SUMMARY
If you issue a net use * \\workstation\share /user:securityprovider\username password command on a Windows 2000-based computer that is running Internet Connection Sharing (ICS) or Network Address Translation (NAT), the computer may dial the Internet.



MORE INFORMATION
When you use the /user:securityprovider\username switch with the net use command, Net.exe assumes that &quot;securityprovider&quot; is a domain. Therefore, the client computer queries Domain Name System (DNS) for a domain controller in the &quot;securityprovider&quot; domain to begin Kerberos authentication. If an ICS or NAT host is acting as a DNS proxy, the DNS query is forwarded to the Internet. In a workgroup situation, it is sufficient to use the /user:username switch instead.
