[rdesktop-users] Can No Longer Establish Connection

[<Joh...@da...>]

I have what had been a long working setup using rdesktop (1.8.0 on Fedora 
19) to connect to a notebook running Windows 7 Enterprise (on SP1, but I 
don't know for how long).  I'm pretty sure recent updates to the notebook 
caused my issue, but I am seeking help here because I really need to get 
this working again and have little faith that my IT support will be of 
much help, especially given the last bullet point below.

Here's what I know:

rdesktop never even creates a window
running from a shell prompt, I see only the following on stdout:
Autoselected keyboard map en-us
Connection established using CredSSP.
the exit status value ($?) is 76
telnet notebook 3389 is able to connect so basic TCP/IP and firewall type 
issues are out
other coworkers have attempted a connection to my notebook and get the 
same results that I do
any attempted connection does result in the session being "stolen" from 
the notebook's screen; but at the same time, it never appears remotely 
either
I tried downgrading back to rdesktop-1.7.1 even though I'd used 1.8.0 for 
around a month; this downgrade also made no difference
I can recompile with various debug options enabled, but I have no idea 
what would be useful here so please specify, if needed -- I tried all but 
nothing caught my eye other than a "Failed to parse crypt info" right near 
the end.
an strace of the process seems to show that rdesktop is waiting forever to 
read something from the X11 server socket
a coworker was able to connect remotely to my notebook from his notebook 
(also Win 7) using mstsc


Many thanks in advance for any guidance.
