The SET Command Is Currently Disabled Recovery Console

ok, lets say you are trying to change some configurations while you are in the windows xp discovery console and when you execute a command like this:

SET AllowWildCards = TRUE
SET AllowAllPaths = TRUE
SET AllowRemovableMedia = TRUE

you get an error like this:

The SET command is currently disabled. The SET command is an optional Recovery Console command that can only be enabled by using the the Security Configuartion and Analysis snap-in.

ok, so how do you about enabling the Security Configuartion and Analysis snap-in if you can't boot up to the system?

i found a fix around, for example, if the bad computer had windows xp installed on it, you can bypass this message by using a windows 2000 recovery console disk instead of a windows xp installation cd
