Page Cannot be Displayed - IBM Access Connections

I recently purchased an IBM ThinkPad T42.  During the day this machine is attached to a docking station and used at work.  At the end of the day I undock the computer and take it home with me.  I am attempting to use IBM Access Connections to have the computer automatically switch between my home and work network settings.  I set up a “Work” location profile that uses the NIC card and applied the appropriate proxy settings.  I also set up a “Home” location profile that connects to my home wireless network and applied the appropriate proxy settings (none).  The “Work” location profile works fine.  The “Home” location profile does not.  When I turn the computer on at home it automatically switches to the “Home” location profile and connects to my wireless network.  I am then able to successfully ping the router and various web sites.  However, when I attempt to view a website in IE I receive a “Page Cannot be Displayed” error.  Does anyone know what may be causing this?

Thanks in advance for your help.

If you are able to i would try to download another web browser and see if the same thing happens. If it doesn't, then maybe reseting the IE settings will fix this. If the same thing does happen with another browser then I would guess that DNS is not being read properly. If you can successfuly ping a web site (i am guessing by the name, www.abc.com) through a command prompt then DNS should work. however if the browser got hijacked perhaps it is blocking access to sites.

Also check to see if you are using a hosts file. If so maybe something in the hosts file is confilcting with home connection but for work connection it may be needed.

msidnam,

Thanks for the quick response.  I will try another browser tonight.  Yes, I am able to to ping websites by name, so DNS should be working.  The only entry in my host file is 127.0.0.1.  I have scanned the computer for spyware and found nothing.  Also IE works fine with the work location profile, so I don't think this is a hijack issue.

When you are home do you log in differently? I know for our office when the users are at home or at a client we have them log into "computer name (this computer)"

Maybe there is a program installed that has IE verify something at the office that is not available at home and so IE says "nope i can't verify my connection so i won't go to the web" I am throwing out some things but i have seen strange things happen. One time i forgot i had Zone alarm installed and couldnt for the life of me figure out why my messanger program would not work. After about a month i checked the zone alarm settings and realised it was blocking access. Sorry for the rambling.

Let us know what happens if you install a new browser. :)

msidnam,
I have been logging in the same I way I do at work.  I will try logging in to "computer name" and see what happens.  I will also investigate other programs.

visualcoat,
I will try your suggestion also.

Unfortunalely I will not be able to try these things until I get home tonight.  I will post more then.  Thanks.

After further investigation I discovered that it is Microsoft Firewall Client that is causing me problems.  I thought that I had disabled this on the home profile, but apparently not.  I guess it is still looking for the ISA server at work.  After completely removing the firewall client my home connection works fine.  Does anyone know of a way to disable or bypass the firewall client when using the home profile?

I am not familiar with ISA servers. But I do not think there is a way to tell the firewall what profile you are using. Maybe it could be changed depending on what user is logged in?

msidnam,

Thanks for all of your help on this.  I will continue to investigate the ISA thing and maybe post another question when I have more time.

Thanks again!

Have been fighting similar problem with X40. I believe you are able to ping the router but not access the web because the router has failed to assign the correct IP address. Assuming your router is set up for the 192.168.x.x DHCP range, try double clicking the Windows wireless connection icon (not access connections), click on the support tab and see if the IP range looks right. This seems to happen when resuming from standby OR, for some reason, when undocking the Thinkpad. The quickest fix is going into Access Connections and force a reconnect, which should result in reassignment of a "good" IP address.

For more info, try the search string "unknown IP address" or "mystery IP address" here in Experts Exchange. I've found helpful info.

Also, make sure you are using the latest version of access connections. The "after standby" thing seems to have gone away using latest Access Connections, but undocking seems to be creating anomolies on OTHER wireless devices (not the Thinkpad itself)

Incidentally, this is my first post here so apologies in advance if I have violated any protocols. This is not intendes as an anwer, just a comment.
