    Just a quick question. Has anyone seen arp issues between Windows 7 and XP/Vista clients?

    I have the Windows 7 RC running on one machine and Vista and XP running on other machines. I found that even when I turned off the firewall on each of the systems I was unable to ping to or from the W7 PC.

    After some digging around I found I was not seeing any ARP responses on W7 for my other clients and vice versa. For information I could ping my wireless router. After adding some static arp entries I found I was able to ping between the machines and share network resources.

    I am planning to do a packet capture when I get the right software loaded but I was wondering if anyone has seen this issue and knows of a permanent fix as I run DHCP and static arps will drive me mad!
