How to Enable Drive Mapping Through SBS 2008 Remote Web Workplace

The Remote Web Workplace connect to computer feature in SBS 2008 by default doesn’t allow for local drive redirection. When you attempt to connect to the server or a client machine you will get the following popup showing what local resources will be available. The remote desktop connection only exposes clipboard and printer redirection by default.


In order to get local drives to be available as an option, we have to use the following steps to modify a file on the Small Business Server.

  1. Make a backup copy of the following file:
    C:\program files\windows small business server\bin\webapp\remote\tsweb.aspx
  2. Right click on notepad and choose run as Administrator.
  3. Select File > Open and browse to the following file:
    C:\program files\windows small business server\bin\webapp\remote\tsweb.aspx
  4. Search for this line:
    MsRdpClient.AdvancedSettings2.RedirectDrives = FALSE
  5. Change the line to:
    MsRdpClient.AdvancedSettings2.RedirectDrives = TRUE

    The file should look like the following:
  6. Save the file and exit notepad
  7. Log back into the remote web workplace.

Now when you use the connect to client desktop or connect to server feature you will see the following dialog allowing for local drives to be redirected.


Note: If the tsweb.aspx file is ever updated in a future hotfix or service pack, your custom changes may be lost and if so you will need to manually redo them.

  • doesn´t work. at lest in the portuguese version of sbs. In fact i get a connection error when I try to remote desktop the machine.

  • Every time I implement this it throws an an error when trying to connect.

    The error is something along the lines of you need version 6 of RDP for this connection. The problem is we all have that version.

    So it must be something wrong with the config because as soon i change it back to FALSE it works.

    Any Ideas? Would love to get this working.....


  • This should be a setting, not a customization.

    In the real SBS2008 world the servers are managed part time at best, so expecting lists of "customizations" to be tracked and monitored just isn't realistic.

    Now if I can just find where to "customize" the Pop3 connector to let me retrieve emails over 10MB in size...We never DID need more than 640k either.

  • this doesn't work at all!!!

    need rdp 6.0 or higher! which i have !


  • 1.  Close all Internet Explorer windows

    2.  Click Start, click Run , and then type or copy and paste the following text in the Open box, and click OK :

    regsvr32 %windir%\system32\mstscax.dll  

    3.  At the confirmation prompt, click OK.  

    4.  Restart Internet Explorer, and try again.

    If that doesn't work, try some of the other steps in KB 951607.
