Warning: mssql_connect() [function.mssql-connect]: Unable to connect to server，下面我们来介绍此问题的解决办法。
我有一台服务器win2003SP1+sqlserver2000（已打上SP4补丁）
PHP远程连接sql2000 连接失败是什么情况？
1、服务器本机测试可连接！
2、在自己的电脑上用查询分析器也可以连上！
服务器上的1433端口在监听
sql2000的用户名、密码没错，权限也没问题！
ntwdblib.dll 版本是2000.80.194.0 、php、system32目录下的都已近更新
ntwdblib.dll和php_mssql.dll 都已经复制到system32目录下
extension=php_mssql.dll 前面的分号已近去掉
服务器环境是wamp，更改好之后有重启过的！
试过很多方法都还是连接不上，网上的方法基本上都是过了！实在没有办法啦！求救啊！
下面给出代码和失败提示！
代码：
| 代码如下 | 复制代码 |
| 1、$conn=mssql_connect("121.10.108.112",'m123','m123') or die('连接不上'); 2、$conn=mssql_connect("121.10.108.112:1433",'m123','m123') or die('不上'); 3、$conn=mssql_connect("121.10.108.112,1433",'m123','m123') or die('数据库连接不上'); |
|
3种代码都试过
失败提示：
Warning: mssql_connect() [.mssql-connect]: Unable to connect to server: 121.10.108.112 in C:wampwwwtest.php on line 9
数据库连接不上
解决办法
统是:
win2003+mssql2000+php5.23
实现方法
php目录下有没有ntwdblib.dll有没有这个文件?ntwdblib.dll是客户连接库,如果有查看一下版本号是多少,一般会是7.0的,这个只能与mssq 7.0进行连接,我们为了能与我们现数据库教程版本相同就把mssql下的ntwdblib.dll拷贝到你php 所在的目录替换那个7.0的,重起iis就ok了
