When "Rainmail Server" is installed, it gives a default name of "server" to the machine it is installed on. You may want to change this name to something more meaningful or in accordance with your corporate policy.
Network Information
As your company grows, your LAN will grow. Rainmail Server helps you take control of your network in a centralized location. Adding and moving machines in the LAN is as simple as clicking on a few items and adding some information.Each machine in your LAN is identified by an unique address (called an IP address of the form "192.168.1.1") and a name. When you add or remove a machine from your LAN, you will need to enter that information using the nodes in this section. In addition to keeping a list of all the machines on your network, Rainmail Server acts as a "Name Server" which maps from names of machine in your LAN to IP addresses and vice-versa. Your Rainmail Server also caches mappings between machines and IP addresses of the machines you have visited recently on the Internet. This speeds up your Internet access.

This panel helps you to change the machine name. The current name of the machine is displayed in the "Machine Name" edit box. To change machine name, enter the new machine name (without the domain name) in the "Machine Name" edit box and press "Change". The successful completion of this operation is indicated by a dialog. The current Internet connection will not be affected in anyway by this change.
6.3 Specify IP address and Network Class
"Rainmail Server" needs to be assigned an IP address to interact with rest of your internal network. When installed, Rainmail Server picks up the IP address of the machine and you normally do not need to change it. However, there might be circumstances (like reorganization) wherein you would want to change the IP address and network class of your "Rainmail Server". In these cases, it does not suffice to use the OS function to change the IP address. You need to make use of this screen to change the IP address so that all information is updated appropriately.

To change the IP Address/Network class of your "Rainmail Server", Enter the new IP Address in the "IP Address" field, Select the new network class in the "Network Class" field, and Press "Set". Successful completion of this operation will be notified by a dialog. This setting will take effect when the system is rebooted. Therefore, please make sure you restart the system before further using the system.
This panel helps you in adding a machine to your LAN so that it can enjoy all the facilities offered by Rainmail Server. Any machine on your LAN needs an unique IP address through which it can be identified. Rainmail Server automatically generates an IP address for your new machine. This ensures optimal use of your available IP addresses. Adding a machine to your LAN has two parts. The first part consists of adding information about the new machine to Rainmail Server. The second part consists of setting properties of the new machine so that it can access the Rainmail Server. We will look at both the parts in this help.
Rainmail Server Changes:
Choose a name for the machine you want to add.
Enter the name of the machine in the "Machine Name" field
If the machine already has an IP address, enter the IP address in the "IP Address" field.
If this is a new machine and you want "Rainmail Server" to automatically assign an IP address, leave the "IP Address" field blank.
Press the "Add" button.

Rainmail Server will register the new machine in its database and will assign the given IP address (or a newly generated one if the "IP Address" field is blank) to the new machine.IP address of the machine can be found out by clicking on the "IP Information" node. Successful addition of this new machine is intimated by a dialog.
Setting Network Properties in your new Windows machine:
Click on "Specify IP Address and Network Class" under "Network Information" section in "Rainmail Server". Note down the IP Address displayed in the "IP Address" field.
From "Control Panel", Choose "Network" and double click on the "TCP/IP" section. In the dialog that follows enter the necessary information using the following values:
IP Information: Get the IP address from the Rainmail Server Configuration program.
DNS Address: <IP Address as found above>
Gateway address: <IP Address as found above>
Leave the other fields blank.
Testing adding a machine to LAN:
After both the above steps have been completed, open up a DOS prompt in the newly added machine and type in "ping <IP Address as found above>". If you get a "Request Timed Out" message, there are some problems with the configuration. If not, the machine has been successfully added to your LAN.
This panel helps you to delete a machine from your LAN. This may be necessary when you are removing old machines or as a part of reorganization.It is very simple to delete a machine from your LAN. Choose the name of the machine you want to add from the "Machine Name" combo box field. Then press the "Delete" button. The successful completion of this operation is intimated by a dialog.

WARNING!!!! This will delete all data currently present in the Share. Please make sure that the data is not required before completing this operation. Share should not be deleted when users are accessing it.
As soon as a machine is deleted from your LAN, it cannot see and be seen by the other machines. The deleted machine also stops having access to the Rainmail Server.
Every machine in your LAN needs to have an unique IP address. When a machine is added to your LAN (using the "Add Machine" panel), it is given IP address or assigned one by the Rainmail Server.

It is essential that you configure your machine with this IP address. This panel helps you find out what the IP address of a machine is. To find out the IP address of a machine, select name of the machine using the "Machine Name" combo box and press the "View" button. The IP address of the selected machine is notified by a dialog.
