Script to open Remote Login in "sharing" not working after move to 10.5

Question

Under 10.4 I sued the following script to open Remote Login (tick the box). Under 10.5.6 it does not work.
do shell script "/usr/bin/open /System/Library/PreferencePanes/SharingPref.prefPane"
activate application "System Preferences"
tell application "System Events"
tell process "System Preferences"
click checkbox 1 of row 6 of table 1 of scroll area 1 of tab group 1 of window "Sharing"
delay 3
tell application "System Events"
quit application "System Preferences"
end tell
end tell
end tell
I get the following error:
System Events got an error: Can’t get tab group 1 of window "Sharing" of process "System Preferences". Invalid index.
Anybody know why?
