注册或者新建账套时，系统提示“不能创建SSPI上下文”?

这个是由于SQLServer使用Windows认证方式，并且数据库服务器使用IP地址，不能通过IP地址解析机器名引起的，解决方法如下：

       1）使用机器名而不是IP地址

       2）在中间层的Hosts文件中加入数据库服务器的IP地址和机器名

Hosts文件的路径:
C:\WINNT\system32\drivers\etc

Hosts文件内容:

# Copyright (c) 1993-1999 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
