Windows

First of all, I believe IE3 should be installed by default on NT4. See if you can use it to browse out to the web (try www.google.com). If you can browse the web and if you didn't specify a proxy in the 'Internet options' section of IE, then you won't need to plug in a proxy address or port number for IE 5's setup app.

I've seen the same message: "Setup was unable to download information about available installation sites." on other NT4 systems I've used. There are a number of reasons whyyou might receive this message: corrupted dll files, invalid registry settings, etc. The Microsoft kb article 189679 ( http://support.microsoft.com/?kbid=189679 ) points out several resolutions.

In my specific cases I had to use resolution step number 5: "If they exist, rename the following files in the Windows\System (or Winnt\System32 for Windows NT) folder to an .old file extension:
Advpack.dll
Inseng.dll
Jobexec.dll
Urlmon.dll
Wininet.dll
Wintrust.dll
Url.dll"

Good luck!

this was copied from http://www.petri.co.il/download_the_full_ie_package.htm it works great -
"Yes! First, download the IE6 SP1 setup program from ERLINK "http://www.microsoft.com/windows/ie/downloads/critical/ie6sp1/default.asp" \t "_blank" HERE (500kb basic setup program. The full IE package might go as high as ~44mb depending upon your selection).Go to the folder where you've placed the above file. Open a Command Prompt (CMD) in that folder, then run the following command in the CMD window:ie6setup.exe /c:"ie6wzd.exe /d /s:""#E"""Note: Just copy and paste the above line. Don't try to be a wise guy. Copy the damn line! I've received quite a few feedbacks about the accuracy of this tip, and always they got the syntax wrong. Copy and bloody paste! Oh, and yes, this tip works for IE 6 SP1 too.It will let you customize the d/l parameters.BTW, this tip also works for IE 5 and IE 5.5. Just replace the "6" in the previous line with a "5".You can also choose to download all IE versions inone go. For example, if you choose to download the version for Win9X, the version for NT, the version for W2K, and the version for Win ME - all the files will go to one location - a folder named "Windows Update Setup Files" - and you can then burn this folder to a CD and use it to install IE on any OS version you want."
