    If you install WireShark and watch the network traffic on the
    machine I suspect that you will find that the delay is being caused
    by the Microsoft Lan Manager (SMB) network provider.=C2=A0 It issues =
an
    NBNS Name query for "AFS &lt;20&gt;" and then a DNS query for
    "afs.&lt;search-domain&gt;".=C2=A0 If it gets a response to either it=

    then attempts an ICMP ping to the resulting address and an NBNS
    NBSTAT query.=C2=A0 Only after the LanMan provider times out does it
    report failure and it retries this sequence for every request.<br>
    <br>
    Adding a fake "AFS" entry to the
    %windir%\system32\drivers\etc\LMHOSTS file prevents the NBNS Name
    queries for "AFS &lt;20&gt;" from being sent.=C2=A0=C2=A0 At the pres=
ent time,
    the OpenAFS installer only creates such an entry as part of
    installing the Microsoft Loopback Adapter which is not installed by
    default now that the afs redirector driver is available.<br>
