ADO连接sql 2000问题

    str_serversIP = "192.168.1.222"
    str_DBConnectString = "driver={sql server};server =" & str_serversIP & ";uid=sa;pwd=123456;Database=STX"
    
    Set rs = New ADODB.Recordset
    Set conn = New ADODB.Connection
    conn.ConnectionString = str_DBConnectString
    conn.ConnectionTimeout = 50
    conn.Open
    Set rs.ActiveConnection = conn
    rs.CursorType = adOpenDynamic

总是提示如下：
实时错误，“-2147467259（80004005）”
没有提供任何DSN or SERVER 关键字

如果改成，就没事：

   Set rs = New ADODB.Recordset
    Set conn = New ADODB.Connection     conn.ConnectionString= "driver=sqlserver};server=192.168.1.222;uid=sa;pwd=123456;Database=STX"
    conn.ConnectionTimeout = 50
    conn.Open
    Set rs.ActiveConnection = conn
    rs.CursorType = adOpenDynamic

请问怎么回事。 sql?server
[解决办法]

str_serversIP = "192.168.1.222"    str_DBConnectString = "driver={sql server};server =" & str_serversIP & ";uid=sa;pwd=123456;Database=STX"

'错误是在server和等号之间多了一个空格，去掉空格就没有错误了。
str_serversIP = "192.168.1.222"    str_DBConnectString = "driver={sql server};server=" & str_serversIP & ";uid=sa;pwd=123456;Database=STX"
