Sql server FreeTDS-tsql连接，isql失败

我正在尝试连接到主机（windows xp、sql server 05）上的数据库。我的客户机是Ubuntu 10.04。我可以用tsql连接和执行命令，但isql失败了。下面是我的配置文件和错误消息

freetds.conf

text size = 64512

[SQLEXPRESS]
host = 192.168.163.1
port = 1433
tds version = 7.0

odbcinst.ini

Setup           = /usr/lib/odbc/libtdsS.so
CPTimeout       =
CPReuse         =

odbc.ini

[SQLEXPRESS]
Driver          = FreeTDS

UID         = sa
PWD         = test1234

tsql：

isql：

问题在于odbc.ini中的这一行

Servername=192.168.163.1

应该是SQLEXPRESS，我认为它指向在freetds.conf中配置的服务器的名称。您好，我已经设置了与SQLEXPRESS相同的服务器名称，但仍然得到了相同的错误。
