IP Conflict Preventing Network Access
I have a home network through a linksys router. 2 Vista m/c, 1 XP. Recently
returned from vacation where all m/c's were turned off. Now 1 Vista m/c tells me it has a conflict with another computer on the network with the same IP address. Nothing has changed but this error is brand new. Any ideas?

IP Conflict Preventing Network Access
Do any of your computers use a static IP address? It sounds like the answer
may be yes and you've specified a static IP address that is in the scope of your DHCP server (Linksys router). If this is the case then look at the scope (range of IP addresses) that the Linksys reserves for DHCP and configure the computer with the static IP to use an address outside of that range. With most Linksys routers the static IP should be in the range 192.168.1.2 to 192.168.192.99. The Router itself uses 192.168.1.1 and addresses from 192.168.1.100 to 192.168.1.254 for DHCP. -- Kerry Brown Microsoft MVP - Shell/User http://www.vistahelp.ca "Richard" wrote in message ...

IP Conflict Preventing Network Access
thanks, I went into the linksys console and changed the starting IP address
for the DCHP, that seemed to do the trick, any idea why that occurred, not sure how changing the starting address eliminates the conflict.

IP Conflict Preventing Network Access
It has taken the IP address of whatever computer is using a static IP
address out of the DHCP scope. What was happening was a computer was set with a static IP address. The Linksys router has no idea this has been done. It will happily give another computer that same address and thus the conflict. If you have not set a static IP address on any of your computers then you should investigate this further. If this is a wireless router someone else may be connecting to your network. Did you set a static IP address on any of your computers? -- Kerry Brown Microsoft MVP - Shell/User http://www.vistahelp.ca "Richard" wrote in message ... thanks, I went into the linksys console and changed the starting IP address for the DCHP, that seemed to do the trick, any idea why that occurred, not sure how changing the starting address eliminates the conflict.

IP Conflict Preventing Network Access
I double checked and all PC's are set up for IP address automatically and my
wireless has securtiy enabled, this happened only after we returned from a vacation and all PC's were shut down during this time "Kerry Brown" wrote: It has taken the IP address of whatever computer is using a static IP address out of the DHCP scope.

IP Conflict Preventing Network Access
Most routers have a screen in the administration console where you can see
what computers are connected to the wireless. I'd check to make sure that only yours are connected. I'd also change the router setup password and the wireless security key/password. It may just be that it was a glitch with the DHCP server on the router or one of the computers but I'd take some precautions just in case. -- Kerry Brown Microsoft MVP - Shell/User http://www.vistahelp.ca "Richard" wrote in message news  I double checked and all PC's are set up for IP address automatically and my wireless has securtiy enabled, this happened only after we returned from a vacation and all PC's were shut down during this time "Kerry Brown" wrote: It has taken the IP address of whatever computer is using a static IP address out of the DHCP scope.
