So I was just doing some server side troubleshooting on the network I noticed that 1 of the servers sends all packets with the IP level checksum set to 0. It caught my eye because in my wireshark capture, all packets (no matter what application level protocol, tcp/udp) have the IP layer were marked black (default color setting for wireshark). The server has been working fine, there are no issues with it in terms of network communication, it just caught my eye and seems to be bugging me.
Anyone have any ideas what settings to check on this server? Its a Windows 2003 Standard edition server.
