Internet Connection Sharing Generates Error Message When IP Address 192.168.0.1 Is Already in Use

• Microsoft Windows 2000 Advanced Server
• Microsoft Windows 2000 Datacenter Server
• Microsoft Windows 2000 Professional
• Microsoft Windows 2000 Server

SYMPTOMS

When you try to enable Internet Connection Sharing (ICS) on your Windows 2000-based computer on a network, you may receive the following error message:

Cannot enable shared access.

Error 783: Internet Connection Sharing cannot be enabled. The LAN connection selected as the private network is either not present, or is disconnected from the network. Please ensure that the LAN adapter is connected before enabling Internet Connection Sharing.

CAUSE

This problem can occur if the Internet Protocol (IP) address 192.168.0.1 is already in use on another computer on your network. When you enable ICS, your computer is assigned the 192.168.0.1 IP address, and if this address is already in use on another computer, the error message listed earlier in this article is generated.

RESOLUTION

To work around this problem, disconnect the computer using the 192.168.0.1 IP address from the network, or change its IP address to something other than 192.168.0.1.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.
