I installed SP2 on several of our church stsrems ( in preparation to allow
them to access the internet ). Once SP2 was installed, the firewall could be
"turned on" on all but one system. When I try to enable the firewall I get
a message "We're sorry. The Security Center could not turn on Windows
Firewall." It suggests that I turn on the firewall myself by goint to
"Control Panel" > "Windows Firewall". But when I tried the options for
turning on the firewall are not active ( greyed out ).

Any thoughts on what I can do?
