Secure storage for passwords for admin scripts?

[Max]

I have a collection of system admin scripts (on Win 2k) that I would
like to automate the execution of. However, some of them require the
use of logins with admin rights, and would therefore prefer not to
store the IDs in the clear text of the source. If memory serves
correctly, the "compiled" .pyc files do not provide much security in
this area.

Are there are recommended methods for supplying scripts with login
information in a secure fashion?
