I'm also interested in this topic. My "netstat -a" looked the same as yours last week David.
Last week I ran into an issue where (what I think was..) some security scans on my network for TCP traffic tied up a certain number of ports on my W2k3 master and some NBU processes were unable to interact reliably. Four levels of support were unable to suitably explain the problem to me, and all we ended up doing was throwing in a TCP wait delay into the registry, which "worked" with middling success. The issue has since disappeared (mysteriously) - as I assume whatever activity that was happening over those couple of days has since stopped.

The CLOSE_WAIT entries seemed to hang around for ages, additionally hogging sockets. On the master server everything was plodding along as usual. Q1. can anyone explain why these sockets on the media server do not close fully and hang around for quite sometime ? If indeed the master server has not finalised comms, what (on the master) would be keeping the socket open between the two. Q2. Does anyone know the default setting for the maximum number of simultaneous tcp connections on windows 2000? Q3. If I was to add the registry key to tcp parameters "TcpNumConnections" , what guidelines could I follow to determine the number of connections ? Q4. Not so long ago on the same windows media server I added the registry key to tcp parameters "TcpTimedWaitDelay" in order to clear TIME_WAIT more quickly. Are there any known issues with windows 2000 and tcp connections that I'm not aware off ?
