I've been using Windows Remote Desktop on my (host) Vista Business
machine for months with no problem. Recently, it stopped working and I
can't come up with an explanation. I'll detail what I've done and what I
know so far.

Remote Desktop is enabled in Remote Settings with the middle radio
button (less secure).

Checked the registry for the correct port number and changed it to see
if that fixed it -- nope.

Router is configured for port forwarding correctly (port 3389 TCP).

Can't connect from machines outside the network nor inside the network,
using internal IP, machine name, or external IP.

Remote desktop client from local machine (loopback) gives the following
error immediately when connecting to the machinename or localhost:

"The client could not connect. You are already connected to the console
of this computer. A new console session cannot be established."

When I try to remote desktop from a computer inside or outside the
network or if I type the external IP into the host machine's client I
get the generic timeout message:

"This computer can't connect to the remote computer. Try connecting
again. If the problem continues..."

What's weird is that if I type qwinsta at the command prompt, I get
this:

SESSIONNAME       USERNAME                 ID  STATE   TYPE      
DEVICE
services                                    0  Disc

From what I've read online, I should have a line in there like:

rdp-tcp                                 65536  Listen  rdpwd

I also don't show 3389 open when I run netstat -a.

I have RemotelyAnywhere and LogMeIn installed on the computer, but I've
been running the three in tandem for months without issue.

Windows firewall has the proper exceptions set, and I even tried
turning it off, but that didn't help.

I checked and the Terminal Services service is running.

Any ideas? Thanks for any and all replies, this is driving me crazy!
