Cisco routers support only MD5 authentication for NTP (http://www.oreilly.com/catalog/hardcisco/chapter/ch10.html).
I have found documentation to update ntp clients on unix systems using this MD5 authentication but not the equivalent for Windows 2000/2003 ntp client. Does someone knows if it is feasible and how?
