Summary: Can't connect to WinServ 2008 SP2: "internal license error"

Initial Comment:
Today, after update my win 2008 server to SP2, my rdesktop failed to connect.

$ rdesktop -d rimsco -u "admin" -p pass -g 90% 192.168.1.3
Autoselected keyboard map ru

When I remove ~/.rdesktop/license.<hostname> I can connect ONLY ONE TIME, and after disconnect it fail again.

PLEASE, DO NOT MARK AS DUPLICATE!

Message:
I had the same issue, and the solution proposed by "leecoles" worked fine
for me:

Connect to the Windows 2008 server, open Administrative Tools -> Terminal
Services -> Terminal Services Configuration.  If necessary, select the root
of the configuration tree on the left panel (that is: click "Terminal
Services Configuration").  Then click "Terminal Services Licensing Mode"
(under "Licensing", on main panel) and change it to "Per User".  The
problem is gone! ;)

Dear All

I came across this issue myself and it seems to only occur if you Windows
Terminal Server has its Client Access Licences in "Device" mode. I assuming
in this mode a file needs to be written locally on Linux and this is where
the issue comes. It you are able to change the licensing mode to "User" on
your Windows Machine then this issue goes away as no file needs to be
written.

Regards

Lee

Message:
I can confirm that problem still exists with rdesktop 1.7.0.
If I connect to Windows Server 2008, all is going okay (but for some reason
rdesktop doesn't even create ~/.rdesktop directory).
But if I connect to Windows Server 2008R2, such message appears:

disconnect: Internal licensing error

Deleting ~/.rdesktop directory and creating a file with the same name is a
workaround (prevents rdesktop from storing license), but of course it is
not a solution.

Message:
I have tested rdesktop 1.7.0 and it behaves the same way. If no license
file is present, it can connect. if one is present (even one created by
1.7.0) it fails with the internal licensing error. (ubuntu 10.10, 64bit)

Message:
Our workaround is like the one from xmasterx but without the requirement of
root rights

Remove/Delete the ".rdesktop"-directory 
# rm -rf ~/.rdesktop
and create a _file_
# touch ~/.rdesktop

rdesktop will complain that
  /home/<user>/.rdesktop
is not a directory but it will continue without writing the license file :)

I have the same problem. I can only connect once… Then I have the :
Internal licensing error.

But the distribution for Igel Thinclients use rdesktop version 1.6.0.5 and
they have no problem to connect to a licensed windows 2008 server.

Is a official Patch existing?

Thanks

Message:
The workarround that I find, until a patch for this bug is released, is to
do:

# chown -R root.root /home/<username-with-problems-here>/.rdesktop

and just is case:

# chmod -R 444 /home/<username-with-problems-here>/.rdesktop

then just delete the license.<hostname> file and it work like a charm :D


I'm using rdesktop 1.6.0 with Ubuntu 9.04, trying to connect to a Windows
2008 Enterprise 32bit Portuguese with SP2.

Message:
I checked in [MS-RDPELE] and I found this on page 82:

"<1> Section 1.3.3.3: The License PDU flow for personal terminal servers
described in this section is
valid for only Windows Server 2008 R2 and Windows 7 client operating
systems. Similarly, the
licensing architecture (section 1.3.1) and license PDU flow (section 1.3.3)
for personal terminal
servers exist in Windows Server 2008 R2 and Windows 7 client operating
systems only.
For previous versions of Windows, the personal terminal server does not
require a CAL and sends a
license error message (see [MS-RDPBCGR] section 2.2.1.12.1.3) with the
dwErrorCode field set to
STATUS_VALID_CLIENT (0x00000007)."

This most likely is the source of the problem.
