如何调用已经建立的ADSL拨号连接？
我的系统是XP，已经建立了一个“ADSL”的拨号连接，请问如何才能在delphi中调用它进行拨号上网呢？我在网上找到一个这样的方法：
winexec('rundll32.exe rnaui.dll,RnaDial ADSL',SW_SHOWNORMAL);
不过我按这种方法编程后发现运行时提示：
加载rnaui.dll时出错 找不到指定的模块
在windows的运行中直接输入rundll32.exe rnaui.dll,RnaDial adsl也是同样的错误，请问我应该怎么办啊？

使用rasdial.exe试试看，例有一个ADSL连接名叫'ADSL'并保存了用户名和密码，就使用：
rasdial adsl
===========================================================
rasdial entryname [username [password|*]] [/DOMAIN:domain]
[/PHONE:phonenumber] [/CALLBACK:callbacknumber]
[/PHONEBOOK:phonebookfile] [/PREFIXSUFFIX]
rasdial [entryname] /DISCONNECT

可惜找不到ADSLDPC.DLL的相关文档。Top

在CMD中输入：rasdial adsl后出现（ADSL保存了密码）：
＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝
正在连接到 ADSL...
正在验证用户名及密码...
远程访问错误 691 由于域上的用户名和/或密码无效而拒绝访问。
若需此错误的详细说明:
请在帮助中键入“hh netcfg.chm”
单击“疑难解答”，选择“错误信息”，然后键入 “ 691”Top

即使你保存了密码，也需要这样调用的：
rasdial adsl 用户名 密码Top
