Well as Frank recommends a second nic will help to protect your network and
definitely help the system perform more like it was designed to...
You could always ask your boss what price he puts on having a secure system
and having the company's confidential information more secure

But if he wants one nic
Internal or single network adapter configuration
These settings are for all servers. The configuration applies to a single
network adapter and to the local network connection adapter in a
two-network-adapter configuration.
  1.. Verify the Domain Name System (DNS) pointers. To do this, follow these
steps:
    1.. Click Start, point to Control Panel, and then click Network
Connections.
    2.. Right-click Server Local Area Connection, and then click Properties.
    3.. Click Internet Protocol (TCP/IP), and then click Properties.
    4.. Do not select the Obtain an IP address automatically or the Obtain
DNS server address automatically options. The IP address for the server
local area connection must be a statically assigned address. Make any
changes to the static IP address or to the subnet mask on the local network
connection by using the Change Server IP Address Tool.

    In the Internet Protocol (TCP/IP) Properties dialog box, click the Use
the following IP address option. In the following boxes, type the IP address
or subnet mask, as appropriate:
      a.. IP address Type the static private IP address for the local area
connection adapter that resides in the Local Area Network (LAN). For
example, type 192.168.16.2.
      b.. Subnet mask Type the static subnet mask for the local area
connection adapter that resides in the LAN. For example, type 255.255.255.0.
      c.. Default gateway Leave this box blank, or type the IP address of
your router (if you are using a router).
    5.. Select Use the following DNS server address. In the Preferred DNS
server box, type the IP address of your server's local area connection.
Leave the Alternate DNS server box blank.

    Important Use the IP address from the server's local area connection for
the preferred DNS server on the external network connection. Do not use DNS
that is provided by your ISP or router, and do not click the Obtain DNS
server address automatically option.
    6.. Click Advanced, and then click the DNS tab.
    7.. In the table under DNS server addresses, in order of use, edit the
table so that it only has a single entry for the IP address of the server's
local area connection.
    8.. Use the default settings for the remaining DNS properties; click to
select the Append parent suffixes of the primary DNS suffix check box, and
then click to select the Register this connection's addresses in DNS check
box.
    9.. Click the WINS tab.
    10.. In the table under Windows Internet Name Service (WINS) addresses,
edit the table so that it only has a single entry for the IP address of the
server's local area connection.
    11.. Use the default settings for the remaining WINS properties: Click
to select the Enable LMHOSTS lookup check box, click Enable NetBIOS over
TCP/IP , click OK, and then click OK again to return to the Network
Connections window.
  2.. Verify the DNS server configuration. To do this, follow these steps:
    1.. Click Start, point to Administrative Tools, and then click DNS.
    2.. Click your server's name under DNS, and then right-click Properties.
    3.. On the Interfaces tab, verify that the server's local area
connection IP address is listed in the Listen On: IP Address table.
    4.. Click the Forwarders tab.
    5.. Under Selected domain's forwarder IP address list, type the DNS
server addresses that were provided by your ISP.
    6.. Click to clear the Do not use recursion for this domain check box.
    7.. Click Apply, and then click OK.
