Creating a share on a remote computer

Setting up a VPN connection

You can establish secure, multiple-protocol VPN connections over the Internet using PPTP. By dialing into your ISP's point of presence, you can access corporate networks and programs without dialing directly into your company's network. To use PPTP to connect to a server across the Internet, you must install the PPTP...

Find another location for your DHCP backup

DHCP is responsible for significantly easing our workload in managing IP addresses. The DHCP service does back up its database and files.

A win WINS situation, part 1

Here's some information that can help you determine if WINS is appropriate for your network. Do implement WINS in small TCP/IP environments.
