Local drives are not available when using RemoteApp on RDS


we have Windows Server 2008 R2 server configured with Remote Desktop Service role with published application via RemoteApp Manager (RDS, RemoteApp, RD Gateway Manager, RD Session Host Configuration Remote Desktop Service Manager).
Classic RDP session to server working fine, all local resources are accessible drives, ports, printers, etc.

Problem is when users starts application from RDS web (RemoteApp and Desktop Connection) or .rdp file , then the local drives are not accessible.

User PCs and RDS server are in different domains with no trust between them.

Our configuration :
1. RemoteApp manager -> RDP Settings -> Common RDP Settings -> Devices and Resources -> all options are checked
2. RemoteApp manager -> RDP Settings -> Custom RDP Settings ->
authentication level:i:2
3. RD Session host Configuration -> Connections -> RDP-Tcp -> Client Settings -> Redirection -> all options are unchecked
4. This is our test environment so no special GPO are applied. Just 4 GPO are applied to server (ntp, wsus, passwod policy, default domain policy), 2 GPO to users (default domain policy, IE trusted)

Thank you for help.

Hmmm, ok, just to make sure, did you run gpresult / rsop.msc on the client machine?

Computer configuration\administrative templates\windows components\Remote desktop services\remote desktop sessions host\device and resource redirection

Should have these two options disabled (default behaviour is on, which over rules the rdp files):
Do not allow clipboard redirection
Do not allow drive redirection

This seems to be inline with the behaviour that it is working for admins but not for users.
Hi Simon, have you checked the settings in the .rdp file on a non working client to see if they are correct? It sounds to me that the settings in the .rdp file are not correct (connect drives disabled).

Hi DrAtomic, we have checked the rdp settings in .rdp file couple of times but didn't find any problems.

I have attached rdp files for IE and excel, please check it if there is some issue.


thank you
Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

Have you tried to republish the rdp file without signing? Alternatively try to edit one of the .rdp files and remove it manually (Find the line starting “signscope:s:” and delete any of the text on that line and after it.)
Also I see that you don't have devicestoredirect set, try setting that to * as well even though that shouldnt be the issue it may be worth the attempt.

Both .rdp files edited :


Everything on the line where signscope:s: is and after it deleted.

Result is the same, local drives still not available.
The idea I was following through here is that local drives not being mapped is the default behaviour, thus it may have had the wrong signscope.

Did you check Redirectdrives in Custom RDP settings; redirectdrives:i:1, see https://technet.microsoft.com/en-us/library/ff393706(v=ws.10).aspx

Hi DrAtomic,
as you can see from attached files before, the redirectdrives:i:1 has been set.

Maybe there is discrepancy between rdp settings in .rdp file or we are missing some setting.
Do you have any idea what else we can check?

Thank you.
Hmmm, I'm running out of ideas here, just to make sure, is the RDS server domain added to the IE Trusted domains in the policy on the Users domain?

Did you check the eventlogs (both client and server sided) to see if that contains any hints?
ZUNOAuthor Commented:
RDS server domain is added to the IE Trusted domains.
No problems/errors in event log, just common information.
