We have a network of about 20 users. DHCP services is provided by an internet router. The SBS does not have a static IP address. Should the server have a static IP address? I do not have access to the router because the ISP has a password on it. If I am able to change the IP to a static, are there other issues I would have to deal with a the same time?

Thanks,

George

Your server does not need a static IP address. However, if you are not running WINs, and you are having browsing problems, you will not be able to use LMHOSTS files.

Another problem could arise should you decide to host a web site on your server. In that case, you would need the resources of an outside company that specializes in Dynamic DNS.

In general, it's good for servers to have an IP address, especially if you want to fully use all the capabilities of SBS. Also, it's just good to know the IP's of your servers.

As for issues, if you need to remotely access your server from outside your LAN, you'll need to "open" your server via the router, or purchase a block of valid IP's from your ISP and use that in the DHCP instead of its default values. If you don't have to remotely access your server, just use the IP's provided by the router and just use one as static for your server. There will be a slew of options in the DHCP conifiguration of your router once you can get access to it.

Since SBS is installed full automatic you have an static IP-Adress in the A-Class Range for your NIC. If U ask how to connect the E-Mail and Proxy function from SBS to the Internet for your User?s so can answer the following:

E-Mail: Speak with your ISP about an MX-Record for your E-Mail domain. Normally if you?ve got an POP3 account you can use the pop3 connector for sbs from Microsoft to get your Mails from an existing Pop3 account to your Exchange Server, otherwise ask your ISP to Push incoming Mails for your E-Mail domain in cyles to your Exchange Server. All this requires an offical IP-Adress (static) for your E-Mail domain.

Proxy: For using the Proxyfunction U don?t need an static Ip-Adress on the internet ? side of your router. Customize the User-setting for proxy with the SBS Admin-console.
