====13.2. Set date and time====

====Set date and time====

Accessing this section allows you to set the system date and time either manually or using a network time server. Pull-down menus for month and time zone ensure accurate entry. The server manager will reset the time automatically during daylight savings time. There are worldwide time zones with multiple selections for countries with multiple time zones. (including standard time zones, states/provinces and even cities). This ensures that regional variations in time zones and daylight savings time are accurately reflected.

{{DrawBoxTip|content=In order to make sure the network time server is set to your timezone, you should go through this screen once and manually set the time to be correct and with the correct timezone. After doing that, go back to this panel and set the server to use a network time server.}}

====13.3. Workgroup====

====Workgroup====

If you are using a computer on a local network and you wish to access the server via Windows file sharing, it is important that you are logged onto the same workgroup as your SME Server. This screen allows you to enter the name of the Windows workgroup the server should appear in. You should also enter the Windows server name. In order that you may later connect multiple locations using IPSEC VPNs, we suggest that you use a different name for each server. If you wish you can change the workgroup name to correspond with an existing workgroup.

The sample file contains a few examples of setting the system time for each machine and also for mapping a common drive for all Windows client.

====13.4. Directory====

====Directory====

Your SME Server provides an easy mechanism for creating a company directory. Each time you create or delete an e-mail account, your directory will be automatically updated with the new information.

At any time in the future, you can change the default information and have the new information apply to all new users or to all existing users as well. The field to do this is located near the bottom of the screen. Choosing "update with new defaults" is a convenient one-click method of revising your directory when, for example, your company has moved to a new address.

====13.5. Printers====

====Printers====

Your SME Server enables all users on your network to easily share a printer. The printer can be either locally attached to a parallel or USB port on your server or can be a network printer. All the server needs is some basic information: the printer name (which can be anything you want, as long as it starts with a lower-case letter and consists only of lower-case letters and numbers, with no spaces), a brief description (for example, "the printer down the hall") and the location of the printer - whether it's on the network or directly connected to your server through a parallel or USB port.

As a final item, you should be aware that in order to use the printers available through your server a user must be logged in to their client system with a user name and password that is valid on the server. For instance, if a user is logged in as tturtle on their Windows desktop and that user account does not exist on the server, the user will not be able to print to the printers managed by the server. Either the user will have to logout and log back in as a valid user or the tturtle account will need to be created on the server.

====13.6. Hostnames and addresses====

====Hostnames and addresses====

When you installed your SME Server, you were asked to provide a name for your system. That name and several other "standard" names are automatically configured in your system's host table during the installation process. This host table is consulted as part of the name resolution process. The "Hostnames and address" web panel allows you to modify this table and specify different host "names" for each domain on your system, as well as to control how those names resolve both for systems on your local network and also for systems on the larger Internet.

You would first change the location to "Remote" and then enter the IP address of your ISP's server in the field marked "Global IP".

=====Creating New Hostnames=====

Creating new hostnames simply involves selecting one of the links at the top of the Hostnames and addresses panel and filling out the appropriate fields.

=====13.6.2. Reserving IP Addresses Through DHCP=====

=====Reserving IP Addresses Through DHCP=====

Another task you can perform through this panel is to reserve an IP address for a given system based on its Ethernet address. For instance, you might have another intranet web server within your company that you want to always have the same IP address. One method of assigning that address is to manually configure the client machine to have a static IP address. The negative aspect of doing this is that if you later want to change the network settings for that machine, you must manually go and configure that machine. An example would be if one of your DNS servers changed its IP address. Additionally, you have to keep track somewhere of the fact that you have assigned a specific IP address to that machine.

Once you have determined the client's Ethernet address, click on the link to create a new hostname for a local host. Add the hostname of the target system, the Ethernet address along with the desired IP address into the web panel. From this point on specified IP address will only be provided to a client system with the matching Ethernet address.

====13.6. Domains====

====Domains====

When you are supporting multiple domains on a single server, each domain being served is referred to as a virtual domain . (The strict definition of virtual domain is when a single IP address is shared between multiple domains.) When you create a virtual domain using this section of the server manager, your SME Server will be able to receive e-mail for that domain and will be able to host a web site for that domain.

{{DrawBoxWarning|content=While the server is prepared to offer web and e-mail services for this virtual domain, there is one more step that must occur. In order for users on the Internet to successfully connect to your machine using the virtual domain, you will need to work with your ISP or whoever controls the DNS entries for your virtual domain to have the appropriate DNS entries pointed to the IP address of your server. For instance, your ISP will need to configure an MX record for the domain in order for you to receive inbound e-mail to that domain.}}

====13.8 E-mail====

====E-mail====

=====E-mail Retrieval=====

=====E-mail Retrieval=====

Finally, if you have "multidrop" mail service you need to select the sort method used by the server to decide which user each message should be delivered to. Your server has a default method for this (it examines various headers such as "To" and "Resent-To") which works in most circumstances but is not suitable for certain purposes such as mailing list messages. Some ISPs add a header to each e-mail message which can help your server determine the correct recipient. If your ISP does not add a header to multidrop e-mail, select the "Default" sort method and ignore the "select sort header" field. If your ISP does add a header to multidrop e-mail, then select "Specify below" and enter the header tag provided by your ISP. Because you will experience problems with mailing-lists when using multi-drop e-mail, we strongly recommend that you work with your ISP to have a special header added to each message. The "Default" sort method should be only used as a last resort.

====Review Configuration====

This section of the server manager summarizes how your server is configured. This is the data that you entered during the installation process and possibly changed later through the server console or the server manager. As you can see from the screen below, this is essentially a report that you can print out for your records. You do not have the ability to make changes from this screen.
