Choose one or the other Dilemma!

Windows XP Pro.

I have a Wireless Connection between my Desktop and Laptop.
The Laptop connects wirelessly to the Desktop and uses its 56k Dial-Up Internet connection through ICS.

Lately:

I can do 1 of 2 things but I can't do both.

After running the Network Wizard,
If I manage to view web pages on my laptop, then suddenly web pages don't show up anymore on my desktop once I restart the computer. At the same time, a message box shows up saying "The TCP/IP network transport is not installed" - (might be a red herring).

On the other hand, When I restore my Desktop to an earlier time, I manage to use the Internet on the desktop but the web pages won't show up on the laptop.

What's going on?

 

Do the following and post the contents of the resulting text files. Specify which of the two problem conditions was in effect when you ran the command and which PC generated what set of values.

start~run~cmd
ipconfig /all > c:\config.txt

Then do what is needed to cause the other condition and do the same thing again. Just make sure we can clearly know which PC and what condition.

The resulting text files may point to the problem and a cure or they may simply show that one piece of your setup is perfectly fine and we have to look elsewhere.

Please do not mask any of the IP address/subnetmask/gateway/etc. values. Need to see exactly what they are.

 

ok, At the time of performing the above operation,
The Desktop was connected to the net and was displaying pages fine.

The Laptop was networked to the Desktop fine but could not view web pages thru IE. You get the familiar "page could not be found" message.

In addition, there is no config.txt on the laptop so I copied the results from Dos Prompt.

On Both machines, I went to the Wireless Connection Properties ~ Genral Tab ~ Internet Protocol Properties ~ and both have "Obtain an IP address Automatically" checked.
In the past I have already tried setting the desktop to 192.168.0.1 and the Laptop to .2 but still hasn't worked.

Anyway

Here are the results.

What do you suggest?

 

Well - the reason you are having trouble is evident from what you posted. The underlying cause - not yet but we'll get there.

First item (and to save you some typing down the road), the config.txt file is created by the ipconfig /all > c:\config.txt command. The > symbol is a redirector that tells the system to send output to that file rather than the default location - the screen. Any file name should have worked; I just use config.txt to keep life simple. You can direct any output from a DOS command to a file using this trick. Nothing should show on the screen since it is writing it to a file for you.

Next item and using the info from the laptop but you have a network card (NIC) on the desktop doing the same thing - I've removed the pieces that aren't important here

Code:

Description . . . . . . . . . . . : Intel(R) PRO/Wireless LAN 2100 3B Mini PCI Adapter
Physical Address. . . . . . . . . : 00-04-23-49-33-0C
Dhcp Enabled. . . . . . . . . . . : Yes
Autoconfiguration Enabled . . . . : Yes
Autoconfiguration IP Address. . . : 169.254.217.41
Subnet Mask . . . . . . . . . . . : 255.255.0.0
Default Gateway . . . . . . . . . :

- with DHCP & Autoconfiguration both enabled, you are telling the NIC to get setup values from the nearest DHCP server. In your case, ICS on the desktop should be providing that service.

- the IP address and subnet mask you are getting is autogenerated by the laptop because it couldn't find any source for values so XP plugged in an APIPA IP and subnet mask. Either ICS isn't set up correctly to provide values or the laptop isn't seeing ICS in a timely fashion. Since one NIC on the desktop (so on the ICS machine) is doing the same, it pretty much has to be an ICS problem.

- the blank Default Gateway will stop the laptop from finding the internet since that address has to point it to the ICS adapter so ICS can provide proper routing from your network to the internet. ICS failure again.

My suggestion for fixing this is to remove and reinstall ICS on the desktop.

Third item- Your D-Link AirPlus adapter appears to be active. Not seeing ICS but XP is assigning values to it so it is working. No default gateway as noted for the laptop so things won't work right but they do work.

- Your Intel(R) PRO/1000 adapter isn't live. If it is a built-in wired adapter, that isn't surprising and doesn't indicate a problem.

- Your WAN (PPP/SLIP) Interface adapter (virtual, software thing though) is getting what appears to be a valid IP address from your ISP's DHCP server as it should. All is well here.

- Your Tunnel adapter - if that indicates you have (or tried to have) VPN set up, you should know that VPN and ICS will not work together. Usual result is that neither works at all. If you aren't messing with VPN, then this is probably a result of loading the windows update that includes IP v6 support. In that case, use device manager and remove the thing. Probably not harmful but certainly clutter you don't need. And were it me, I'd go to the hotfix section in add/remove and get rid of IP v6 support altogether. I can't find a lot of detail but that may have been what broke ICS. May. Possibly.

Sorta Summary - As nearly as I can figure, ICS should be providing connection information to allow desktop and laptop to connect to the internet (via the PPP interface) and to each other. It is not.

Things to try - and listed in order of ease-of-doing

- simplest and may work
1) Uninstall ICS
2) Start Internet Explorer and select from the Menu
3) Set IE to "Always Dial My Default Connection "
3) Under Dialing Settings, select your ISP as your default connection.
4) Click OK and exit Internet Explorer
5) Install ICS

- if that fails, make sure you have all the information needed to reload your ISP connection and
1) Device manager and remove all the network devices you find.
2) You can't really uninstall TCP/IP on XP but you can come close by following These instructions. It will set things back to exactly as they were when the OS was first loaded.
3) Reboot and let your NIC reinstall then set things up from the beginning. Make ICS the last piece.
4) You should not have to mess with the laptop other than to refresh it's IP settings after you are done. Reboot is probably simplest.

 

At the moment, I checked and unchecked the ICS boxes several times and did the netsh thing and it all seems to work ok.

But in the future, if I do need to uninstall and reinstall ICS, how do I do that?

I thought it was merely a case of checking and unchecking the box on the Internet connection properties!

 

You can't really 'uninstall' ICS from XP but you can get it as gone as possible.

control panel~Add/Remove Programs
'Windows Setup' tab~Internet Options, and unselect the Internet Connection Sharing box.
