Printer Redirection is not working.
Drive redirection works.
No event Ids seen
The spooler security descriptor must contain the “AU” (Authenticated User) ACL (Access Control List) which allows any authenticated user to open the spooler service for reading operations.
In this case, that ACL was missing from the spooler security descriptor.
Run the following command to show the current security descriptors on the print spooler:
C:\sc sdshow spooler
An unaltered SD (security descriptor) for print spooler should look like this:
The important ACL in this case is the one for authenitcated user (AU), since TS runs as a network service it relies on this ACL to be present in order to successfully open the spooler service. Adding the following ACL back fixed the problem.
Following is the method that can be implemented to add the missing ACL.
Run the following command:
c:\>sc sdshow spooler >temp.txt
You would see all the ACLs except for the "(A;;CCLCSWLOCRRC;;;AU)" ACL when you open the text file.
Following is an example: (you may see a different output depending on the permissions set on the spooler)
You could then copy the above output in a notepad as follows:
sc sdset spooler D: (A;;CCLCSWLOCRRC;;;AU)(A;;CCLCSWLOCRRC;;;AU)(A;;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;BA)(A;;CCLCSWRPWPDTLOCRRC;;;SY)
Note: Please ensure that you are appending the "sc sdset spooler D: (A;;CCLCSWLOCRRC;;;AU)" section of above command to the output you see in your case.
Copy and paste this command in the command prompt. (please ensure that "(A;;CCLCSWLOCRRC;;;AU)" appears in the beginning. I'm not sure why this is the way it seems to work.)
By running the above command you retain the old ACLs and also add the missing ACL that is the one for authenitcated user (AU).
Following is a list of some more things that can be looked into in an "Printer Redirection not working" issue:
1) If the client machines are running Windows XP, ensure that .Net Framework 3.5 SP1 is installed and at least RDC 6.1 is being used.
2) Even if RDC 6.1 or above is used, the user ,ust install a supported version of .NET Framework separately. Microsoft .NET Framework 3.5 (which
includes .NET Framework 3.0 SP1) can be downloaded from the Microsoft Download Center (http://go.microsoft.com/fwlink/?LinkId=109422 ).
3) If you connect over RD Gateway, ensure that the policy that disables printer redirection is turned off
4) If your server is also a domain controller refer: http://support.microsoft.com/kb/968605
5) Group Policy must be correctly set to enable Easy Print on the Server. The policy location is “Computer Configuration -> Administrative templates -
Windows Components -> Remote Desktop Services > Remote Desktop Session Host -> Printer Redirection”. The setting “Use Remote Desktop Easy
Print printer driver first” must be set to “Enabled” for Easy Print redirection, and it has to be “Disabled” for Legacy Print. For “Not configured”, Easy
Print is chosen by default.
6) Make sure that the “Printers” check box in the client (mstsc.exe) window on the “Local Resources” tab is checked. The corresponding setting in the
associated RDP file is “redirectprinters:i:1”.
