MSWC.Tools and windows 2003

[dave]

Hello
Can any one tell me what value range for this code?

set objTools=server.CreateObject("MSWC.Tools")
Response.write objtools.Random()


I executed code several times but couldnt figure out the
value range and logic.

Reason for asking is we are moving to windows 2003 server
and now v need to change above code from our site..

Any suggestion would be appreciated..
Thanx
dave
