have a three PC LAN connected using 3COM 3C410 phoneline
network cards and running on Windows Me. These PCs share
an Internet connection using Enternet 300 software,
an ADSL modem and a 3COM 3C905B TX Ethernet card. IE
works fine in the host computer, however in the client
computer it works only in FTP protocol. When I try HTTP,
IE is not able to receive any data except from the ISP's
own Web page. How do I fix this problem?
Older versions of Enternet 300 are not compatible with
Windows Me because of changes in the operating system.
Make sure that you have installed the latest version
of Enternet 300 on your system. You can also face this
problem if your Internet Explorer is not configured
to use Enternet.
Check the following link to find information on configuring
Internet Explorer to use Enternet:
I am running a Windows 2000 Advanced Server with
Windows 98/Windows Me on the clients and a DHCP server
for IP polling. While logging, some of the clients show
an error message saying "No domain server found
to validate your password". If I press cancel it
In Windows 98 and Windows Me, if you log on by canceling
the password, you will not be validated by the domain
server and hence will not be able to access the network
Make sure that you log in properly by providing the
correct login, password and the Domain server. Also
make sure that all the clients are connected to a single
How can I have share network resources like files
and printers in a LAN having both Windows and Linux
Samba is a protocol by which PCs on a heterogeneous
network can share various network resources. Windows
NT, OS/2, and Linux support Samba and various add-on
packages that achieve the same thing are available for
DOS, Windows, VMS and all flavors of Unix. You need
to install and configure Samba protocol for providing
interface between Windows and Linux machines.

I have a UTP network with 4 meter crossover UTP cable.
After installing a new 12 meter crossover UTP cable,
the network speed has slowed down by 80 percent.
The slowdown may be due to poor network performance
within a segment of your network or across the entire
network. This may occur occasionally, during times of
high usage. The causes can be found out using a network
monitor that will help in determining the level of bandwidth
being used across the network at the time of peak usage,
and the types of packets being transmitted.
We suggest that you can do the following to solve this
1. Check the cabling. Some cable connection might be
2. Configure the Network Interface Cards (NIC) properly.
3. Check for high numbers of packets from one IP address.
A malfunctioning network adapter card could be "chattering"
and sending lots of unnecessary packets.
4. Check to see whether any new applications have been
installed on the network. Perhaps a client/server application
is generating lot of packet traffic.
5. Network speed also depends on the number of users
currently working. The network congestion increases
as the number of users increase in a network.

What is the command in Windows NT for releasing and
listing IP Address of NIC?
ipconfig is a utility used from the command prompt to
display the network settings assigned and given by a
network. This command can be utilized to verify a
network connection as well as to verify your network
To release an IP Address use the following command:
This command releases the current DHCP configuration.
This option disables TCP/IP on the local system and
is available only on DHCP clients. To specify an adapter
name, type the adapter name that appears when you use
ipconfig without parameters.
To display information about the IP address, use the
This command produces a full display. Without the switch
/all, ipconfig displays only the IP address,
subnet mask, and default gateway values for each network
are the transfer rates for ARCNET, Ethernet, Token Ring
ARCNET: The maximum transmission speed is 10 Mbps. ARCNET
(COM20019/20/22) allows you to select the rate from
156 Kbps to 10 Mbps.
Ethernet: 10BaseT is the most common Ethernet system
and it provides transmission speeds up to 10 Mbps. Fast
Ethernet or 100BaseT provides transmission speeds up
to 100 Mbps.
FDDI: An FDDI network contains two token rings, one
for possible backup in case the primary ring fails.
The primary ring offers up to 100 Mbps capacity. If
the secondary ring is not needed for backup, primary
can run at 200 Mbps.
Token Ring: The IEEE 802.5 token ring technology provides
for data transfer rates of either 4 or 16 Mbps.
How does one change the DNS (Domain Name Server)
information for a site?
To modify the DNS information you will have to come
under any of the categories given below:
1. You should have registered directly from a Domain
Name registrar (Ex: Network Solutions or Register.com)
and have a Domain Management account with them.
a. If you have one, then visit your registrar's website
and log into your management account.
b. Click on Modify DNS settings link and remove the
existing DNS information first. Now enter the new DNS
2. If you have registered through a Web hosting provider,
then please contact the hosting administrator to change
the current DNS.
