Summary
This article describes how to map drives in an RDP pass-through session within an ICA session.
Background
When opening an ICA session inside an RDP session, drive mapping works differently than ICA pass-through or drive mapping in a single session.
The procedure below describes an RDP session launching an ICA session to another server:
1. Launch an RDP session from the workstation to Server 1.
2. From Server 1, launch an ICA session to Server 2.
Resolution
There are two scenarios:
• Mapping local workstation drives in an ICA session launched from Server 1 to Server 2: In this case, drive letters are not assigned to the client drives mapped in the RDP session. Thus, the ICA session cannot in turn map the drives.
Workaround: Assign letters to this drives manually by using a script in the logon process or issuing the following commands:
net use j: \\<machine name>\c
net use i: \\<machine name>\c
The J and I drives will be mapped in the ICA session successfully. Citrix is working to improve this functionality.
• Mapping Server 1 drives through the ICA session on Server 2: You must configure the NativeDriveMapping parameter in the .ini files or in the registry for Presentation Server Client 10 or later. To do so:
WARNING! Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.
1. Open the Registry Editor.
2. Navigate to the following registry key:
3. Create the following registry value:
