WM6: Ok, VPN: Ok, Remote Desktop: NOT Ok - HELP

Hello all,
I have been successful in loading the WM6 ROM: works great! I have been successful at using the phone for Bluetooth DUN. I have been successfull at setting up a VPN connection to my place of employment: I can look at the RRAS server GUI and see that I have established a viable connection.
What I have NOT been successful at is getting Remote Desktop to work. RD is one of the reasons I upgraded to this ROM. Has any one been able to get their Windows desktop on their Treo? If so, how did you do it?
I can't seem to find any pertinent information on how to make this work so anything you can tell me would be a great help.
Cheers,
idyllic

Joannaex,
thank you for the forum pointers. Alas, they did not help. I did try to load the cab file from one of the threads, but it loaded the same version of Remote Desktop Mobile that I already had. I still get the same errors encountered with the previous version. Maybe this behavior is due to the "unofficial" ROM not being fully functional in some way? I don't know. It would be interesting to hear from someone that actually got this to work.
Cheers

PS: in occurs to me that this might be a routing issue in the 10.x.x.x/192.x.x.x space. I could verify this if there were a command prompt where I could run things like ipconfig, tracert, netstat, etc. Or a log file that could be viewed. Just wishful thoughts I suppose
PPS: Just found two great progs, one called VXIPCONFIG which give you the info you would get in you did an ipconfig /all. The other is called VXUTIL which you can do PING, TRACERT, WHOIS and a lot more. The utilities are available from http://www.cam.com/windowdsce.html.

I have been able to connect to remote desktop. What has been successful for me has been to already initiate my 3G connection then connect using remote desktop. It doesn't seem to be able to start up the connection itself.

andokia,
I am doing the exact same thing: starting my 3G connection, then my VPN connection, and lastly Remote Desktop Mobile. The RDN ALWAYS times out with one of these two errors: "Connection Status - Cannot Connect. Likely reasons are: 1. Specified computer name or IP does not exist, 2. A network error occurred while establishing a connection." So, I'm kind of at a loss here as the troubleshooting tools available are not great. Thank you for the response!

Hi idyllic,
Can you access a remote desktop when a VPN session isn't active? I have used the two separately without problems but haven't tried them together.

andokia,
no, I cannot access any system. I have tried my home system (firewalls turned off and on). I have tried my work systems (VPN on and off). Nothing seems to work. It's really frustrating to have a tool that you know can help you, but it doesn't work: aaaaaaaaaaaahhhhhhhhhhhhhhhhhhhhhhhh!

I'm assuming you're trying to use a local address because you are connecting with vpn first. Did you put the local address in the exceptions list? If not the vpn connection will disconnect anytime you try to use an address that is not in the exceptions list.
Exceptions list: start\settings\connections\connections\advanced\exceptions
then add the local url
Hope this helps. Used to be the problem I had when trying to use VPN.

chris44gw,
yes, I'm trying to connect to a local addres, but that address isn't a URL. The address I'm entering is an IP address of the machine for which I want to get a desktop. Now maybe I'm wrong, but my understanding is that I can use Remote Desktop Mobile to get, say, a desktop/console of one of my servers.
I've been able to surf the web on the phone, I've been able to use the phone as a Bluetooth modem, I've been able to connect to each of my companies VPN servers. Still now desktop. Whether I enter a fully qualified domain name or an IP address it never works.
Now, I have a little more information. If I just connect to the AT&T 3G network I can do a traceroute to the VPN servers. If I then connect to the VPN (PPTP connection verfied and active) I CANNOT ping anything on the corp. net. It has to be a routing issue I'm thinking. It seems that it needs to be fixed on the phone side, but I can't seem to figure out where to do this.
Anyway, I appreciate the pointer about the URL exception list.
Cheers,

That's what mine looks like. Once I'm connected vpn wise into my 2003 server I can RDP into it and another XP machine on the network through the local IP. Only thing I can think of is if you have activesync connecting to an exchange server. It might disconnect the vpn. I think you've said you're verifying the vpn connections so I might look into the firewall on the computer or make sure RDP is on for the computer (although you've probably done that). Good luck though.

chris44gw,
thank you for the screen-shot. I gave this a try, but no luck. We don't use exchange servers at work and I've verified that no active sync is active during the connect process. Having downloaded a couple of tools to help troubleshoot, I've noticed that I CANNOT ping anything on the internal network: this after verify that the VPN connection active and viable. I have also verified that each system that I am connecting to has RDP turned on. I guess I'll just keep experimenting. I just can't help but think that there is ONE LITTLE THING that is keeping this from working.

PS: What encryption level does the Treo 750 VPN app use? 56bit? 128?
PPS: Upon further testing... when I connect to the RRAS server (and connecting to the RRAS server has NEVER been the problem) on the West Coast (Windows 2000 Server std. SP4) I cannot ping the "inside" network. When I connect to the East coast RRAS server (Windows Server 2003 SP2) I CAN ping "inside" network. In either case I still cannot get a remote desktop.

Have the same problem on Diamond
Hi all,
After upgrading to wm6.1 on O2 Diamond unable connect to Remote Desktop.
When manually connected to Internet it works perfect, but from RD Client there is always an error (dial up or Proxy settings). All other programmes can always correctly initiate internet connection via GPRS/UMTS. Via Active sync RD works always.
MFG

Sorry, never got it to work. Call me a traitor, but I now have an iPhone and everything works the way I expect it... with two major exceptions: 1. no cut-and-paste, 2. can't be used as a tethered modem without jail-breaking the phone (which I'm not willing to do).

Similar problem HTC Touch HD
Hi all, sorry in advance if my problem ends up being because I've missed something basic; I'm trying to setup RDC on my HTC Touch HD with no luck. Computer name is right, password is right, IP is right. Fail message:
"connection status. cannot connect. likely reasons are: 1. specified computer name or ip does not exist. 2. A network error occurred while establishing the connection."
I'm connected to my WiFi network which also has the machine i'm trying to connect to on it. I've also tried when out of network range, connecting via 3G/HSDPA. Steps I've taken:
-Enabled remote desktop in system properties on target machine. Haven't added any remote users as it already allows me (admin on target machine) and I'm using those login details to access.
-Allowed RD in the packet settings of Kaspersky antivirus, using the address as the ip of my mobile, found by going to whatsmyip.com, and name as the name I've set on the device.
-Probably unrelatedly, I've also allowed the HTC to access the wifi through the MAC address access list
I can connect via a standard windows machine on the same router (which just needs the computer name, not the IP). Have found this useful as I had the details around the wrong way, but even now it's not working. Based on the tips in the link above, I'm under the impression that I should set things up thus:
Computer: the ip address of target machine
User name: EITHER my username OR MACHINENAME/User Name, e.g. John Smith OR JOHNSPC\John Smith
Password: pw
Domain: either machinename or blank.
Anyone know if this is right / which of the options for username and domain is right?

Remote Desktop Mobile

Hi guys,
I've searched LOADS of threads but to no avail.
I have installed RDM, but can't get it to connect. The PC is XP PRP, and my laptop connects ok (running Vista), but with the same settings on my MDA III, it refuses with the error:
"Cannot connect. Likely reasons are:
1. Specified computer name or ip does not exist
2. A network error occurred while establishing the connection."
I've checked all my settings, left DOMAIN blank, disabled firewall etc.
Router is a NetGear.
Thanks guys

Couple of questions... (excuse me if some of these come across quite basic)
Is your laptop that works within your internal network or from an external network?
To what IP address are you trying to connect to (ie. should NOT be an internal 192.168.x.x or 10.3.x.x address)?
Do you have port forwarding or a DMZ enabled on your router?
Are you assigned a static IP address from your provider?

sorry - bit more info...
how are you trying to connect - wifi? over the air?
if wifi, can you get a general data connection through the router?

HTH, thanks for the response.

hmmm...
excuse me if i'm asking silly questions which you may have already tried...
is remote desktop enambled under 'system properties - remote' on the xp machine?
have you tried connecting using the IP address (192.168.whaterver) of the XP machine as opposed to the PC name?

FANTASTIC!
Worked with the i.p. address
Thanks buddy!!!!

no problemo...

I am having the same problems, but I can get a little bit further, I believe connected, but error message,
"The system could not log you on. Make sure your log on and password are correct, etc. With the little magnifing window on the lower right, then is disconnects after a bit. I use the correct password and case that I use to succesfully connect from other computers. I am stumped.

a little late I know......but when I get this error while using GPRS/3G to connect........I just initiate an internet connection using the IE button.....then with that running go to start menu and execute the remote desktop again.......and it connects fine.
a little bit of trouble but that is my work around for it.

this might be asking alot but i'm trying to connect via wifi and it won't connect.
I have all the info needed only I cant set the port forwarding on my router. It's a D-link DIR-655..
Can anyone help?

No port forwarding, no can do. That router has to know which IP needs that port.

Remote Desktop

Hey all.
I've tried searching Google and the XDA, but I still can't seem to get my remote desktop to work.
I'm using the AT&T version (Fuze) and Windows XP Media Center Edition. I went through the steps on my PC to enable and allow RD in the system and firewall sections, and still keep getting the "Cannot connect" error message when I try and use RD on my Diamond. Any advice?
All stock ROM, progs, etc.
Thanks!

If it's anything like T-Mobile in the UK, Remote Desktop may be something blocked at the carrier.
I managed to get around it using an SSH tunnel. It's not actually as difficult as it sounds I describe what I did in this post:
http://forum.xda-developers.com/showthread.php?t=357009&page=2
Before that I'd try connecting to remote desktop through a wifi connection which you know allows RDP, just to make sure your cellular network is at fault. If it is, you could try complaining - some people on T-Mobile UK have had RDP enabled on their "standard" data contracts which aren't technically supposed to have it from what I have heard.

Hey, thanks for the tips.
I actually tried it on a WiFi connection and got the same result.
I'll try looking into your other suggestion, but aside from that, are there any other troubleshooting options? Thanks all!

See if another computer can remote into your computer. It might not be an issue with your phone.

I was able to connect using another computer in the house...they're not networked but using the same internet connection. Gonna try and have my cousin connect to my comp from his house when he gets home...but so far it doesn't seem like it's my computer...

Still need assistance.
Thanks!

try it without the router. u probably need port fordwarding.

You will also need either a static ip address from your isp or setup dynamic dns resolution (i.e dyndns.org). If you have a dynamic ip address the ip address of your router is issued by your isp every time you connect(not neccessarily a different ip every time, but it might be). As mentioned above you will aslo need to setup port forwarding on your router for port 3389 (default rdp port) to the ip address of the machine you want to remote onto.

Forgive me but...how do you set all that up?
I appreciate all the assistance thus far!

I couldnt get mine to work, so I forward port 5900 on my PC and use RealVNC (free/shareware)

Hello:
I'm also having problems getting my remote desktop to work. Been trying to connect since I picked up my Fuze on the 11th.
I have three different computers that I can successfully administer via my desktop. I've tried using 3G to connect, no success. I've tried using Wi-fi to connect, no success. I've used local computer names, IP addresses, properly forwarded ports --
It has to be a setting I'm missing on the phone. Any ideas? TIA
(and yes, I'm sorry, I know this is the Diamond forum, it's just the only thread I've found)

VPN connection (PPTP)

Hi there. Please anyone if has info on this:
Have you ever managed to connect through VPN and PPTP on a windows VPN server? And if yes HOW?
I have tried thousand of times to set My work network settings and nothing...
Thanks in advance
P.S. It seems it tries the connection, on the server side i CAN see the connection established but from the mobile side it seems to drop..

have also had problems gave up in the end but would love to get this working, anyone got a top three list of best VPN clients

SO... its a telephone company GAME.. another one!!!
They DONT let VPN passthough..!!!!!!! If someone wants to connect with VPN to his office/home needs another packet to activate (Cosmote Greece) which costs the same as the internet connection!!! They just want our money!!!
If i try this connection (VPN) through wireless internet works just fine!!!

Make sure that you open up the port on your computer's firewall, your router, and anything else that might have a say in your internet traffic.
I'm not going to explain it, but Google "port forwarding".

im in the campus dorms
i dont think i can do any port forwarding as i dont know how the whole lan thing is set up here
thanks

i am currently having the same problem ...i have forwarded the port 5900 on my router and opened up my firewall...could i possibly have to do something to the modem as well or could it be something else
i am on a I touch 3g slide and running windows xp home
i have also heard that port tunneling may be neccesary but i lack the knowledge to do so any help would be appreciated

its all about port forwarding because you have dynamic ip addresses on the LAN side and most likely you have a dynamic WAN ip also. Usually to do VNC you have to have a Public IP address. Home ADSL circuits provide one public ip address but out of a NAT pool so it will change. This could cause an issue unless you want to check the destinations ip address everyday. So instead of VNC to an ip address you can vnc to a host name. Dyndns provides a good service for free. So that solves the dynamic IP issue.
Now to the port issue. Since the internal LAN will assign each host a 192.xxx.xxx.xxx ip address (which are not publicly routed), you have to do port forwarding. To do this go to the command prompt (start>run>cmd) and type in "ipconfig /all" and press enter. Find the default gateway ip address (192.xxx.xxx.xxx). Type that into the web browser. That will log you into your router. I have a 2wire router provided by att so if you have different you will have to discover this on your on. Go to firewall settings and then add a new user-defined application. basically make a new application.
protocol tcp
port range 5900 (i believe that is right)
and then add it to the correct computer.
That should send all data on that port to that host.
Hope that has helped a little bit. if not, google it.

You may want to give up with that and try out PhoneMyPC. I'm not 100% sure of how they do their tunneling, but I can tell you I've tested it a few times and it always manages to get through even if I purposely change WAN ip addresses and I don't do any port forwarding for it.
It also runs way faster (albeit lower resolution, i think) and more fluidly than either of the RDP or VNC solutions I tried out. I'm very impressed with it so far. I can even jump online with it and pull up my security camera software and actually see the live video feed from it, all running on my PC at home, even just over a 3G connection.
