Whoa, I don't think your problem is that you have to reset SIC on your Management Server. If the only issue your having is that you can't log into your Management Server through the GUI clients, it doesn't sound like you need to reset SIC. You would have to reset SIC if you couldn't communicate between modules (e.g. Your Management Server can't push policy to your Firewall)

There are a few things I would try.

1) Do a cpstart on your management server to make sure the Check Point Products are started.

2) Run a cpconfig from the Management Server. Go into the "GUI Client" option. Make sure your IP address or network is defined as a GUI Client, or that you have "Any" which would allow any IP to connect.

3) If there is a firewall between you and the Management Server, make sure that you are allow CPMI to pass through the firewall from your machine to the Management Server.

Confirm that all of these settings are correct and let me know what happens...
