Problem configuring CISCO 1841 router

I am having a problem removing IPX from our CISCO 1841 router.   I log into the router and goto config t and make my updates.  After I do a control Z and show config, IPX is stil there.  It doesnt look like I did anything.  

I would greatly appreciate any help.   Below is the configuration currently on the router.
