To convert the login screen wallpaper from Windows NT wallpaper to Jesus NT wallpaper, follow these steps:

Windows NT Workstation to Jesus NT Workstation:

1) rename "winnt256.bmp" in the WINNT directory to something you'll remember, if someone makes you switch things back.
2) download "winnt256.bmp" and place it in the WINNT directory in place of the old one.
3) log off, and the new wallpaper should pop up.

Windows NT Server to Jesus NT Apostle:

1) rename "lanma256.bmp" in the WINNT directory to something you'll remember, if someone makes you switch things back. Like that's gonna happen if you're running a SERVER. Unless you've hacked your way onto someone else's server, you naughty person.
2) download "lanma256.bmp" and place it in the WINNT directory in place of the old one.
3) log off, and the new wallpaper should pop up.

You may need to right-click on the links and save the bmp files manually, if you get a screen full of gibberish.

Not too hard. If this doesn't work, we will hold no responsibility for anything that might happen to you, your computer, your job, or your eternal soul. But we might call you a moron. Or, failing that, a nincompoop. You shouldn't be messing with things you know nothing about anyhow! My momma never raised any dummies, but I won't vouch for yours.
