Hi. I came from XP directly to W7, non-Vista stop. I say this just in case someone tell me "same like Vista"I configured my networks in W98, W98SE and XP (never had ME) mainly by writing the adresses of mi PCs: 127.0.0.1 - 127.0.0.2 and so on (of course masking with 255.255.255.0) and using the 127.0.0.1 as the default gatway.This is because I have one PC as the "server" and the others as clients. I know, I must buy a router, but, you know... the crisis...Anyway, I need to know how can I manually configure this in W7. I cant find it...Thanks in advance.

The problem is with your choice of network addresses. This range should never appear in any network anywhere. Here's a quote from RFC 3330 127.0.0.0/8-ThisblockisassignedforuseastheInternethost loopbackaddress.Adatagramsentbyahigherlevelprotocoltoan addressanywherewithinthisblockshouldloopbackinsidethehost. Thisisordinarilyimplementedusingonly127.0.0.1/32forloopback, butnoaddresseswithinthisblockshouldeverappearonanynetwork anywhereVista and now Windows 7 adhere better to the RFC's. Even though those addresses may have worked in XP they technically shouldn't have. Change to using an IPrange designed for internal private networks like 192.168.x.x/24http://en.wikipedia.org/wiki/Private_networkKerry Brown MS-MVP - Windows Desktop Experience

If you are using internal address, you can use anything but 127.0.0.xxx. Those are strickly used for loopback purposes. For internal addresses, use 10.0.0.xxx, 172.16.0.xxx, or 192.168.0.xxx.

I'm sorry, I know this. The addresses I used were 192.168.0.1...... (an smilie should be usefull here :D)Anyway, despite the address, what I want to know is how can I wote this. I can't find the place to configure the IP addresses.Thanks.

HiYou do not need to configure manually IP address of your slavecomputer, because computer you use as server can auto asign IP addresses using DHCP.As 127.0.0.1 as well 192.168.0.1 are not used forgeneral privateIP addresses.IP address 192.168.0.1 must be IP address of second NIC(internal network) of your server computer (first NIC must be connected to internet, and second NIC to your slave computer)If you still think you can configure your network by yourself, go here Control Panel\Network and Internet\Network and Sharing Centerthen click change adapter settings from left pane and set TCP/IPv4 settings you want

Thaks. This is what I couldn't found, I mean: where in the W7 is the manual configuration :DAnyway, It's OK. I am a "formatter", I make experiments with my PC and many times I end formatting it. OK, I'm a kind of stupid, I accept it :D But it's my nature. I'm like the scorpion ;)What I want to say is: sometimes the "slave" takes the addresses via DHCP, sometimes don't...I don't understand what you say about the 192.168.0.1 address (my poor english). I do this: "server": 192.168.0.1 - "slave": 192.168.0.2 - default gateway (slave): 192.168.0.1Is this wrong?Thanks.

Hello DrGerry!Last settings you listed are correct and may be used for manual configuration of simple network with few computers, as probably is in your case.I advice you to make disk image before to start experimenting, so you will be able to restore quickly initial system state after you finish, by restoring system partition from image.If you want you can check event viewer on servercomputer for problems preventing smooth DHCP functionality.

Darrien,Actually you can't use any 127.x.x.x addresses. It's a /8 not a /24 network the loopback RFC. A difference between 16776960 addresses :)
