If you Wireshark you will find Windows performing a network browse for
the "AFS" netbios name. The fact that Explorer is triggering this
search when the "AFS" name is registered with the Multiple UNC Provider
is a bug in Windows. It doesn't happen in all environments and I don't
have a workaround.
Someone with a support contract with Microsoft and a willingness to pay
the root cause investigation expenses is welcome to open a support
incident with them.
