出现过很多次恢复固件时出现1600错误，也找了很多办法，还是解决不了。终于在网上发现一个方法可以完美解决1600错误
个人感觉1600错误就是因为杀毒软件或者360等管理软件禁用了三个系统服务项：telnet ,messenger ,terminal services三个服务
XP系统可以在服务里开启这三个服务，但win7里面没有telnet ,messenger ,terminal services三个服务
以下是解决办法：
Terminal Services在Windows 7中变成了Remote Desktop Services
Telnet需要在控制面板中安装, 具体:
控制面板->程序与功能->左边"打开或关闭Windows功能"-选上"Telnet Client" 然后OK
Messenger在Windows 7/Server 2008 R2里都去掉了
按步骤来就可以了，之后重启，最好把hosts恢复一下
下面给出WIN7的HOSTS
# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host
# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost
