Novell And Winxp (should B Simple Question)

hi all

I have this XP box..actually quite a few of them

anyway.. all of them are running novell for authentication purposes.

now what I want to do is change the picture of the login screen (the one that says press ctrl alt delete for login)

in win2k and earlier, all i had to do was change the bitmap under the winNT directory and that was it.

in XP, this is not the case. If i change the picture (after i did a search for it) it did not change it. the filename is nwelcome.bmp

if anyone has gone around this issue, any help will be most appreciated


thanks,
