WIN7下解決因為Windows Time服務無法啟動而造成的時間無法同步問題

     在某些情況下，使用了最佳化工具和清理助手、或者中了木馬等，會造成Windows Time服務無法啟動，從而造成系統時鐘無法與Internet時間伺服器同步。

     關於Windows時鐘無法同步的問題，網路上給出的解決方案基本都是：

     1.運行 cmd 進入命令列，然後鍵入

      w32tm /register<br />正確的響應為：W32Time 成功註冊。 </p><p>

     2.如果上一步正確，用 net start "windows time" 或 net start w32time 啟動服務，也可以進入電腦管理直接啟動Windows Time服務。

     3.如果時間同步是伺服器的地址有問題，可以把下列文字複製，建立一個文字文件另存新檔reg檔案，雙擊匯入註冊表：

      Windows Registry Editor Version 5.00<br />[HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/CurrentVersion/DateTime/Servers]<br />@="6"<br />"1"="time.windows.com"<br />"2"="time.nist.gov"<br />"3"="time-nw.nist.gov"<br />"4"="time-a.nist.gov"<br />"5"="time-b.nist.gov"<br />"6"="210.72.145.44"</p><p>

      或雙擊系統托盤下方的時間，在伺服器位址欄輸入國家授時中心伺服器的IP地址(210.72.145.44)，然後點擊“確定”按鈕儲存下來就行了。

      以上內容來至於互連網絡。

     

      在這裡需要強調並且解決的是，以上第一條命令：w32tm /register 並非總是能成功的，本人就遇到過幾次這種情況。有時候使用w32tm /register 重新註冊時間組件時，會提示拒絕訪問，無法完成註冊，即使是安全模式下也不可行。在這種情況下，如果試圖去啟動Windows Time服務，會提示無法找到模組而啟動失敗。當然，在這種情況下，時鐘同步肯定不能使用。

 

      下面提供該問題的解決方案，該方案是通過維護本人的WIN7系統得出的，不保證所有情況下都能成功（比如system32目錄下的w32time.dll或者w32tm.exe缺失等，此類情況可以通過從其它安裝了相同系統版本的電腦上拷貝對應的w32time.dll和w32tm.exe解決）。

      我們運行 regedit 開啟註冊表，定位到：HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/services/W32Time，可以看到幾個關鍵項目，正確的應該是：

      如果您的電腦有上述問題，那麼會發現註冊表中會少那麼幾項，而且當你試圖將缺失的註冊表添加進去的時候，可能會發現登錄機碼拒絕添加！

      依次在 HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/services/W32Time 的子鍵上點擊右鍵，選擇“許可權”，在彈出的對話方塊中，你可能會看到“組和使用者名稱”一項，只有一個“W32Time”項，問題就出在這裡！可以看到，W32Time的註冊項沒有管理員權限，所以我們進行前面的操作時，都以失敗告終。

      找到了錯誤原因所在，那麼解決起來就簡單了。我們在許可權對話方塊上點擊下面的“進階”按鈕，在彈出的對話方塊中的“許可權”一欄點擊“添加”，再在出來的“選擇使用者或組”對話方塊中點“進階”，又會彈出一個“選擇使用者或組”的對話方塊，點擊中間靠右的“立即尋找”，下面會列出本機上的一些使用者或組，選擇所示中對應的使用者或組，設定相應的許可權（如果不大瞭解，可以勾選所有許可權）。在中勾選“使用可從此對象繼承的許可權替換所有子物件許可權”。

    

     依次按照上面的說明設定好 HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/services/W32Time 及其子項的許可權，然後重新整理註冊表，會發現子項中多出了一些項目，需要注意的是，在子項 HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/services/W32Time/TimeProviders 中，應該有三項：NtpClient、NtpServer和VMICTimeProvider，如果有一個類似於xyz的其它項，請刪除。

     註冊表設定好之後，再依次進行最開始所說的那幾個步驟，即運行 w32tm /register ，然後啟動Windows Time 服務。如果仍然無法成功，請重新啟動電腦，並在電腦完全啟動後，再運行上述命令。

      一般情況下，上述辦法可解決Windows Time 時間同步問題。
