VPN via NetExtender OK but can't connect to server. Help!

Hi All,
I am a new Mac convert and I have completely fallen in love with Mac.  I just purchased a MacBook Air and I am running OS X 10.7.2.
I have setup my Mac to access shared network drives at the office while physically in the office.  I also have been able to successfully remote into a small workstation I have for running some funky billing software with no problems.  All while phyiscally in my office.
Now, I have installed Sonicwall NetExtender SSL-VPN client ver. 5.5.707.  I can connect to my office network OK with NetExtender.  However, I cannot access the shared drives or remote into my small workstation via NetExtender.    What am I missing here?
Again, when I am local and in my office, I can use my Mac and connect to everything in my office no problem.  But I cannot do so when traveling and trying to connect via Sonicwall NetExtender.  Can anyone help?
Thanks in advance.

Emilio,
Welcome to the Discussions.
Do you have an account set up with your ISP? If so, you might be able to use the SMTP provided by your ISP, instead of the smtp.mac.com.
However, if your ISP is merely blocking the use of Port 25 (as many now do), try changing the Port to 587. See:
http://docs.info.apple.com/article.html?artnum=166743
More info, please.

  • I can VPN into my work but can't connect to any devices inside that network

    I authenticate fine and get an address but I cant connect to any devices inside my work.  I am connecting to Cisco Lan controllers, routers, and switches.
    I thought it was a routing problem but I can connect with my iphone and open the webpage for my lan controllers and I even tested it on a pc laptop with Windows XP and it works fine.  I have a 2012 Macbook pro.  I prefer to use my Macbook all the time.  I haven't used my Windows laptop until today since I got the Mac.  Do you think I have the V-Word?

    Please read this whole message before doing anything. This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it. The purpose of this test is to determine whether your problem is caused by third-party system modifications that load automatically at startup or login. Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows: 
    Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
    When you see the gray Apple logo, release the shift key.
    If you are prompted to log in, type your password, and then hold down the shift key again as you click  Log in.
     *Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs. The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

  • VPN to a Windows Network - can't connect to server using RDC

    I'm trying to connect to my office's windows network.
    I can connect using Cisco VPN but can't when I try to Connect to Server when specifying AFP or SMB as the path. I was told SMB is not supported and that I should just be able to use RDC once the VPN is established. RDC however is not connecting for me either. Any suggestions are greatly appreciated. Thnx

    Check your System Preference settings under sharing,
    if your firewall is on it may cause issues. Turn it
    off and see if that solves it for you. If not make
    sure you're using the latest client (4.9).
    Hi. Problem occurs with and without firewall on. I'm using Cisco VPN 4.9 too. I've been able to use RDC before which is weird. I'm not sure, but ever since the last Apple Security Update last week...I have been having this problem. But I'm not ruling out anything the IT dept. may be doing. :\

  • Airport Express connects (green light), but can't connect to server

    Hi!
    I set up my airport express (and it took me a while) and it worked great for 2 years!
    I recently moved and tried to set it up again, and it will not work. I even returned the settings to the factory settings and still and having great difficulty in connecting. I just set up comcast internet, and plugged the AE into the modem via ethernet. I entered in the proper info (IP, subnet mask, router #, DNS, and domain) manually, as the default settings wouldn't work. I recieved a GREEN light on the AE and am able to access it via Airport Utility. However, I am unable to access the internet with safari or firefox (they can't find the server). I can access the internet with just the ethernet plugged into the macbook.
    I have tried resetting the AE many times, and have done MULTIPLE power cycles, and still cannot fix the problem. Can someone help me?

    What Comcast modem (brand and model) do you have?  Was it connected to any other device (perhaps the computer you used to set it up) before you tried to connect the AirPort Express?  If so, you'll probably have to reset the modem (perhaps by cycling power) to convince it to connect to a "new" device.
    I'd avoid those manual settings.  You shouldn't need them and they can cause other problems.

  • Network library printer can't 'connect to server', help?!

    I recently upgraded to Yosemite and tried printing as usual from the cloud printing at my library.
    Usually it holds for authentication and I enter my university username and password.
    However, this time it just says 'cannot connect to server' and then pauses the print job.
    I reinstalled the printer but nothing changed.
    Can anyone help?!

    Hello there, LydiaMayPorter.
    Great job so far in troubleshooting the issue on your own. The following Knowledge Base article offers a very thorough resource with additional steps for troubleshooting printing issues in Mac OS X Yosemite:

    Additional things to try.
    Try this first. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
    Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
    Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
    Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

  • I have an iMac running OS X 10.8.3 and have connected an Epson Workforce 2540 printed that is allegedly Airprint enabled. I can connect and print with a USB cable but can't connect via Airprint. My colleague running 10.7 can. Is this a feature of 10.8?

    I have an iMac running OS X 10.8.3 and have connected an Epson Workforce 2540 printed that is allegedly Airprint enabled. I can connect and print with a USB cable but can't connect via Airprint. My colleague running 10.7 can. Is this a feature of 10.8? Any ideas for a fix?

    iOS devices use AirPrint to connect to a supported printer. OS X will use Bonjour to locate and connect to the same printer.
    With the Epson connected to your wireless router, when you open Print & Scan and click the plus button to add, does the Epson appear in a small box with a heading of Nearby Printers?
    If not and a window appears showing Default, Fax, IP and Windows in the toolbar, do you see the Epson with the Default view selected?

    We have an ipod touch, 3rd generation, 8GB. we lost the unlock code. we now try recovery via itunes, but can't connect to the ipod software update server. any suggestions?

    Update Server
    Try:
    - Powering off and then back on your router.
    - iTunes for Windows: iTunes cannot contact the iPhone, iPad, or iPod software update server
    - Change the DNS to either Google's or Open DNS servers
    Public DNS — Google Developers
    OpenDNS IP Addresses
    - Try on another computer/network
    - Wait if it is an Apple problem

  • ITunes (and Airfoil) can see Airport Express but can't connect in Windows XP (error -15000) - firewall problems?

    I am using Windows XP Professional 2002 w/ SP3 on a Dell Latitude E4300 laptop wirelessly connecting to my Airport Express 802.11n (firmware 7.5.2).
    I can see my Airport Express in iTunes 10.4.1 and can select it via the Airplay button. iTunes even detects whether or not a speaker is connected to the Airport Express. But when iTunes tries to connect, it comes back after a while saying "An error occurred while connecting to the Airplay device xxx. An unknown error occurred (error -15000)."
    A similar problem happens with Airfoil from Rogue Amoeba that I use to stream music from other apps such as VideoLAN to Airport Express on the same laptop. I can see that my Airport Express is available but when Airfoil tries to connect, it comes back saying "It appears that a firewall on this computer is preventing Airfoil from connecting to xxx Airport Express. Please check your firewall settings and try again."
    I've set both Airplay and iTunes as exception programs in my Windows Firewall setting, and even added TCP ports 5000 to 5005 and UDP ports 6000 to 6005 to the exceptions as recommended by Airfoil. I've also disabled Symantec Endpoint Protection that Ihave installed. The only thing I can't disable is McAfee Endpoint Encryption, since I also use the laptop at work and I don't have permission to disableMcAfee.  I use this laptop to connect wirelessly with other devices such as HP wireless printers, NAS drives and other laptops on my home network and have never had any issues, so i think that this issue is specific to the Airplay software being blocked by some firewall (I am assuming Airfoil also uses Airplay).
    I've tried this on different wireless networks and I have the same issue with Windows XP on my Dell Latitude E4300. I've also set up the network with no security, but the problem doesn't go away.
    I also tried downgrading iTunes to 10.3.1 but won't work. I think it's an Airplay issue, not a specific iTunes issue, since I'm facing the problem with Airfoil as well.
    How do I trace what is going on that is preventing iTunes and Airfoil from streaming to the AirportExpress within Windows XP?
    I also have another Dell Inspiron laptop on the same network running on Windows Vista, and have no problems streaming music from iTunes or Airfoil to the Airport Express on the same network, even when the network is WPA-2 Personal (TKIP+AES) protected (I've seen other postings where WPA has been an issue, WEP has not, but in my case, this is not an issue). Ditto with my iPad2.
    Thanks for your help!

    I have the same problem with Windows 7 64bit. ITune can see AE and stream Music well. Airfoil, TuneBlade (airplay soft) can also see AE but can't connect and stream music. I ' ve already tried to setup firewall Exception list, even turning off firewall off both windows and antivirus but still got the same problem with the message 'Airfoil was unable to connect to the remote speaker " ... 's Airport Express". Please check the firewall on the computer where " ...'s Airport Express" is running and try again'. Any help would be appreciated !.

    Help, please.

    Try clearing Safari's cache : Settings > Safari > Clear Cache (and Clear History)
    If that doesn't work then try closing Safari completely and then re-open it : from the home screen (i.e. not with Safari 'open' on-screen) double-click the home button to bring up the taskbar, then press and hold any of the apps on the taskbar for a couple of seconds or so until they start shaking, then press the '-' in the top left of the Safari app to close it, and touch any part of the screen above the taskbar so as to stop the shaking and close the taskbar.
    A third option is a reset : press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.

  • Computer is connected to network but can't connect to internet (Safari and Chrome), e-mail, App Store, ect.

    My Macbook is connected to Wi-fi (four bars) but can't connect to the internet or any other services that requires internet. Other devices in my house have easily connected to the internet but every time I open Chrome it says: "This webpage is not available". What do I do?

    Restart your internet modem and router and your Mac then try Safari etc.
    If that doesn't help, try this DNS server ..
    Open System Preferences > Network > Advanced > DNS
    Click + and type:

    Click + again and do the same.
    208.67.220.220

    Try a browser.
    if that doesn't help, check the firewall.  System Preferences > Security & Privacy > Firewall > Firewall Options

  • Connected to WiFi but can't connect to internet

    Hi all,
    My iPod touch is connected to my secure home wifi network, the wifi icon is displayed with 4 bars, and I can use some wireless apps like Remote for itunes. I can connect to the internet on my laptop, but not my iPod. When I try to use safari/itunes/app store I'm told the device is not connected to the internet. Up to today everything had been working fine, and I haven't changed any settings. MAC filtering on the router is not enabled, I've tried turning wifi off and on again on the ipod, resetting all settings and turning the ipod on and off again but still no connection.
    Any help would be much appreciated!

    Reset the router, did the trick. Had the wrong IP address ie. 169.xx... rather than 192.xx.. Resetting the wireless router remedied this.
