This article was previously published under Q156323



SYMPTOMS
In Windows 95, disabling "Log on to network" in Dial-Up Networking Advanced Options may disable Microsoft Networking. This will occur if Windows 95 does not have a network card or is using a hardware profile with no network card. Sockets-based applications such as FTP, Telnet, and Ping will still function.



CAUSE
The "Log on to Network" option may be confused with logging on to the domain, when actually the "Log on to Network" option enables or disables NetBIOS, if no network card is configured.



MORE INFORMATION
To verify this setting, open Dial Up Networking, secondary click your connectoid, choose Properties, select Server Type.

If the "Log on to network" option is disabled you may see the following errors.

Network Neighborhood will report:

Unable to Browse the Network. The network is not accessible

Mapping a drive in Explorer will report:

Not logged on

A net use from the command prompt will report:

Error 3787: You must log on before performing this operation.
