The IP addresses that are being used in your network are being assigned to an Internet Zone, which denies the request from other computers to be able to communicate with you. There is a simple way to fix this issue. Please follow these steps to set the zone of the adapter to Trusted in order to allow this type of communication. 

1. Open the SecureIT Management Console
2. Select the Advanced Settings button
3. Select Firewall
4. Select Network Adapters
5. In the right-hand display, highlight the network adapter's IP Address
6. Once highlighted, change the zone from Internet to Trusted from the pull-down list below the adapters
7. You will see the IP Address Zone type change
8. You will have to repeat this for all computers in your network that have SecureIT
