Laptop to desktop connection

I installed a linksys USB adapter on my desktop, and dowloaded the software. It seems to be working, since I can connect  to a neighbor's network. I can also connect to her network with my laptop. The problem is, I can't connect to my deasktop with my laptop. I have  searched for a solution, but had no luck.
In Network Connections, on my desktop, I have:
Verizon broadband connection thru WAN Miniport (PPPOE)
and ---Local Area Connection with limited or no connectivity thru the ethernet card. (if I disable this, I lose the Verizon connection)
and ---1394 Connection connected thru 1394 Net Adapter
and----Wireless Network Connection connected thru USB adapter
Can anybody help?
Thank, Rich

#1 The Westell 2200 is a modem combeo (modem and router-all-in-one), and it  is in router modem - unless an user behind it put it into bridge mode.
I point to
http://www.dslreports.com/faq/9265
To detect if the Westell 2200 is in bridge mode, do the following..
#1 Go to Start -> Run.
#2 Type in cmd and press enter.
#3 In the new window, type in ipconfig /all and press enter.
#4 With your web browser with the comptuter that  you can get online with, go to a web site that displays the public IP that you are coming from.
Such as http://www.whatsmyip.org/
#5 If any of the IP Address on your computer match (are the same), then the modem is in bridge mode.
If the Westell 2200 is in router mode: You could get a Wireles Access point, follow the directions on connecting it to the router, and get your computers on by wireless. Depending on which one you buy, it may also have at least two LAN ports.
Not buying any wireless access point?
#1 You could use ICS http://support.microsoft.com/kb/306126
#2 Or the computer with two NICs, could use bridge mode on the XP computer.

    Close ... before going for a specific Cisco app ... lets find out some details:
    Host we need more details:
    What is your server environment (Windows Server, or Mac OS X Server, or Linux)?
    What security is implemented in your environment - as what is restricted (RDP for all or specifc credentials on all machines? Are you part of local admin group to the server you wish to connect)?
    Does your environment Support CISCO IPSec connection? If so use Settings> VPN and IPSec tab to enter VPN details, if not then go with above suggestion. IF your restricted to RSA then either built in VPN settings or 3rd party app for RSA would suffice.
    Finally, there are many RDP applications out there I use "Mocha RDP Light" (free minimal ads when launched not when connecting).

  • Remote Desktop Connection from a Windows 8.1 laptop to a work PC using Windows 7

    Hi!
    I posted this question in the MS Community forums and they redirected me here... I searched the forums here but didn't find anything that helped with my problem. So here is my original question (posted originally here: http://answers.microsoft.com/en-us/windows/forum/windows8_1-networking/remote-desktop-connection-to-a-work-pc/5fa25045-de24-4a7c-9c8e-caf9ce17e444):
    For the past few weeks, I've been trying to set up a VPN connection to my work PC so I can work from home.
    Work PC runs on Windows 7 (I assume Pro, but I can't confirm at the moment).
    Home laptop runs on Windows 8.1 (the laptop came with Windows 8 already installed, so I assume it's the standard, or Home, edition. I manually upgraded to 8.1).
    Now, after many migraines and sleepless nights fiddling with settings, the VPN connection works. However, what prevents me from completing the connection is Remote Desktop Connection.
    Here's the error I get:
    "Remote Desktop can't find the computer "<computer name>". This might mean that "<computer name>" does not belong to the specified network. Verify the computer name and domain that you are trying to connect to."
    Note:
    - I DO have the correct computer name. I have a working connection to my work PC from my personal desktop PC (running XP), though I sometimes need to travel and a laptop is much more practical to carry around than a PC... ;)
    The VPN Connection Wizard never asked me to enter my destination PC username and password (so my work Windows credentials). Why?
    Any ideas as to why Remote Desktop doesn't want to connect?
    Any suggestions as to what I can try to fix the problem?
    Thank you for all the help!
    Julie

    Are you able to ping the remote system by name? It sounds as though you are connecting to VPN but are unable to resolve the names of the host network. A few things that I would think of:
    If the home system is not on a domain and the work system is, you may need to use the Fully Qualified Domain Name (FQDN). For example, instead of
    computer you would enter computer.domain.com.
    You may want to check if your VPN connection is configured as a default gateway, otherwise if your home and VPN network have the same IP address range you may be experiencing a conflict.
    See the instructions provided here.
    You also may want to check the DNS settings for the VPN connection to ensure that it is finding the DNS server for the remote network and thus is able to resolve the hostname.
    You may want to try connecting Remote Desktop via IP address to determine if the issue is with name resolution (DNS) or connectivity.

  • How to set up internet connection to laptop and desktop?

    I have a modem connected to an old lynksis router. I have my desktop hooked in port 2 on the router and my laptop in port one..
    The desktop's  network map shows it connected to a switch(my router) and the switch to my laptop and the laptop to the internet..
    Thus I have internet connection on my desktop
    but my problem is that the network map on the laptop shows it connected to the switch and the switch to my desktop
    thus no internet connection..
    how do I connect the laptop to the internet as well as share files? I'm confused after fiddling around for an hour.

    Hello,
    First, are you using Wifi for Internet on the MBP?
    System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.
    The interface that connects to the Internet should be dragged to the top of the list, Wifi on the MBP.
    In Shating on both, enable File Sharing, Screen Sharing, & Web Sharing on both.
    Then with the Ethernet cable between the two, find the IPs of both, or use Finder>Go>Connect to Server>Browse... see what shows up.

  • Remote Desktop Connection to Windows 8 PC from other computers crashing

    Hi all.
    Was hoping someone would be able to help me with an issue I'm having.
    I'm trying to get a LAN remote desktop connection established to my Windows 8 laptop. It's an HP ENVY 17t-2100 CTO 3D Edition Notebook PC. Note that I'm running Windows 8 Pro only - not 8.1 as HP haven't released 8.1 graphics drivers for this laptop and probably
    never will. The computer has a single user profile that has full administrator rights.
    I have followed numerous web tutorials on how to turn on Remote Desktop. I've gone into Advanced System Settings > System Properties > Remote > checked "Allow Remote connections to this computer". All seems ok to me. 
    The problem comes when I try to establish a connection. When the connection is made, it almost instantaneously crashes the session on the computer or device trying to connect. The RDP client on my Windows 7 laptop, Mac OSX or Mac running Windows 8.1 Pro just
    crashes, while the RDP iPhone or iPad app simply flickers for a few seconds then goes back to the main screen. Meanwhile, the HP ENVY loads the lock screen and displays a message saying XXX device is connected remotely and it won't let me log back in to kill
    the connection or do anything. I have to restart the computer from then to be able to use it again.
    I'm convinced there's not a problem with my local network as the HP ENVY can RDP into the Windows 7 laptop or Mac running Windows 8.1 without any problems. All computers are connected via Ethernet to a Linksys/Cisco wireless ADSL modem router which supports
    Gigabit. The iPhone and iPad of course connect to the wifi network from the Cisco/Linksys modem router
    I've also had a brief look at the RDP local connection logs. From what I can make out, they confirm that a user has successfully logged in, but they don't provide a crash log or a log of the user ever disconnecting, probably because I have to restart the computer
    to continue using it. Dead end there, it seems.
    The HP ENVY is connected to 3 external HP LED monitors. I've disconnected them and tried all devices with no luck. I've also played round with the RDP client settings to not mount drives or printers and the HP ENVY has no printers connected anyway, though I've
    done all I can to remove any printer drivers as I've read elsewhere that they are what could cause the problem, but I've had no luck. 
    If anyone can suggest anything more that I can try, I would be unbelievably grateful! I'm more than happy to provide screenshots or videos of what happens when I try connecting. I'm not sure what you experts would find immediately helpful so just ask away if
    you think I can provide anything.
    Thanks in advance!
    rugbyreff

    The first thing that I would try is to uncheck all of the boxes for local resources on computer running the RDP client. It is possible that a device, such as a printer or other redirected device, is causing the crash. You can also look under Event Viewer
    in the event logs of both systems and see if anything unusual appears when you attempt the remote connection.

    Hi Brandon
    Many thanks for your suggestions. There's nothing in the logs that I could find, like I said in the original post. I've also tried connecting with bare minimum settings on all devices (FYI the iPad and iPhone version don't support the use of printers) and
    this still hasn't helped.
    If you have any other ideas I'd be very glad to hear them!

  • Can 1 instance of Windows 8.1 ENTERPRISE host multiple Remote Desktop connections?

    I am shopping for the components for building a machine with fair, high-performance hardware. I have Windows 8.1 Professional. I wanted to know if either Windows 8.1 Professional or Windows 8.1 Enterprise can support multiple remote connections
    from users outside the local network. For example, my brother is based in San Diego, CA and has an underpowered laptop. Is there any way to make a remote connection over that much distance, from San Diego to Northern Virginia, from a RDP client running Windows
    8.1 Professional to a RDP "server" Windows 8.1 Professional/Enterprise machine, and run a modern, single- or multiplayer- game over smoothly that connection? At the very least, is it possible to run common
    apps (e.g. Microsoft Office 2013 IE 11, Adobe Acrobat XI) smoothly on a Windows 8.1 Pro RDP client connected to a Windows 8.1 RDP "server" located 2250+ miles away?
    Would upgrading my installation from Professional to Enterprise improve the responsiveness and display quality for my remote users?
    I know Windows Server R2 2012 has features specific for handling remote connections, but I am trying to keep a Windows 8.1 user experience. Still, if anyone can show some evidence that Windows Server 2012 R2 Remote Desktop Services (RDS)  improves display
    and responsiveness over long-distances for remote (RDS) connections, then I will shop for Windows Server 2012 R2 Standard instead. The huge drawback of Windows Server 2012 R2 Standard CALs is the enormous cost to enable 3-5
    remote connections for family, non-commercial use.
    Has anyone attempted to host long-distance remote access, non-commercially, for 3-5 connections? Has it worked well? What, in general, is required?
    T. Webster

    Hi,
    It depends on the quality of the network connection to run the software smoothly throuth RDP.  And I don't think the quality would be better if you upgrade to Windows 8.1 Enterprise.
    Windows 8.1 allow only one session of RDP, the Remote Desktop Server in Windows other than the Windows Server edition has a limitation to allow only one concurrent user per session by default, i.e. if someone remotely connects to the computer over RDP then
    whoever was logged in at that moment will be automatically logged off, even if that user is physically present at the computer. This is by design.
    Regarding more information about RDP, please take a look at the following articles:

  • Remote Desktop Connection keeps disconnecting

    I have BT Hub 3 (recently upgraded to Broadband Unlimited at the end of Jan 2015).
    Up until recently I was able to Remote Desktop into my work computer (via VPN tunnel) with no problems at all.
    Around March 6th, I began to experience problems with the Remote Desktop Connect (RDP), in that it now makes an initial connection and then disconnects (typically within a few seconds, occasionally after a couple of minutes).
    It will then cycle through a number of reconnection attempts, all with the same result, before it finally drops altogether with the message:
    'The Remote Desktop Services Session has ended. Connection to the remote computer was lost, possibly to network connectivity problems'.
    I have tried restoring both machines back to a date when i know the connection was working - no joy. I've also tried deleting an re-creating now VPN and RDP connections - no joy. I've researched online and tried various other things, but still have the same problem.
    I've tried connecting using a laptop (via my wirelss connection) with the same result. My manager has RDP'd in from his home machines and has had no problem at all.
    This leads me to consider whether the problem is with the router/BT Hub itself. I've tried the online diagnostic tools with no resolution to this problem.
    Has anyone else experienced the same problem?

    Oh well, I suppose that after more than 2 months of frustration with this issue, the BTCare Community is unable to help me.
    I can be fairly sure that it's not my machine as it's also happened using a laptop, plus I've even reset my PC right back to its original factory state just to sure that nothing had become corrupted.
    The network guys where I work have also looked at this and can find nothing at that end to cause this problem.
    I've even borrowed another BT Hub and tried it through that - same problem.
    So where does the answer lie? VPN issue? I've tried other VPN options - same problem. RDP problem? I've practically exhausted the list of suggested solutions that can be found by trawling the internet.
    I even upgraded the broadband cable to replace the cheap old thing that has been working perfectly well in terms of broadband, again, to eliminate this as a possibility. Now I'm stumped.
    To me, it looks like the problem lies between my router and the workplace network, i.e. a physical problem among the miles of lines connecting the two. Of course I don't want to shell out for a BT engineer to come out to investigate, so I thought that the combined wisdom of this community may have been able to help.
    Sadly not.

  • Remote Desktop Connection stopped working

    I made a change to my Verizon TV and Internet package, downgrading from Ultimate HD to Extreme HD and from 35/35 to 25/25.  This morning, when I ran a speed test it showed the new speed.  I went out for a few hours, and when I returned, my internet connection was not working at all.
    I called Verizon's support number and, after talking to two different people, one who wanted to swap out my router, and one who wanted to send a tech to check out my ONT, they finally figured out the problem was with their configuration, not any of the hardware in my house, and got me running again at the correct speed.
    During the trouble shooting process, they had me do multiple soft and hard reboots of my router, they remotely rebooted it, and had me push the recessed reset button once, restoring it to factory defaults.  This led to problems with my wireless devices, so I loaded a configuration file to the router that I had thankfully saved some time prior to this problem, and everything seemed to be working properly.
    Then, I tried to open a remote desktop connection from one of my machines to another one, both on my internal home network, a connection that had worked flawlessly up until now, and it would not work.  Moreover, trying to ping the "remote" machine from the one trying to initiate the connection gets no reply, but pings are replied to in the other direction.  And, both machines can see and access each other's shared folders and files, and both can see each other in the network map in the networking and sharing control panel app.
    I never made any configuration changes to either machine during the trouble shooting process, but to be sure, I used system restore on both machines and took them back to restore points made yesterday, when everything was working.
    I am at a loss to understand what has gone wrong, and would appreciate any constructive and helpful suggestions as to how to remedy this situation.
    ps
    I am running two different web servers on the target machine, and am running stunnel on it to provide secure nntp connections to a news client that doesn't have that capability built in, and none of these servers are available from other machines.  Nothing seems to be getting through to the target pc except windows network sharing!

    A perfect example. At least two game consoles. Any two (Two Xboxes, two Playstations, One Xbox and one Playstation).
    #3 If you have at least two special computers that support UPnP where you can not define the ports that they use....
    Do you only use one at time or are there times when at least two are on?
    #4 In the router go to Advanced -> IP Address Distribution Or to Advanced -> Private LAN
    #5 What is the Starting and Ending IP Address, that is listed in there?
    We have two Xboxes and a Logitech Revue.  I have Windows Media Sharing enabled on three computers, and am also running a beta of Logitech Media Server on one.   It is possible that there are times when two or more streaming clients are in operation, but that is a very rare occasion.  Two of the computers, the ones I mention in my original post, are on almost continuously.
    In Advanced -> Universal Plug and Play, both Allow Other Network Users to Control Wireless Broadband Router's Network Features and Enable Automatic Cleanup of Old Unused UPnP Services are checked, and WAN Connection Publication: is set to Publish Only the Main WAN Connection.
    In Advanced -> IP Address Distribution, under Dynamic IP Range it says192.168.1.2 - 192.168.1.254.  However, in Advanced -> IP Address Distribution -> Connection List I have set all the lease types to Static, because I was having problems using the Verizon web page to access my set top boxes, particularly the MRDVR.  The Static IP addresses for the computers, game consoles, Bluray player etc. are in the range 192.168.1.2 - 192.168.1.12, and the set top boxes are at 192.168.1.100 & 192.168.1.101.
    One thing I did not mention in my original post is that I have two unmanaged gigabit ethernet switches in my home network.  There are two computers, the ones I mention in my original post, and the Logitech Revue plugged into one switch.  That switch plugs into another switch which also has one pc, an Xbox, and a Bluray player plugged into it, and that switch then plugs into one of the ports on my Verizon supplied Actiontec MI424-WR Rev C, firmware version 4.0.16.1.56.0.10.14.4.  All of the other ethernet ports on the router are unused.  In addition, we have a laptop, a notebook, another Xbox, and a Wii that connect through the Actiontec's wireless.
    I don't know if media streaming is still working and I don't really care if it is because we use it so seldomly.  It never worked consistently or to our satisfaction.  When we want to watch or listen to media from one computer on another, we copy it over the network from shared folders.  We have a Homegroup, to which all of the computers belong.  If we want to watch or listen to media on one of the game consoles, we copy it to a flash drive.  The Bluray player is only connected to the network for firmware updates and for discs with network enabled content.
    This same setup was operating before the problem developed, and I can't figure out what has changed to create the problem.  The router configuration file that I am using is from June of 2011, and I'm pretty sure that everything was working fine then, and don't recall making any changes to the router's configuration since then.

  • Remote Desktop Connection using the WRT54GC

    I replaced a wired router with a Linksys WRT54GC wireless router. Connected to the wired router was a wireless router configured as an access point. I have 2 laptops and I successfully connected to the Internet from both. I was also able to connect to one of the laptops through the wireless access point using Remote Desktop Connection. The only difference between the configuration with the previous router and the Linksys is that the laptop with the Remote Desktop software (the host) was hard wired. Using the Linksys I can successfully access the Internet from both laptops. I can also get to the host computer over the LAN using Remote Desktop Connection. I CANNOT however access the host computer outside the LAN. I configured the router correctly using port forwarding and a 3389 port. I checked "enabled" and entered the IP Address of the host laptop (the one with the Remote Desktop Function). I disabled all security in the router. I have a dynamic address through dyndns.org and have setup the DNS portion of the router accordingly. Can you explain why I can no longer access my home computer remotely using Remote Desktop with the Linksys.

    Are you able to access Remote Desktop Connection directly connecting to the modem.

  • Remote Desktop Connection - Authentication error

    Hello,
    I wish to connect to my work PC from my laptop. The remote desktop connection was working fine till yesterday, but today i receive the following error when i try to connect - 
    "An authentication error has occurred. The Local Security Authority cannot be contacted. Remote Computer: <name>."
    I have Win 7 ultimate installed on my 32 bit system, and have tried solutions proposed in the other threads. I do not require a NLA check for connection, i have always used the remote desktop with this option unchecked. Could anyone help me with this please?
    Is this a error on my Laptop, or do i need to contact the network administrators for this?

    Hi!
    It could be as easy as you need to change your password on your domain accout.
    Are both computers connected to the same domian or is your work computer connected to a domain and your laptop connected to a workgroup?
    If your password has expired, this error can occur, so I would start to check that since it stoped working over night.

  • Remote Desktop Connection Solution, VPC NOT an option

    I downloaded Remote Desktop Connection yesterday B/C I wanted to be able to do work on my mac, I have virtual PC with WINXP but it was way to slooow.
    I do not want to play games, I play games on my compaq laptop that's in a full sized docking station.
    So I was looking and reading at this software (RDC) and it sounded like a viable option, My laptop has a 14" monitor but the iMac is a 17".
    so I downloaded it and set it up, BTW my connection is iMac to Laptop docking station I used a "Crossover Cable".
    Set the IP address and I have (Sorry to say) windows on my MAC for nuthing!
    It works great ALOT faster than VPC (since it does not have to emulate a Intel CPU).
    And the Laptop monitor goes to sleep after 1 minute so now I can have the best of both worlds!

    I'm not quite sure why you posted this.
    You marked your post as a question... but I can't find one.
    Do you have a question or was this somewhat of an "informational" post?

  • Remote Desktop Connection with WRT54G from Novice

    Well, I’m usually pretty good at using Google and forums to eventually figure out how to fix my problem but this one absolutely has me stumped and I’m hoping someone out there has an answer for me. For the record, I have probably a beginner/intermediate knowledge of computers so if you know the answer to my problem, try to explain it simply! ****TO ANYONE WHO TAKES THE TIME TO READ THIS THING AND CAN OFFER SOME ADVICE-THANK YOU!!!!***
    THE PROBLEM
    I would like to be able to use Remote Desktop to log into either of my home computers from basically any computer on the internet.
    THE SETUP
    I have two computers, whose names are LAPTOP and DESKTOP that are both running Windows Vista Ultimate. Both of the computers are connected to a Linksys WRt54G Router ; one wired, the other wirelessly. The Linksys router is then connected to a Westell DSL Modem that connects to AT&T’s internet service.
    SETTINGS
    My DSL service only provides me with a dynamic IP address so I signed up with no-ip.com. Through that site, I bought a domain name and downloaded their small program that runs in the background of my desktop computer. The program checks what my IP address is every couple of seconds and if it changes, it notifies their server so that anyone who types in my domain name is directed to the new IP address.
    ROUTER (Firmware 4.20.6)
    Basic Setup Page: The Router Name is just the model number, the Server Name is my DSL provider and the Domain Name is the name I chose and registered with No-IP.com. (www.mydomainname.com, for example.) DHCP Server is ENABLED. DDNS Service is DISABLED. Under Advanced  Routing, it is set in GATEWAY mode.
    Security Page: Firewall Protection is ENABLED. Block Anonymous Internet Requests is NOT checked. Filter Multicast, Filter Internet NAT Redirection and Filter IDENT ARE checked.
    Applications and Gaming Page: I chose two port numbers, one for each computer that I want to connect to. On the first line, I have Application: RDP, Port Range: 49200 to 49200, Protocol: Both, IP Address (The IP address of the computer I want to connect to) and the Enable box IS checked. [I did the same thing with the second line for the other computer, but with a different port number and that computer’s IP address)
    Administration Page: Access Server is HTTP, Wireless Access Web is ENABLED, Remote Management is ENABLED through Port 8080, and UPnP is ENABLED.
    WINDOWS VISTA SETTINGS
    First, I went to the Remote Desktop Settings of the target computer and ENABLED Remote Desktop Connection and allowed computers running any version of Windows. I also confirmed that the box labeled “Allow This Computer To Be Controlled Remotely” WAS checked. I then made sure that I had a user name, it had a password associated and that it had Administrator priveledges. I went back to the Remote Connections screen and added the user name as being allowed to connect. (I think this is redundant since it’s both the owner of the computer and has Administrator Status.)
    Next, per Randomly Googled Internet Advice, I went into the registry and changed the port number that Remote Desktop listens for incoming connections to Port 49200 to match the router settings. [Registry Entry that I modified was: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp]
    Finally, I went to the Windows Firewall and Added (opened) port 49200 for use as a Remote Connection. I kept the protocol as TCP and confirmed the scope was set for Any Computer.
    CURRENT STATUS
    If I go to Explorer and enter my IP address with a colon and the specify port 8080, I can get the login screen for the router. Same thing happens if I just enter my domain name and port 8080. However, if I switch the 8080 port and use one of the ports I chose (49200), it cannot connect, either using the Public IP address or the domain name. (I’m trying to connect using a wireless card and not connected to my local network so I know it’s the same as if I was anywhere else.)
    I’m not sure why it won’t let me connect; it feels like the router will not allow the connection to pass through it to the port I’m asking it to forward to. I’m guessing someone out there who took the time to read it is shaking their head at all the information I provided and knows the one dumb thing I missed!
    Thanks again!

    I'm attempting to do the same thing with my home network. the only differences are that i have cable internet from comcast and i'm running vista business. my router is the wrt54gs. i'm assuming that the web page is similar for adjustmants. To be honest i cannot figure out how to do a remote destop too. so i went to www.logmein.com and installed the program. once installed to to every computer you want to have access too and log into the website. then click on the add computer icom. full control app sharing etc... even better when you connect you have the option to deactivate the local host mouse and screen to prevent anyone seeing what your doing.
    If you resolve the router issue would you let me know. plz thanks
