Removing Client Services for Netware (not typical)

When I try to create a profile for my son, and change the way users log on I get

"Client Services for Netware has disabled the Welcome Screen and Fast User Switching. To Restore these features you must unistall Client Services for Netware"

I followed the usual protocal...

Went into network connections
properties
deleted the closest thing I had Microsoft Netware or whatever-
all that is left there is
- File and Printer Sharing
- Qos Packet Scheduler
- Internet Protocal

My babysitter was messing around with her IPOD on here about the time I noticed this.

Also someone said to delete the Novell programs (but I can't find any)

I just want my son to be able to log on to his profile-

How do I get this crap off here?
