SUMMARY
Microsoft recommends that you DO NOT install for &quot;No Network&quot; if a Windows-supported network is actually installed.

MORE INFORMATION
The VNETBIOS and DOSNET devices automatically detect if they are necessary, and do not load if a network is not installed. They are always specified as a default in case Windows is installed for No Network, but a network is actually present.

A case in which this could occur is when Windows 3.0 is installed while the network is not loaded. Windows Setup does not detect a network, so it installs for No Network. When the network is later activated, VNETBIOS and DOSNET detect the network presence and prevent compatibility problems. However, no network functionality is present without a Windows network driver installed. Additionally, the system cannot print through a network- redirected printer port if Windows is not specifically installed for a network.
