mapped.
gpresult /r says the policy should run. I've run gpupdate /force on the RDP server.
I've tried using an old-style batch file with a "net use" command, kicked off as a Group Policy logon script, instead of the GP Preference. But that doesn't work either.
Not sure why. Permissions look OK.
Any ideas, please?
