Remote Desktop to Windows XP workstation

[Guest]

Okay has any one ran into this issue. I have Windows Vista Business on my
laptop, when I try to remote desktop into a Windows Xp workstation that I was
able to remote into before I get the message "The computer can't connect to
the remote computer

Try connecting again. If the problem continues, contact the owner of the
remote computer or your network administrator"

As I said accessing the computer worked before via RDP all of a sudden it
stopped. I can access other XP workstation via my Vista laptop with no
problem. It seems to be something with Vista and this XP workstation although
I have tried other XP workstations and I am able to get access. I have
searched all forums and took some of their suggestions but nothing works
(there is a lot of issue with RDP 6.0 out there). Can anyone help me please!!!

Som of the items I have checked made sure Remote access on the XP
workstation had not been changed. Installed the latest RCP 6.0 on the XP
workstation to see if this rectified the issue.

Since you can RDP from Vista into other XP machines, we can assume that RDP
is running okay on your Vista machine. So now, we move on to basic
troubleshooting ...

Is the basic network connectivity between the Vista nd XP machine okay? test
with ping; at a command prompt on Vista:

C:\>ping <IP address> // where IP address is the address of XP machine
eg
C:\>ping 192.168.0.10

If this fails, there is a basic network connectivity problem in the
physical, data link or network layers.

If it works okay, move on to name resolution:

C:\>ping <machine name> (where "machine name"IP address is the
address of XP machine)
eg
C:\>ping GroovyXP1

If this fails, there is a problem with name resolution. You need to check
your DNS settings, and see if the ame name is recognised from other machines
as well (maybe the XP machine is not registering in DNS?)

Assuming you can ping bthe XP machine by name, we know that basic network
connection is okay and name resolution is okay. So the problem must be
somewhere in the TCP or higher layers.

RDP goes over TCP Port 3389. By default, this is turned OFF in XP. It should
be enabled when Remote Desktop is tunred on, but, hey ... anyway on the XP
machine go to Control Panel, System, Remote and make sure the "Allow users
to connect remotely to this computer" is turned ON. Next, go to Control
Panel. Windows Firewall, Exceptions, and make sure that "Remote Desktop" is
checked, as an exception.

Next, make sure that TermServ service is active on the XP machine (this is
the service which listens for incoming RDP requests). At a acommnd prompt on
teh XP machine, do:

C:\>netstat -ano | findstr 3389

to find all processes active on TCP Port 3389. You should see something
like:

C:\Documents and Settings\User>netstat -ano | findstr 3389
TCP 0.0.0.0:3389 0.0.0.0:0 LISTENING
848

where "848" is the Process ID of the process listening on port 3389 (you
will probably get a different number than 848).

Next, see what Process Number 848 (or whichever PID you got from Netstat)
is:

C:\>tasklist /svc

Look down the list of processes for one with a PID of <PID>, eg in my case
848, or whatever was returned when you ran Netstat. You should see something
like:

C:\Documents and Settings\User>tasklist /svc

Image Name PID Services
========================= ======
=============================================
System Idle Process 0 N/A
System 4 N/A
<snip>
svchost.exe 848 DcomLaunch, TermService
svchost.exe 916 RpcSs
svchost.exe 1012 AudioSrv, BITS, CryptSvc, Dhcp, dmserver,
<snip>

The important bit you're looking for is "TermService". It is actually hosted
within a generic process called SvcHost.exe.

If TermServuice is active and listening on port 3389, and the firewall has
3389 open, and RDP works from Vista to other machines, and you still cannot
connect to this XP machine, then ... sorry; buggered if I know!! :-( A
nework trace using NetMon would soon reveal the problem; but that's too hard
to describe in a newsgroup. Find a friendly local geek who like sniffing
networks. Or, look in the Event Log in both the XP and Vista machines, to
see if any events were logged to indicate why Remote Desktop failed go to
Control Panel, Administrative Tools, Event Viewer. Look under Application
Events and System events - ccould be clues in either.

Good luck, hope it helps,

Is there any wireless stuff involved? Some wireless drivers break a
protocol and there's a simple fix. I notice the error message doesn't
always lead you toward the real problem sometimes

I don't think this is the problem but if nothing else works ...

Well... if you can "hit" other XP boxes using RD... then one must assume
it's not a problem on the Vista box. One must assume something changed on
the target XP box that is preventing you from RD'ing in from the Vista box.
Can you RD into the problem box from a different box, XP or Vista?

Thanks for th help Andrew, but I tried all the items you posted and it all
looks fine. I can ping the ip and name so DNS is working. I did the netstat
command and it looks like it is listening on port 3389 and also Termserv is
in the tasklist. Nothing shows up in the Event Viewer which is not normal,
ist is almost like it is not getting to the workstation.

Where can I get the netmon utility to monitor the network?

Sorry no wireless on the XP workstation, would the file work on Vista. I have
a Vista laptop with wireless.

I tried another XP box with no luck. I am running a virus scan on the XP
workstation to see if I find anything on the workstation that maybe blocking
port 3389.

One more thing I thought you could try. Make a telnet connection to Port
3389 on the XP machine. This would help isolate whether it is some kind of
networking issue, or something in the configuration of Remote Desktop.

First, I'm assuming that other machines, say other XP machines, can Remote
Desktop into the "problem" XP machine - right? The problem is specific to
that particular Vista-XP machine pair? Or do other machines also hit the
same problem, when RDP'ing to the XP box?

On Vista, the Telnet Client is not installed by default (unlike 2000 and
XP). You need to go into Control Panel, Programs and Feartures, Windows
Features On or Off. and select to install Telnet client (if you don't
already have it installed).

Then telnet to the XP machine, giving the RDP Port as a command line
parameter; for example:

C:\Users\amclaren>telnet xpvm 3389

If it waits for 20 or so seconds and gives an error message:

Connecting To xpvm...Could not open connection to the host, on port
3389: Connect failed

.... then there is a basic network block between the 2 machines such as a
firewall or router, which is blocking access.

If telnet suceeds, you'll just get a blank window and a flsahing cursor.
It's not much confirmation, but telnet has been able to connect. In this
case the problem is more related to the configuration of RDP itself, rather
than the network.

Where can I get the netmon utility to monitor the network?

Just to set expectations, I can't undertake to analyse the trace for you - I
do that for a living, so I charge people money for it But if you're
familiar with networking, it should all be pretty straightfoward. You're
looking for some kind of error in the TCP session or RDP session between the
addresses of the Vista Box, and the XP Box.

Well... good luck with that... let the group know your findings.

Ran a virus scan and spyware scan and both did not find any virus or spyware.

Okay an update tried the telnet feature and I was getting message as above.
Downloaded Port Reporter from Microsoft and did some tests from other xp
machine it does not even register that the xp machine is going to port 3389,
since the reporter shows no activity on the port.

Changed the port on the xp machine that is giving the problem to another
port in the registry and still no luck accessing the machine. Is there a way
I can deinstall RDP from XP via the XP install disk and do a reinstall?

Only other alternative is to look at all the files that RDP uses and see if
I can copy the files from a working XP machine to the none working xp
workstation.

One other item I was able to access another XP and Vista workstation using
RDP from the none working xp machine, real puzzling. I think I may have to
contact Microsoft on this one.

Okay an update tried the telnet feature and I was getting message as
above.

You mean you got this meassage? -
"Connecting To <machine>...Could not open connection to the host, on
port 3389: Connect failed"
Right?

Downloaded Port Reporter from Microsoft and did some tests from other xp
machine it does not even register that the xp machine is going to port
3389,
since the reporter shows no activity on the port.

You mean, you were running Port Reporter on the "problem" XP machine, and
you did not see any activity when you tried to RDP in from another machine?
Right?

But earlier, you'd verified that TermService was listening on Port 3389 on
the same XP machine. So - putting 2 and 2 together - that makes it sound
like RDP network traffic is not even reaching the XP machine. Even if
another app had seized 3389 on the XP machine, you should still see
something in Port Reporter.

If it was me, I'd ...
- put NetMon onto the "problem" XP box and start a trace, capturing all
traffic to/from the XP's network card address.
- try to RDP (or even Telnet to port 3389) from another machine to te XP
machine
- observe the point of failure (eg error on RDP client machine)
- stop the network trace.
- examine the trace to see if any traffic arrived from the client machine -
especially (but not exclusively) on Port 3389.

If there are no frames in teh trace with a destination of the the "problem"
XP machine's IP address and Port 3389, then traffic isn't even reaching the
machine.

It's always hard to be 100% sure based on newsgroup descriptions - but to
me, it sounds more like some kind of neworking error, than a problem with
RDP on the XP machine. Are all the machines attached to the same switch? Are
they on VLANs? What iosteh MAC-layer topology? If you reloacte tehXP machine
to a different port on the same switch as the RDP client, does it start
working?

I guess one thing is clear (given that tthis goup is
microsoft.public.windows.vista.general) - the Vista machine is working okay;
it's the XP machine which is experiencing problems.

Changed the port on the xp machine that is giving the problem to another
port in the registry and still no luck accessing the machine. Is there a
way
I can deinstall RDP from XP via the XP install disk and do a reinstall?
Only other alternative is to look at all the files that RDP uses and see
if
I can copy the files from a working XP machine to the none working xp
workstation.

If my theory is correct, then messing with RDP on the XP machine won't
change anything. It is the netwrok which needs to be fixed.

Likewise, you could try Microsoft PSS ... but it sounds more like a
networking/deployment issue rather than a defect in the Microsoft software,
as such. So you might be better off getting your local IT guys to work on
the problem. Just a thought ...

Good luck with it!
