Re: Windows Firewall fails to start on Windows Server 2003

But what if your not using RRAS? The RRAS service will be disabled and not
running on SVR 2003 STD. Sometimes a reboot will generally fix the issue but
sometimes it will not. BTW I'm part of a management team that supports quite
a few servers and we see this issue offten.
