Access by IP address but not URL?

One laptop on our network exhibits strange behaviour occasionally. It will be working fine, then will suddenly lose the ability to access a website or any other server by its domain name.
Using Network Utility to lookup the address, the DNS responds with all the correct information. And in Terminal, nslookup and dig both correctly resolve the domain name to the IP address.
However no other application seems able to use this information. Safari, Mail, Software Update all fail to connect to the requested servers.
Mac OS X 10.6.8, MacBook Pro 2.66 Ghz Intel Core i7
Hope someone can assist
Cheers

It's nice of you to reply. But the existing DNS server (which by the way is on our LAN) is giving the proper answers.
This only happens with *one* computer on the network, and then only sometimes. But when the computer is exhibiting this problem, dig and nslookup both resolve IP addresses correctly - but apps like Safari and Mail seem unable to use this information.
The only way I have found of sorting this is to restart the client computer, at which point it works fine.
Logging out and back in as a different user has no effect.
Any ideas?
Cheers
James

  • After installing Mountain Lion, why is there Yahoo access for one user but not another?--both are administrators.

    After installing Mountain Lion, why is there Yahoo access for one user but not another?--both are administrators.

    We've had several instances where we have had to run chkdsk on arrays with over 1m files. Average completion time is approximately 72 hours. The maximum downtime window they have available is the 64 hour weekend window. File sizes and number of files were
    much smaller then than they are now.
    The idea, in theory, was to use VHDs to compartmentalize the data into smaller volumes which could be more easily managed. It would also improve performance when transferring these compartments of data as they would use sequential read/write rather than
    fragmented/random. This idea was never fleshed out in entirety, they don't split data up into little containers, but simply into big ones per project. Hence the 11m files in one container that I am currently trying to diagnose.
    Some other important facts: The VHD in question is mounted in B:/project/ as this server also allows remote workers to log in, but they are restricted to see only data in E:. Disks A-D are hidden via group policy.
    Update: icacls is failing on a large number of files within this dataset. I counted the path characters to ensure it wasn't the 255 character limit I was encountering and verified that the paths being blocked are only about 150 characters long. Once it finishes,
    I'll have to try taking ownership and then re-running it. At this point I still have no idea how long to expect. I'm running out of time as the environment will be in use again at 9AM tomorrow morning.

  • Why I get double phone numbers and addresses but not notes within a contact when I sync iphone 4S with Outlook 2007?

    I get double phone numbers, double addresses, but not double notes, when I sync iPhne 4S with Outlook 2007. How can I prevent it from happening?

    Yes, I removed iCloud add-on from Outlook; and uninstalled iCloud.  I then re-installed, and sync would not work (no tab for sync in Outlook either). There was no improvement.
    However, since reading your post, I have just tried signing out of icloud control panel and signing in again....and now all si working as it should.  Weird!!
    Thanks for your assistance.

    This was EXACTLY what I needed about the purchases I made from my device. However, is there a way to re-download other ones you've made from a computer? Because I realized some of them were not just purchased from my device.
    This is a picture of what it looks like now:
    http://tinypic.com/r/107quxu/7
    As you can see, the stuff circled in red doesn't give me an option to download from Cloud Beta because it already says "downloaded".
    any way to get around that?

  • E-print works on some e-mail address, but not others?

    HP Officejet Pro8600
    Windows 7 Ultimate
    error: "550 5.7.1 Command rejected"
    I am able to send and print e-mail print jobs from @hotmail.com and @live.com addresses, but not from @q.com (a Century Link primary domain for customers, not a corporate account). I have set up "Anyone can send ePrint jobs to this printer." These failed print jobs never appear in the ePrint Center listing of Recent Print Jobs. I have tried sending via Outlook 2010 and via the Century Link web based e-mail application -- they both return to me as bounced messages. What's going on here?

  • When i click on itunes on my ipad2 i get the error ..'cannot connect to itunes store'...i'm able to access podcasts and itunesU but not itunes store. This is very strange as i can access app's store

    when i click on itunes on my ipad2 i get the error ..'cannot connect to itunes'...I'm able to access podcasts and itunes U but not itunes store..my apps store and safari are also working perfectly but don't know whats the issue with i tunes store...i use an airtel broadband connection through a wifi router..pls help

    I was having this problem. The settings on my wireless router was set to hide my IP address so it wouldn't connect. When I changed that, I connected no problem. While this is annoying since I don't want my IP address to be out there, I just switch my router when I need to connect to the App/iTunes Store. Hope this helps. It worked for me.

  • Want to access iTunes music store but not in a 'valid' country

    Hi, I'd really appreciate any help anyone can offer. I want to be able to buy music and videos for my new iPod and I have registered online. When I go to buy something with my credit card from the iTunes store, apparently you have to have an address for your credit card and a list of country's excluding Australia comes up. The problem is there is only about a dozen countries on the list and mine is not one of them so I can't pay by credit card. What can I do???

    I really wish I was informed when I bought my ipod, that Itunes music store is not available in NZ and we don’t know when or IF it is going to be. Am feeling totally ripped off as one of the reasons I bought my ipod on Sunday was so I could download Audio books off itunes for when I am travelling. Now I go online and find out that I cant even download a measly single let alone a audio book.
    Was feeling so excited about having my ipod and now just feel ripped off and extremely disappointed with Apple and the Apple salespeople. You are told how great itunes is and how you can download video, songs, books etc (when you are buying your Ipod) then once you have paid you $579+ (just for the ipod, let alone another $300 on accessories and warranty) you find out you can't download anything from itunes. Am pretty disgusted really! I researched my purchase, was going to go for a CREATIVE merely so could access NZ download sites, but was talked out of it by the sales person who showed me itunes and how great it is and I do think the IPOD itself is fantastic but wish I had of bought that CREATIVE so at least then I could have downloaded songs; books etc immediately. Bad Form from Apple, particularly given the amount of money I just spent :(((

  • ITunes accounts can be accessed under one User but not a second User.

    Hi
    I'm having problems setting up iTunes on a new PC I've recently purchased. On my old PC - (Vista), myself (David) and my wife (Chris) had different Windows Users accounts, both with separate iTunes accounts which we could access with no problems.
    On my new Pc (Windows 7) I have downloaded iTunes and can access my iTunes account with my ID and password when the PC is logged in as 'David' as the User, as can my wife BUT when the PC the PC is logged in as my wife as the  User 'Chris' neither of us can access our iTunes account with our relative ID and passwords. We get the message.. "The iTunes Store is temporarily unavailable. Please try again later.".
    I have seen this sentence on Google and on various forums including this one but cannot find a solution which fits my problem which is our iTunes accounts can be accessed when the PC is logged in under one User but not a second User.
    Has anyone have ideas to attempt to resolve this issue?
    Thank you

    Reset the device:
    Press and hold the Sleep/Wake button and the Home button together for at least ten seconds, until the Apple logo appears.
    If that doesn't help, tap Settings > General > Reset > Reset All Settings
    If that didn't help, tap Settings > General > Reset > Reset Network Settings
    You will have to re enter the Wi-Fi password.
    If that doesn't help, try here >  iOS: Troubleshooting Wi-Fi networks and connections
    No data is lost due to a reset.

  • I can access exchange from internal ip address address but not external

    Hi there, been trying to set up my iphone to collect my email from my exchange server 2003 sp 2 and have been having huge problems.
    My IT guys we use have done everything they can so far and we tried setting up the email by connecting through my wireless network and on my intenal ip address to by pass my westell router and it works.
    Now as soon as we try this outside and turn off the wi-fi and change ip adress to external, basically my OWA web address the verification fails.
    We use an actual number like 000.00.00.000 rather than this webmail.mycompany.com etc I have read about. Sorry not very good at this sort of thing so sorry if I sound like a novice.
    Any help appreciated.

    In order to connect to an Exchange server from internal and external, you must connect via a URL and not a specific IP address.
    The reason for this is that internal IP addresses (10.10.x.x, 192.168.x.x) are different than external IP addresses, therefore you will not be able to connect externally as you reported.
    If you connect to Exchange using a URL (example: http://mail.domain.com, the URL is mapped to both the internal IP and external IP - and thus the iPhone will work everywhere. Internal mapping is done in the server's DNS records. External mapping is done by contacting your internet provider and adding an A record. (You will also need a firewall mapping from external to internal with port 80 open for incoming traffic.)
    When you set it up as above, it works like a champ on Edge/3G and WiFi whether your in the office or outside.
