Question

Remote desktop Disconnected!

Asked by: vcio

I am trying to get Remote Desktop to work after VPNing in to a network using Sonicwall NetExtender. I am doing it from Windows XP professional image on VMWARE on an MacBook and from an iMac. Once I connect the VPN to the network I try to use Remote Desktop. It gives me the following error:

"The client could not connect to the remote computer" "Remote connections might not be enabled or the computer might be too busy to accept new connections. It is also possible that network problems are preventing your connection."

Note: I can connect using the same id's and machine names successfully when using a machine that only runs Windows.

From where you are currently trying to rdp, can you scan the destination port 3389 if it is reachable and open?

You mentioned "I can connect using the same id's and machine names successfully when using a machine that only runs Windows"
Did you try this from vmware fusion under the same mac machine?

 

by: vcioPosted on 2009-08-18 at 20:13:28ID: 25129387

How do I do the port scan?

I am running Windows XP Professional under VMWare fusion. And connecting the VPN. Then trying to do RDP. At which point it fails as described.

 

by: ryder0707Posted on 2009-08-18 at 20:31:20ID: 25129445

portqry -n ip_address -p tcp -e 3389
get from microsoft at http://www.microsoft.com/downloads/details.aspx?familyid=89811747-C74B-4638-A2D5-AC828BDC6983&displaylang=en

if the result is filtered, something is blocking it.

cheers!

Firstly, I have to ask, can you connect and browse the internet on the VMWare Fusion installed guest OS,

You should be able to also make a pptp connection for your Mac OS directly to a sonicwall device. Are your the firewall admin. One you have this, you should then be able to connect to the remote network with the RDP client for OS X.

 

by: vcioPosted on 2009-08-19 at 06:06:16ID: 25132117

Comment to nappy_d
- I can browse the internet from the guest os. From within the windows environment I open Internet Explorer and connect to the to the firewall / SSL VPN. I am able to successfully connect to the VPN. The NetExtender client does connect successfully. The problem is in the next step where I try to use the RDP to access the machine(s) on the network I just VPNd into.

- As for connecting from the Mac OSX I have tried that and the installation of the NetExtender fails,giving the following message: "There was a problem loading the NetExtender JNI library. Please reinstall NetExtender, and make sure you have a compatible version of Java installed. SonicWALL recommends Sun Java 1.4 or higher." The machine is running Apple Java. I did not want to mess with replacing the java on the mac.

did u try portqry? if it is filtered then you know it has something to do with network

Figured it out. it was open DNS appending the local host name and not resolving the internal machine name. Change the preferred DNS to 4.2.2.1 and now it works.
