Odd Syssetup.dl_ Error

[syntax01010]

For some reason, when attempting to expand the syssetup.dl_ from my updated XP SP2 source(and i've checked, its not set as read-only or hidden), I keep getting the error message "warning cannot expand a fille onto itself" ? I've never seen that error message before. Normally I just browse with command prompt to the folder i make a copy of syssetup.dl_ in and type expand -r syssetup.dl_ and it expands and gives me syssetup.dll to edit, but for some reason it won't expand to a .dll i can edit now?

Also, I went to look for Astalavista post that was formerly a sticky on this forum(it had syssetup and WINNTBBU.DLL as a rar file to download. Now its not sticky? The files aren't there to download anymore either.
