Help Me With Ics Please! Internet connection sharing problem.

So, I have 4 computers at office, and they all share same DSL internet connection. We share the connection on 1 computer, while others acces it via Internet connection sharing. And everything works just fine, until I shutdown all computers and start them up again. Then they loose internet connection, in IE or Firefox there is no connection, but the weird thing is that in right bottom corner of taskbar it shows that blue "computer icon" that there is LAN and another one that there is internet connection via shared computer bla bla... IE and Firefox acts like there is none internet connection available... Please help me out with this one, Im really out of ideas now...Oh, and all computers are using Windows XP professional with SP2 (ly one is on SP1).

Check out these two links to see if they are of any help:

Practically Networked Link

I think the second link gives more in depth on ICS and setting it up. The windows networking site goes straight to setting it up. Go with the second one if the first one is confusing.

Well I don't remember this quite well, but I you may try these two. And both without using the ICS1) Configure the default gateway as the IP's machine that has direct access to the internet.or2) Configure the default gateway the same as the default gateway of the machine connected to the internetI have done this way many times (but I can't rememeber exactly which gateway of those two worked, but try both).So whenever the machine connected to the internet is turn on, any other computer connected to it, and configure as said should have access to the internet.

thanks for your reply... I'll try these suggestion, I hope they work, I must go on vacation soon, so people at my office must be able to work without my assistance
