Remote Destop suddenly won't connect on any port other than 3389.

[john]

I have a PC that I've been using Remote Desktop on successfully for
months. Then suddenly it's stopped working. I had the PC listening
on port 443. Now when I try to connect to it on port 443 (or any port
other than 3389) I get the following error message:

"The Remote connection has timed out. Please try connecting to the
remote computer again."

If I try to connect on a port that it is not listening on, I get the
expected error message. So, it looks like it's trying to connect, but
maybe immediately times out when it's not on port 3389(?).

I have XP's ICF turned off. I have a network bridge. I have no
personal firewall and have not changed my routers' configurations. I
have another computer that did and still does work as a Remote Desktop
server on a port other than 3389, so I think the problem is PC
specific.

Does anyone have any idea why this could be happening?

It's driving me crazy.

(BTW, I'm going through all this trouble so I can connect to the
computer from my work, and therefore have to use a port that's open in
my workplace's firewall)

Thanks,
Johnny

Did you do a system restore to a restore point past the date in which
you changed the listening port? Also, make sure you verify that the
listening ports are still properly set in your computer.

See http://support.microsoft.com/?kbid=306759 for more information on
how to do this...

I do not have a restore.
The registry is how I've been changing the port (and rebooting after
changing).

Here's another interesting piece of info. I just downloaded some
software called Advanced Port Scanner v1.2 and ran it on both
computers. On the computer that works fine the results were that all
ports are closed. On the computer giving me trouble the results said
that ports 21, 25, 80, 135, 139, 445 and 1025 are open and all others
are closed. Any idea why this difference would exist? I looked but
don't see any software or processes running that (as far as I know)
would be opening/blocking ports.

Thanks.

Hi,

I am having similar problems connecting as well. Before I
could use remote desktop without a hitch but suddenly I am
unable to do so. I was hit by the sasser virus on the
machine lately as well, but I fixed that however the
remote desktop connection problems persist!

21, 25, and 80 are IIS
135/139 are Windows RPC/File Sharing/etc.

Are you scanning inside or outside of the firewall (i.e., using a
public or private IP address)?

Both machines are on the same internal network (no firewalls).
Yes, I am running IIS on the trouble PC. Could this be what's causing
the differences in Advanced Port Scanners report of open ports?

Also, I can browse the hard drives/folders of each computer from each
computer, if that helps.

Thanks.

Figured it out.
It was because IIS was running. I disabled IIS and now can connect again.

I'm glad you are able to connect...

What is IIS, how can I tell whether or not it is running, and how can I
disable it if it is running?

IIS = Internet Information Services (i.e., the Web Server).

See http://www.microsoft.com/security/bulletins/howtotell_iis.mspx for
information to see if it is installed/running.
