閱讀這篇有趣的文章後： http://www.codeproject.com/Articles/16541/Create-your-Proxy-DLLs-automatically是否有可能用代理dll替換系統dll？
我決定嘗試和創造純科研目的的代理DLL。 :-)
我做的所有步驟上ws2_32.dll這是我已經得到了代碼：

HINSTANCE hL = 0;
FARPROC p[182] = {0};
BOOL WINAPI DllMain(HINSTANCE hInst,DWORD reason,LPVOID)
{
//to get indication whether we were loaded
FILE* f;
fopen_s(&f, "C:\\load.txt", "a+");
fclose(f);
if (reason == DLL_PROCESS_ATTACH)

我編譯它（與.def文件），並得到了一個新的proxy.dll文件。 :-)
到目前爲止這麼好。現在，在我的VBox win7 x64上，我將原始的ws2_32.dll更名爲ws2_32_.dll，將我的proxy.dll放入C:\\Windows\\System32\\，並將其更名爲ws2_32.dll。由於premmisions問題，我用live-cd linux做了所有這些。
正如你可以看到代理加載ws2_32_.dll所以我們應該沒問題。 但是當系統從引導程序返回時，每個程序使用ws2_32.dll都會引發錯誤，並且從不會創建文件C:\\load.txt。
我不知道文章中的人做了什麼工作。我讀過谷歌，你需要放置（和重命名）proxy.dll在與你想運行代理DLL的程序相同的目錄中，但我正在尋找一個全局解決方案。
也許這是一個校驗和的問題？我讀過微軟在系統PE上使用一些祕密校驗和。
謝謝，gfgqtmakia。
支持的方法是通過分層服務提供程序。 –
@RaymondChen Thx進行評論。 LSP只適用於Winsock，不是嗎？如果它是'user32.dll'而不是'ws2_32.dll'會怎麼樣？ – assafmo
是不是並排和一些Windows「已知的DLL」保護將阻止這樣的嘗試？ –
