Windows腳本可以調用MSWinsock控件獲得比較強大的網絡訪問能力，但那個106KB的mswinsck.ocx(V6.0.89.88)不是系統自帶的，這使得該控件的實用性大打折扣。而且，腳本要調用MSWinsock還必須克服一個困難。
以"MSWinsock"爲關鍵字，使用百度搜索網頁，可以獲得至少3個VBS調用MSWinsock控件的例子：獲取本機IP、端口掃描和發在"黑防"的《VBS+MSWinsock打造靈巧UDP後門》。但是，當你下載並註冊mswinsck.ocx，然後嘗試那些代碼時，卻會得到一個"類別未授權使用(Class is not licensed for use)"錯誤，錯誤號0x80040112。那些代碼的作者似乎都以爲MSWinsock和一般的控件一樣，只要用regsvr32註冊就能正常使用了，沒有實際測試它的可移植性。而轉貼文章的人，更不會關心內容是否可靠，一味地複製粘貼而已。結果，網上所有關於VBS調用MSWinsock的例子都是"空中樓閣"，沒有一個跑的起來。國內如此，國外也一樣。所有對該控件無法使用的質疑，都被人以"需要註冊"爲理由打發了。當然，也有了解"真相"的人，但其給出的解決方案竟然是用VB重新寫個ocx封裝MSWinsock，這實在是@#$%^&!。
那麼，"真相"究竟是什麼？搜索"類別未授權使用"和錯誤號，這是個好主意，但結果不理想。我們需要逆向思考，爲什麼原作者不會遇到錯誤。答案是原作者的mswinsck.ocx不是單獨註冊的，而是隨VB一起安裝的。其中的差別在於，後者會安裝VB控件的設計時許可證(design-time license)。ActiveX控件的License有兩種：設計時(design-time)和運行時(run-time)。當編譯調用了某個控件的exe/dll/ocx時，編譯器會自動加入該控件的運行時許可證，所以"重新寫個ocx封裝MSWinsock"這個辦法可行。使用腳本直接調用MSWinsock時沒有運行時許可證，這時腳本宿主會嘗試在註冊表中獲取設計時許可證，單獨註冊的MSWinsock沒有相應的設計時許可證，所以就出錯了。
在VS.NET安裝盤裏有VB6控件的授權密鑰(/Extras/VB6 Controls/VB6Controls.reg)，導入註冊表後就能正常使用包括MSWinsock在內的VB6控件了。
