That root.exe sploit is actually the Solaris sadmind/ IIS Unicode worm.
I've been on several incident responses at client sites and have seen it.
It zombifies a Solaris box using the sadmind exploit (shame on them) and
then scans a range of addresses for IIS b0x3n that are vulnerable to the
Unicode exploit (again, shame!). It copies cmd.exe to the scripts directory
and runs a search and change for index.htm index.asp default.htm and
index.asp and changes them to an anti -USA government (and anti spiderbox)
message.
