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
disconnect: Internal licensing error.

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

PLEASE, DO NOT MARK AS DUPLICATE!
Other messages from 2008year, and this is a fresh issue, only with W2k8 SP2 RDP server.

Ubuntu 9.04

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.
