Error 720: A connection to the remote computer could not be established.

So I got an aircard Novatel P720. It was working fine for months. Then I installed a VPN connection. Now, I get this error.
Error 720: A connection to the remote computer could not be established.
Most of of what I found recommends uninstalling the WAN Miniport (IP), it seems that I have to go thru so many hoops to get this fixed. Wondering if I would be better off rebuilding my machine from scratch again. Is there an patch or another way to get me going.
I think this is an old issue. Lots of comments on this thru Google. I am hoping I can get a definative answer from Lenovo's itself!

Well, seeing since your having an Issue with a non Lenovo product. I dont think your going to get an official answer from Lenovo. You may get suggestions however.

Windows VPN: Error 720 - A connection to the remote computer could not be established

Dear all
I have a windows7 Laptop 64bit Dell 1340.
I was working with a UMTS card, was connected with a VPN to a windows 2003 server over PPTP and experienced a bluescreen. After this, I have the following errors when connecting to the VPN:
"Registering your computer on the network... Error 720: A connection to the remote computer could not be established. You might need to change the network settings for this connection"
and in the event view I receive the following:
EventID: 1, Source RasSstp
CoId={A3478DFD-FFA4-4E8F-9DA3-CE829BDA777B}:The initial Secure Socket Tunneling Protocol request could not be successfully sent to the server. This can be due to network connectivity issues or certificate (trust) issues. The detailed error message is provided below. Correct the problem and try again.
I tried to use the Rarepair.exe tool but it looks to work only on windows xp. I deleted the IP and TCP settings without any luck.
I run a registry cleaner as well with out any luck.
Your help will be greatly appreciated!

Hi,
Since it worked previously, a quick solution is to run System Restore and get back to the previous status when the issue didn’t occur.
If system restore doesn’t help, please also try the following:
1. Check if you can establish the VPN via other connections except the connection through the UMTS card.
2. Reset the PPTP and L2TP WAN miniport with running the following commands one by one in an elevated command prompt:
Netcfg -u MS_L2TP
Netcfg -u MS_PPTP
Netcfg -l %windir%\inf\netrast.inf -c p -i MS_PPTP
Netcfg -l %windir%\inf\netrast.inf -c p -i MS_L2TP
Then reboot the computer and see how it works.
Meanwhile, I would like to share the following with you for your reference:

Error 720 a connection to the remote computer could not be established win 8

hello, i have this error on my windose 8, error 720 a connection to the remote computer could not be established ,for VPN connection, how can i fix it ?

Hi，
For this issue,I would like to know your VPN protocol.
Did you use Windows in-built VPN client?
I think the issue is related to your security software or Firewall.
Let’s temporarily disable other security software and Windows firewall to check if that helps.
If it doesn't work, please uninstall the third-party security software or firewall to test it.
Also, please check your event view to see if there are some related error in it.

VPN ERROR 619 :: A connection to the remote computer could not be established, so the port used for this connection was closed

I have been searching endlessly for this issue. Every time I try to connect to a VPN connection I get the error above. Thank you for any relevant input concerning this matter. My NIC is Qualcomm Atheros and I'm in Win8.1 x64.

everything normal before?
is there any changes before this issue happen?
turn off your antivirus and firewall, update the latest VPN client software, if still not working go to security settings and change the VPN type automatic to PPTP. And also change data encryption configuration to Optional and select CHAP & MS-CHAP v2.
If still not working try with other internet connection and try to contact your VPN provider

The remote computer could not be found. please contact your helpdesk

RDS Farm set up as follows 3- RD Session Host/Web servers set up as network load balanced and 2-RD Connection broker servers set up as clustered servers. I access the RdWeb farm from the internet via VPN clientless. I can get into
RdWeb with no problems, however I have few clients that can connect to RdWeb portal but once they open any application icon the error gets displayed "the remote computer could not be found. please contact your helpdesk ". The client
pc is Windows 8 with IE11 and Windows 7 with IE 10. I could not find anything that related to some users that could not connect. Help!

Hi,
Firstly please provide some more information from your side.
1. Does the other user can able to work properly without any issue?
2. Did you install the RD gateway role to allow the external user to access the internal resource? If so, please help to make sure you configure the FQDN for the RD gateway, and the external users can resolve this name on the internet.
3. Can you telnet the RD host server (like telnet server name 3389) to check whether the RD host server is available for another server?
4. Did you try to temporarily disable all of firewall and anti-virus to test if this issue persists?
You can configure RD Web Access behavior on IIS manager as per below.
IIS Manager Console > Default Web Site > RDWeb > Pages > Application Settings > DefaultTSGateway > add the "FQDN of the Remote Desktop Gateway"
After finishing all above steps, please launch the RemoteApp again to see if the same issue still exists. For more information, you can refer beneath article.
Configure Remote Desktop Web Connection Behavior
Hope it helps!
Thanks.

A connection to the QuickTime server could not be established. This computer may be having trouble accessing the Internet or the server may be offline

When I select “Update existing software in QuickTime Pro I get an error message saying “A connection to the QuickTime server could not be established. This computer may be having trouble accessing the Internet or the server may be offline”
This has persisted for several weeks. Any help will be welcomed as I do not know how to contact QuickTime support via Apple.
I am using Windows 7 64 bit.
Many thanks

I was able to download and install the latest version of iTunes (10.6.3.25) without a hitch. After the reboot I tried again to update my exisitng Quicktime Pro software as described in my original posting and got exactly the same error message.
If it happens that there is no software to download because I am already running the latest version, surely a message to that effect would appear and not the one saying “A connection to the QuickTime server could not be established. This computer may be having trouble accessing the Internet or the server may be offline”
Still seeking advice if possible
Cheers

The remote computer could not be found

Guys,
Im having this error message pop up when I launch a remoteapp from an external network through the rd web access page. On the deployment settings I have the gateway setting to "automatically detect rd gateway server settings". This always givves
me this error regardless of whether I edit the rdweb access application settings and add the defaultTSGateway : External FQDN.
If I switch the rd gateway settings in deployment proprties to "Use this rd gateway server setting" : external FQDN it works fine.
can someone tell me why? how does the automatically detect rd gateway server setting work and if it's even supposed to work if I am accessing apps externally?

Hi,
You should select Use these RD Gateway server settings in most cases. Automatically detect is for when the client PCs are domain-joined and you have specified the RD Gateway settings using group policy.

Remote Computer could not be found?

I have setup a Web Access RemoteApp server on Server 2008 R2 and it is no longer letting anyone connect to apps or use remote desktop from the outside. If I try to run any apps or try to RDP from the Web Access site it tries to launch but then I get a "The Remote Computer could not be found" error. It was working earlier today, I was able to launch applications from home but it now gives me that error.
Setup is as follows: All TS roles are installed on TSserver except the virtualization host since this is not a Hyper-V server. All the consoles show no issues, I have everything pointing to TSserver. I have an external site setup (remote.domain.com) and it is working. I can get to the site fine, apps populate fine and overall there are no issues there. If I go to the RemoteApp server internally I can launch applications and rdp without a problem. It's just externally that they're not working.
I admit I'm new to all these new TS roles and just started setting this all up. But I can't figure out why this was working earlier today and now is not. The only changes I made were a redirect for IIS (so that users only have to type in remote.domain.com instead of https://remote.domain.com/rdweb) and I installed a new application (though a co-worker said he started getting that error before I installed that program).
What should I be looking at to resolve this? The fact that it works internally and that I can get to the site externally makes me think it's some small setting I'm missing. With so many different management consoles to look through it's a little difficult to pinpoint what's wrong.

Hi,
Simple sharing of credentials between RD Gateway and RDS server can be enabled by doing the following :
On the RD Session Host server, open RemoteApp Manager. To open RemoteApp Manager, click Start, point to Administrative Tools, point to Remote Desktop Services, and then click RemoteApp Manager.
In the Actions pane of RemoteApp Manager, click RD Gateway Settings. (Or, in the Overview pane, next to RD Gateway Settings, click Change.)
Select the Use these RD Gateway server settings.
In the Logon box, select the Ask for password (NTLM).
Select the Use the same user credentials for RD Gateway and RD Session Host server check box.
Click OK to close the RemoteApp Deployment Settings dialog box.
If you want to enable web single sign on , please take a look at the following blog -

The remote name could not be resolved

We are running Office 365 Power BI (as a trial) and published our data through the data manager gateway service.
We are able to retrieve a list of shared tables / views through Power Query in Excel 2013 Professional Plus.
However, when clicking on edit on any table returned we get this error in the Power Query window:
DataSource.Error: OData: Request failed (NameResolutionFailure):
The remote name could not be resolved: 'SERVER-NAME.DOMAIN.local'
Details: https://POWERBISITE.hybridproxy.powerbi.com/ODataService/v1....
I have tried configuring the Data Manager Gateway service to run HTTP (at first) and HTTPS.
Could this be a port number issue? Or what else?
Appreciate any help, Thank you
Ian

Hi intrasight,
I gave the hosts thing a try.
I was getting 'unable to resolve' errors in attempting to use Power Query in a small stand-alone test domain (all computers are in the domain, and in this little LAN). So I edited
hosts in C:\Windows\System32\drivers\etc
I added this line:
192.168.0.4 mycomputer.ad.mydomain.com
mycomputer is the name of the computer running the Data Management Gateway, and
ad.mydomain.com is the name of the domain.
Now, I get
<textarea class="role-selectableText" cols="1" readonly="readonly" rows="1" style="width:659px;height:87px;" tabindex="-1">DataSource.Error: OData: Request failed: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS
secure channel. Details: https://mydomain.hybridproxy.powerbi.com/ODataService/v1.0/mydatasource</textarea>
Which tells me that hosts on the client is indeed now resolving the name/IP correctly, and Power Query is finding the DMG directly (rather than via the
hybridproxy.powerbi.com cloud service).
But that's terrible!
A) I shouldn't need to use hosts since
B) the hybridpproxy cloud service is finding the DMG on my database machine (because the Test Connection works OK)
C) but without hosts the client Power Query says that "The remote name could not be resolved"
DataSource.Error: OData: Request failed: The remote name could not be resolved: 'mycomputer.ad.mydomain.com'
Details:
https://mydomain.hybridproxy.powerbi.com/ODataService/v1.0/mydatasource
There's no way an actual production system should require editing
hosts on all client machines.
So to my mind, the original question is still outstanding.
How do I get Power Query to resolve the remote name?
Cheers, Donna

We are using the Azure server for our web services. Server is generating an error "Unable to connect to the remote server". What is this error means

We are using the Azure server for our web services. Server is generating an error "Unable to connect to the remote server". What is this error means

Hello,
Did you means that you use the Windows Azure Virtual Machine DNS name as the server name in the Reporting Server Web Services URL?
For example:
Report server:http://uebi.cloudapp.net/reportserver
Report manager:http://uebi.cloudapp.net/reports
If you want to connect to Report Manager on the virtual machine from a remote computer, you should create a virtual machine TCP Endpoint and open the port in the virtual machine’s firewall. By default, the report server listens for HTTP requests
on port 80.

An error occurred while connecting to the remote speaker. The network connection failed.

I can't get my itunes to connect to the remote speakers via airport express anymore - I did not change any settings - but did update iTunes to 10.2.2 and now things are not working and I get his message - "An error occurred while connecting to the remote speaker “Living Room”. The network connection failed."
Does anybody have a fix for this problem?
thanks

Same problem for me. Ever since I upgraded to 10.6.3 and iTunes 9.1, about once per week I'll get the error message when trying to get iTunes/Airtunes to connect to my older Airport Express (running firmware 6.3) "An error occurred while connecting to the remote speaker <insert speaker name here>. The network connection failed." (No error codes are given.)
Airport Utility sees the offending Airport Express just fine (and there's a green light on said AE).
Curiously, a newer AE-n, elsewhere in the house (running firmware 7.4.2) does NOT exhibit this problem.
Simply restarting the offending AE does NOT clear the problem. Restarting the main router - a Time Capsule DOES clear the problem. Alternatively, toggling off the Airtunes functionality on the offending AE, restarting it, then toggling Airtunes back on, and finally restarting it DOES clear the problem (as an alternate to restarting the router). No matter how the problem is cleared, it returns within a week. It's frustrating that the problem cannot be recreated immediately.
Probably not relevant, but the computer on which I'm running iTunes (a Mac Mini) is connected to my TC via ethernet, not wirelessly.
I've tried the suggestion of disabling ipv6. No effect.
I fear the only solution will be to scrap my older Airport Express and replace it with a newer n-model. But before I resign myself to the $100 fix, any more ideas?

ITunes - An Error occured while connecting to the remote speaker. (-15000)

I have been using airportexpress for the last 9 months with no problem. I used to use Windows Vista (32bit) to play itunes music and stream the music to the airportexpress which connects to my living room AV system.
Couple of days ago, I rebuilt my machine now running Win7 (64bit). Since then, I am not able to stream the audio to the airport express. Whenever I select the remote speakers, wait for about 30 secs and I get this error : An error occurred while connecting to the remote speakers "livingroom". An unknown error occured (-150000).
Does anyone experience this ? From the same machine, I am able to connect to the airport express using the airport utility. Wireless is working fine. I just not able to stream my music to it.
Regards
Moehadi

moehadi, Welcome to the discussion area!
This is typically caused by a firewall or Internet security software running on your PC. Please read the comments in "Error -3256 or -15000 when streaming to AirPort Express base stations using iTunes".
Also there is "iTunes 8: Unknown error -15000 when attempting to stream music to devices connected to AirPort Express with AirTunes".
