DNS - Absolutely Not. He is using IP addresses and not DNS references. he has a box with a 3com ethernet interface in it whose last three octets of the MAC address of the ethernet controller are 99:f8:35. My PS2 is not handy, but there is usually a sticker on these boxes that shows the MAC (ethernet) address of the interface. Check your PS2 and see if you can match up the MAC address. The LAST ARP request from 192.168.0.1 indicates that your PS2 is this MAC address. with The apparent source of the ARP request for 192.168.0.1 being your PS2 The request for 193.168.0.1 can only have originated from the PS2. Therefore you either have 1. A misconfigured Gateway Entry in your PS2 IP setup where you made a typo and put 193 instead of 192. Most Likely scenario. Recheck this entry and correct or reenter. power cycle the PS2. It might only read EEPROM values on boot. 2. A stuck BIT in the PS2 hardware that is pushing out 193 instead of 192. With nothing else appearing to be corrupted here, the stuck bit would have to be only in the stored location of the 192 value and hence it should also be displayed as 193 when you look at the gateway entry on the PS2. The only other logical place would be if the 3COM driver/hardware also copies the eeprom value to local ENET controller memory and that is where the bit is stuck on. You would have to replace the Enet controller in the PS2 to fix this issue if it is located there. > > On Wed, 2003-11-19 at 18:55, Jeff wrote: > > Guys, > > > > I've got a major prob on my LAN.
