    We have approx 16 users (about 8 active at any one time) connected to an SBS
    2003 (std) server.

    I have just run a Netstat -ano command, which reveals 30 or 40 plus TCP
    connections in the CLOSE_WAIT state.
    These are of the form:

    xxxxx is a different high-numbered port for each line.
    3120 is the Process ID which relates to mad.exe, whilst I gather port 389
    relates to LDAP.

    Whats is going on here. Why are there so many connections in this state

  2. Hi Roger,

    mad.exe is one of the primary Exchange processes, and it routinely talks to
    Active Directory (which uses port 389) for various reasons.
    This is normal behavior, and isn't anything to be worried about.
