Instead of setting the time manually, you can use a network time server. A time server is a device on the Internet that keeps accurate time and is able to communicate the time to other computers over the Internet using the Network Time Protocol (NTP) . Many organizations around the world provide Internet time servers for free.

{{DrawBoxWarning|content=After you start using a network time server, you should NOT set the time or date manually. If you do so, the network time synchronization will no longer function.}}

This screen in the server manager allows you to configure your server to connect regularly to a time server and synchronize the clock on the server with the time provided by the time server. To do this, simply check the box for "Enable NTP Service", add the domain name or IP address of the time server in the space provided and click "Save NTP Settings". Using a time server is optional but doing so can greatly increase the accuracy of your system.

For more information about using a network time server, visit http://www.ntp.org/. You can also find a list of publicly available time servers at http://www.eecis.udel.edu/~mills/ntp/servers.htm. You should always use a secondary time server (also called a stratum 2 server) to lighten the load on the primary time servers.

Also in this section, you can specify whether the server should be the domain master for your Windows workgroup. Most sites should choose "Yes" unless you are adding an server to an existing network which already has a domain master.

{{DrawBoxWarning|content=If you have a Windows NT server or Windows 2000 server on your network that is functioning as a network server, you should most likely answer "no" because that other server will act as the domain master.}}

If you do configure your system to be the domain master, a special Windows share called NETLOGON is created with a DOS batch file called netlogon.bat. This batch file is executed by Windows clients that have been configured to "Logon to domain". The netlogon.bat file we provide by default does very little, but advanced users can, if they wish, modify this script to set environment variables for their clients or provide automatic drive mappings.

If you choose "Network printer", you will see an additional screen that will ask for the hostname or IP address and the network printer name. Enter that information where requested. For the network printer name, you can use the default setting, raw, unless you have some reason to do otherwise. (raw is the name used by most network printers for their main print queues.)

{{DrawBoxNote|content=For maximum flexibility in making changes later, we suggest that you enter the hostname for a network printer here and enter the IP address of the printer through the Hostnames and addresses panel of the server manager. This allows you to have one central location listing IP addresses and allowing you to make changes. Note that many modern network printers can be configured automatically. To do so, enter their hostname, IP address and Ethernet address in the Hostnames and addresses panel.}}

Note also that the server printing system does not perform any filtering and passes the print requests directly from the client computers to the printer in the "raw" or "pass-through" machines. For this reason, the SME Server does not have a list of "supported printers". Most printers are supported as long as the appropriate driver is installed in the operating system on your client computers.

Where this gets complicated is when you want "research.mycompany.xxx" to be accessible both inside and outside your local network. The challenge is that your local IP addresses are only accessible inside your network. For that reason, the target computer system will need to have two network interface cards - one connected to the internal network and one connected to the external network. You would then enter both IP addresses in this screen in the "Local IP" and "Global IP" fields.

Be aware that you can point the virtual domain to either the primary web site or to one of the i-bays . You cannot point a virtual domain to a subdirectory that you simply create inside of the primary web site file area. You need to use an i-bay instead.

{{DrawBoxNote|content=When you are entering the name for the virtual domain, you should supply the fully-qualified domain name . This is the full name of the domain, including any extensions like ".com", but without any prefixes like "www" or "ftp". For instance, you can create a virtual domain by entering "tofu-bird.com", but not by entering "tofu-bird" or "www.tofu-bird.com".}}

Note that in all cases the server will act as a DNS cache/proxy/forwarder and so all domains will actually _technically_ be "resolve locally", but the dns cache will forward them to the chosen DNS servers.

{{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.}}

* Forwarding address for administrative notices: The default address for administrative notices (i.e. undeliverable mail, backup notifications and other status/error messages) is "admin". If you'd like those messages to be sent elsewhere, enter the address here.

* E-mail to unknown users: This field allows you to choose whether incoming messages to unknown users are bounced back to the sender or forwarded to the system administrator. Some users prefer the latter setting because it allows them to catch and reroute e-mail that was incorrectly addressed.

* Internet provider's SMTP server: Normally the server will send outgoing messages directly to their intended destination. If, however, you have an unreliable connection or are using a residential Internet service, it may be advisable to route e-mail via your provider's SMTP server. In that case, you should enter the SMTP server's hostname or IP address here.

* POP and IMAP server access: The options are "Private" and "Public". The former allows access only from your local network. The latter allows access from anywhere on the Internet. Think about this carefully. On the positive side, choosing "Public" access allows any of your users to retrieve their e-mail via POP/IMAP from anywhere on the Internet. The negative side is that when you do this, you are reducing your level of security, as you will now have two more services (POP and IMAP) that are listening for connections across the Internet. Both protocols also involve transmitting your password across the Internet in plain, unencrypted text, opening up the possibility that someone could intercept the packets and learn your username and password. Allowing such access can be a great convenience to your users, but if security is a concern you should consider using encrypted webmail instead.
