If the client has obtained an address from a DHCP server, click More Info to
identify the DHCP server, when the lease began, and when it expires. Four
additional buttons provide the following functions:
Renew—Sends a DHCPREQUEST to the DHCP server, updates the
lease, and updates any assigned values such as a default gateway or DNS
server.
Release—Sends a DHCPRELEASE to the DHCP server indicating that
the client is giving up its IP address and that the server is free to assign
that address to another client.
Renew All—Sends a DHCPREQUEST to all network interfaces to which
the Windows 95 client is configured.
Release All—Sends a DHCPRELEASE to all network interfaces to
which the Windows 95 client is configured.
If you want another IP address to be assigned to the client, select RELEASE,
then select RENEW.
PING is the most basic utility available to test, verify, and troubleshoot TCP/
IP connectivity within a network. PING sends an ICMP packet to a specific
host with a small amount of data and expects that host to respond with the
same data packet. If you receive a response, both TCP/IP and connectivity
between the two hosts are operational. If you do not receive a response, one of
the following conditions exists:
The host is not up.
A router between the connections is not up.
The client's TCP/IP stack is not functioning.
To run PING, from a DOS prompt enter the command followed by a hostname
or IP address, such as the following:
C:\> ping www.novell.com >
If TCP/IP is operational and connectivity exists between the hosts, you will
receive the following type of response:
