svn commit: r1030163 - /incubator/vcl/trunk/managementnode/lib/VCL/Module/OS/Windows.pm

[ar...@apache.org]

Author: arkurth
Date: Tue Nov  2 18:30:20 2010
New Revision: 1030163

URL: http://svn.apache.org/viewvc?rev=1030163&view=rev
Log:
VCL-373
Added Windows.pm::enable_rdp_audio subroutine and added call to pre_capture.  Audio redirection is disabled by default for RDP sessions under Windows Server 2008.  This should allow audio to work as expected.
