"Log on to Windows" screen changed

For some reason, my "log on to Windows" (welcome ?) screen has changed. I tried going through Control Panel.User Accounts.Change the way users log on or off, but I get a error box "client services for Netware has disabled the Welcome screen and Fast User Switching. to restore these features, you must uninstall Client Services for Netware.

I just recently started using my wireless internet on this laptop. Will that mess this up?

 

No. That's what so puzzling. I can seem to find this file either.

 

Thought I'd leave an update.

Went to Microsoft support and found this article: #315347 having to do with Client Services for Netware. For once, following their instructions, something worked!

Only thing I can figure out is that when I logged in at a local Internet Cafe, Client Services was downloaded. I found it under my built-in modem for the laptop. Once you get rid of it, you can go back to "change the way users log on or off" and it will let you change things.
