Precision M65 random network problem

My M65 with Vista Business Edition (same issue with XP prior to upgrading) will randomly loose all or part of its network connection.  The strange thing is that my MSN and Skype both are showing good connection but web and email looses connection.  I have even been on a Skype call when my browser looses connection with all web pages and Outlook can't connect to the email server.  I have searched high and low and can't find a reason. 
 
The Network andSharing Center is reporting that all is OK, but if I click to Diagnose and repair it then finds that it can't connect to www.microsoft.com and recomends to restart the NIC, which never helps.  The same happens on WiFi, which is live at the same time.
 
The only way to restore connection is to reboot, which is obviously a pain.  This happens once or twice a day at random hours.  So far I have not experienced this when I am at home on my WiFi, but then at the office our router has been replace twice with no improvement.
 
Anybody come accross this before?

    Sounds like your DNS server is not working as it should for some reason.  Start, Run, cmd.exe, OK to bring up a new black cmd screen.  Type (with an Enter after each line):
     
    ipconfig /all
     
    (Note the DNS address.  Put that in your next reply.)
     
    nslookup microsoft.com
     
    (You should get something like this:

    Non-authoritative answer:
    Name:    microsoft.com
    Addresses:  207.46.232.182, 207.46.197.32
     
    Do you?)
     
    exit
     
    (CMD window closes.)

    Do
     
     
    Oddly enough it comes back with different answers:
     

    Non-authoritative answer:
    Name:    lb1.www.ms.akadns.net
    Addresses:  207.46.192.254, 207.46.193.254, 207.46.19.190, 207.46.19.254
    Aliases:  www.microsoft.com, toggle.www.ms.akadns.net
              g.www.ms.akadns.net

    Non-authoritative answer:
    Name:    microsoft.com
    Addresses:  207.46.232.182, 207.46.197.32
    Also check your hosts file: 
     
     
    notepad \windows\system32\drivers\etc\hosts
     
    Delete any lines you find below the line that says
    127.0.0.1 localhost
     
    Then close and Save.
     
    Open IE then put in
     
    207.46.192.254
     
    instead of www.microsoft.com.  Does that work?

    Just noticed you said ping and not reach.  Doesn't matter very much if you can't ping them.  Lot's of sites don't respond to pings.

    Iipconfig /all gives these two DNS servers:
    204.57.114.70 & 204.57.112.2
     
    nslookup microsoft.com gives:
     
    Non-authoritative answer:
    Name:    microsoft.com
    Addresses:  207.46.232.182, 207.46.197.32
     
    But then right now my connection is fine.  I'll try this when it is not.
     
    I can ping microsoft.com, but not www.microsoft.com
     
    Thanks so far

    I will have to try these things when the connection goes down, I guess, as I see the same as you do now.  My host file only had these two lines:
     
    127.0.0.1       localhost
    ::1             localhost
     
    I tried to save it, but it did not allow me (Vista), but I don't think it matters right now.
     
    I have placed a call with the "owner" of the DNS server to see if they have any clues.  Are there any global DNS server I can use to see if that sorts problem?

    The second line is OK.  It's the new IP version 6 line which isn't really used much yet.
     
    Try these from Dell:
     
    143.166.83.13
    143.166.224.3
     
    You can test them this way:
     
    nslookup
     
    server 143.166.83.13
     

     dell.com
     
    (Answer should be similar to this:
    Server:  ns5.us.dell.com
    Address:  143.166.83.13
    Name:    dell.com
    Addresses:  143.166.224.244, 143.166.83.38
    )
