My environment is Windows 2003 server and many XP machines.
I have created IP security policy on Domain Controller and it works fine.
Now I want to enable all rules on working hours, e.g. 9am - 6pm. And disable
some rules outside of those boundaries. Is it possible to configure is in
such way? How?
Now I simply have made script, which automatically stops IPSec service on
6pm and starts on 9am. But I believe, there should be more intelligent way
to do it.

Thank you in advance!
