Network traffic to/from MVP

[navels]

I have been using Network Monitor (Microsoft's latest version of netmon) to troubleshoot a problem on my home network. Here is a capture showing traffic between my XP box that runs Sage server (192.168.1.2) and my wired MVP (192.168.1.100):

159 38.000000 192.168.1.2 192.168.1.100 TCP TCP: Flags=...PA..., SrcPort=31099, DstPort=4126, Len=8
160 38.000000 192.168.1.2 192.168.1.100 TCP TCP: Flags=...PA..., SrcPort=31099, DstPort=4126, Len=88
161 38.000000 192.168.1.2 192.168.1.100 TCP TCP: Flags=...PA..., SrcPort=31099, DstPort=4126, Len=8
162 38.000976 192.168.1.100 192.168.1.2 TCP TCP: Flags=....A..., SrcPort=4126, DstPort=31099, Len=0
163 38.000976 192.168.1.100 192.168.1.2 TCP TCP: Flags=....A..., SrcPort=4126, DstPort=31099, Len=0
164 38.000976 192.168.1.100 192.168.1.2 TCP TCP: Flags=....A..., SrcPort=4126, DstPort=31099, Len=0
165 38.083008 192.168.1.100 192.168.1.2 TCP TCP: Flags=...PA..., SrcPort=4126, DstPort=31099, Len=16
166 38.083008 192.168.1.100 192.168.1.2 TCP TCP: Flags=...PA..., SrcPort=4126, DstPort=31099, Len=4
167 38.083008 192.168.1.2 192.168.1.100 TCP TCP: Flags=....A..., SrcPort=31099, DstPort=4126, Len=0

This repeats roughly every two seconds. Is all this chatter really necessary, or does it indicate some kind of misconfiguration? I was not using the server or the MVP when the above was captured (nothing recording, playing, not using the remote, etc.).

Thanks,
