IP address conflict
Hi
My SO's computer is running XP Home and regularly gets an error message indicating an IP address conflict when my test machine is up. All addresses have been manually assigned and there is no apparent conflict. Addresses are 192.168.1.x, x = 1(modem),2(SO),13(me), and 100(test). Is corruption a possibility? She was having intermittent crashes until I ran sfc -purgecache. TIA Jim |

You've only got 4 computers and a lot of numbers to choose from. Some things just aren't worth spending a lot of time troubleshooting, and this seems like one of them, unless you've got some particular attachment to that set of numbers. |

IP address conflict
I tried that, but nothing happens. No error reported, no address assigned.

IP address conflict
Windows remembers every Local Area Connection ever established
on your PC. It could be that a inactive NIC/LAC is the root cause of the conflict. Check Device Manager (Click Show Hidden Devices) Network and see if you have numbered, multiple instances of the same NIC. Also, check Network Connections and see what LAC is present. If it's numbered then you have multiple LAC's stored in the Registry. "nofixed" wrote in message ... I tried that, but nothing happens. No error reported, no address assigned.

What exactly is it that you have at 192.168.1.1? Modems don't have IP
addresses. Perhaps a DSL router or something like that? If so, is it DHCP server enabled? If so, configure it so that it passes out addresses above your highest static address. You have a system statically assigned .100, change the DHCP server to assign .129 and above. "nofixed" wrote in message ... I tried that, but nothing happens. No error reported, no address assigned.

Some modems do have a web interface. I know my DSL modem has, it also has DHCP. but I use a router so its not used. -- Admiral Michael ------------------------------------------------------------------------ Admiral Michael's Profile: http://forum.osnn.net/member.php?userid=72 View this thread: http://forum.osnn.net/showthread.php?t=43920 |

I tried that, but nothing happens. No error reported, no address assigned. Jim I am presuming you are using ICS/IPM (Internet Connection Sharing in Windows world/IP Masquerading in *nix world). I suspect this is because you are using a non-standard IP range on the host machine and the client can't find it with either DHCP (Automatic) or static IP settings. Although it is possible to use ICS with static IP addresses Windows doesn't like it and I've had best results using the defaults. In addition you are using an IP range that is non-standard for ICS/IPM. The host standard IP configuration is 192.168.0.1, not 192.168.1.1. I've also found in changing IP configurations that Windows keeps old values in the registry for default gateway and DNS on the client machines based not only on IP address but machinename/hostname, that can cause problems if the real gateway address or machinename has changed. I've had to search the registry for Default gateway entries and delete them. Also if you are using an ethernet switch or "smart hub" that builds an internal address table it may need to be power-cycled after configuration changes are made in order to re-build its table. So, if I were you I would approach it like this: Set the host machine up with default settings for ICS on the dialup connection which will make all the necessary IP settings for you on its NIC, set the client machines to obtain IP address automatically, search the registry for Default Gateway entries on all client machines and delete them if they are incorrect, shut everything down except the ICS host and modem, bring up the network device (hub, switch), then power up the Client machines. It may also take several restarts of the clients to get the addresses stablized.
