Removing IPX from Client and proper settings

Finally got rid of last IPX server yesterday (yay!). Now its time to remove it from all the clients out there. I plan on using ACU in the login script to do this. Whats the dif between the "!RemoveIPXIfPresent=YES" in unattend.txt vs using the acu.ini Uninstall section?

Also, for an IP environment. What settings via the client do you guys recommend? Specifically the Protocol Preference tab. NDS and SLP? and always forget what the file caching and file commit should be set to. Using linux and netware servers still, if that matters. Any other tabs to worry about? Thanks

SLP is handled via DHCP.
