Crossover Network Connection

[Patrick]

I had 3 machines as follows
Desktop1:
Win2K Professional SP4
fixed IP: 10.11.1.1
Subnet Mask: 255.255.255.0
Default Gateway: 10.11.1.2
Computer Name: Machine1
Workgroup: MyDomain.MyDomainDNSSuffix
NETBIOS over TCP/IP: Enabled
Client for Microsoft Network + File & Printer Sharing Enabled

Laptop1
WinXP Pro SP1
DHCP Enabled
Alternative Fixed IP: 10.11.1.2
Subnet Mask: 255.255.255.0
Alternative Default Gateway: 10.11.1.1
Machine Name: ws0001011
Domain: MyDomain
NETBIOS over TCP/IP: Enabled
Client for Microsoft Network + File & Printer Sharing Enabled

Laptop2
WinXP Pro SP1
DHCP: Disabled
fixed IP: 10.11.1.2
Subnet Mask: 255.255.255.0
Default Gateway: 10.11.1.1
Computer Name: Laptop2
Workgroup: MyDomain.MyDomainDNSSuffix
NETBIOS over TCP/IP: Enabled
Client for Microsoft Network + File & Printer Sharing Enabled

I could connect Laptop1 and Desktop1 together using a CrossOver UTP Cat 5
cable to share 5.

But I cannot connect Latop2 and Desktop1. They won't even PING each other,
despite trying
1) Emptying default gateway on both machines
2) Setting default gateway to the other machine's IP
3) Setting WINS to the other machine's PC

How could I fix this?? Note
1) I have disabled software firewall on both machines and still they won't
even Ping. No
2) The NIC on Laptop2 is working, as I managed to plug it into a network
using DHCP previously
3) On both machines I made the observations that the Byte Sent statistics
keeps going up slowly, but the bytes received remained at 1 or 2 byte!
4) Netstat /n does not show connection to the other machine
5) If I try to map to the other machine, I get failure, and netstat /n
indicate a TIME_WAIT connection on port 139 and 445 on the other machine

SOS SOS!

Get an Ethernet hub or Ethernet switch.

If you have Cable or DSL Internet, get a Cable/DSL Router such as the Linksys BEFSR41.

Do you network properly !

I don't need that because laptop1 is being replaced and I will never have
more than 2 computer that needs to be connected together.

 

[Yves Leclerc]

A router will help you with the network setup and will protect your entire
network with a NAT firewall.

 

[David H. Lipman]

Never say never - it lasts forever.

At less than $10.00 US per port your argument doesn't hold water.

The Cable/DSL Router I suggested has an embedded 10/100Mb/s Ethernet switch and has numerous
other advantages (DHCP server, simplistic FireWall, PPPoE connector, etc). Yet, it can be
obtained for $40.00 ~ $50.00. It wasn't too long ago I was paying more than $100.00 US per
switched port.

I could connect Laptop1 and Desktop1 together using a CrossOver
UTP Cat 5 cable to share 5.

But I cannot connect Latop2 and Desktop1. They won't even PING
each other, despite trying
1) Emptying default gateway on both machines
2) Setting default gateway to the other machine's IP
3) Setting WINS to the other machine's PC

1 & 2) When connecting two computers with crossover cable, a Gateway
setting is meaningless. (Unless, of course, one computer has 2 NICs and
is running ICS to the internet.)
3) WINS is not necessary if both machines are on same subnet. They
will find each other by broadcast.

My guess is that the two computers are mismatched on Speed/Duplex
settings. When cross-connecting two computers together, the "auto"
setting for speed/duplex doesn't always work. Try going to Network
Control panel or Device manager and find the Configuration for the NIC
and fix the Speed/Duplex to be the same for both machines.

HTH & Good Luck,
John

One other observation I made is that when I did a
ipconfig /all

Node Type shows up as "Hybrid" on one machine and "Broadcast" on another,
but I couldn't figure out how to change it?

Also, with a cross over connection, is it possible to have a dial up
connection from on machine, and the other maching "sharing" the dial up
connections? If so, how? I think Internet Connection Sharing only allows
sharing with a Parallel cable?

The node type determines what method(s) NetBT will use to register and
resolve names. A B-Node [broadcast] uses Broadcasts, a H-Node [Hybrid]
uses the name server first, then broadcasts. The system defaults to a
B-node if there are no WINS servers configured and defaults to H-node
if there is at least one WINS server configured. This can be overriden
by making registry changes.

Also, with a cross over connection, is it possible to have a dial
up connection from on machine, and the other maching "sharing" the
dial up connections? If so, how? I think Internet Connection
Sharing only allows sharing with a Parallel cable?

I'm sure this is possible with the right software. I can't help you
here.
