1、Good is good, but better carries it.精益求精，善益求善。Windows防火墻無法啟動(dòng)解決辦法-Windows防火墻無法啟動(dòng)解決辦法在網(wǎng)上下了張系統(tǒng)盤的鏡像，沒發(fā)現(xiàn)病毒便刻成碟，把家里的老機(jī)器重做了系統(tǒng)，發(fā)現(xiàn)很慢，看來盤是不干凈了，待病毒殺盡后，發(fā)現(xiàn)防火墻無法開啟，以前沒碰到過這問題，于是在網(wǎng)上搜索一下解決辦法，整理如下。一、防火墻配置出錯(cuò)開始-運(yùn)行-gpedit.msc這時(shí)打開了組策略在左面分級(jí)展開計(jì)算機(jī)配置-管理模板-網(wǎng)絡(luò)-網(wǎng)絡(luò)連接-Windows防火墻然后在這下面就是組策略強(qiáng)制限制的一些選項(xiàng)找到你所需要的配置定義成啟用再設(shè)置回未配置就可以了(有些軟件更改

2、的注冊(cè)表，有時(shí)在組策略里顯示不出來,可能更改以后組策略里仍然是未配置的,所以要配置一下,再配置回來)二、安全中心被關(guān)閉防火墻啟用的選項(xiàng)變成灰色，無法啟用，并用提示“由于安全考慮，某些設(shè)置由組策略控制”運(yùn)行services.msc打開“服務(wù)”將SecurityCenter設(shè)為自動(dòng)，并且啟用。將WindowsFirewall/InternetConnectionSharing(ICS)設(shè)為自動(dòng)并且啟用。將ApplicationLayerGatewayService設(shè)為自動(dòng)并且啟用。如果仍然不能啟用防火墻，執(zhí)行以下步驟：運(yùn)行regedit.exe打開注冊(cè)表，刪除下面兩項(xiàng)：HKEY_LOCAL_MAC

3、HINESOFTWAREPoliciesMicrosoftWindowsFirewallHKEY_CURRENT_USERSOFTWAREPoliciesMicrosoftWindowsFirewall（至少能找到一項(xiàng)）在服務(wù)中重啟WindowsFirewall/InternetConnectionSharing(ICS)如果繼續(xù)提示“由于安全考慮，某些設(shè)置由組策略控制”，不會(huì)影響使用。三、系統(tǒng)文件丟失由于SharedAccess.reg文件丟失或損壞，SharedAccess.reg文件代表了Windows防火墻服務(wù)。注意：Windows防火墻服務(wù)在WindowsXPsp2替換在早期版本的W

4、indowsXP中Internet連接防火墻(ICF)服務(wù)。要解決此問題，使用下列方法之一。方法1：調(diào)用“安裝APIInstallHinfSection”函數(shù)以安裝Windows防火墻要安裝Windows防火墻,請(qǐng)按照下列步驟：1.單擊開始，單擊運(yùn)行,類型cmd然后單擊確定。2.在命令提示符下，鍵入以下命令行，回車：Rundll32setupapi,InstallHinfSectionNdi-Steelhead132%windir%infnetrass.inf3.重新啟動(dòng)計(jì)算機(jī)4.單擊開始-運(yùn)行（快捷鍵Windows+R），輸入cmd，確定。5.在命令提示符，鍵入以下命令：Netshfirew

5、allreset，回車。6.單擊開始-運(yùn)行，輸入firewall.cpl，回車。7.在Windows防火墻對(duì)話框中單擊On（推薦），確定。方法2：Windows防火墻項(xiàng)添加到注冊(cè)表警告：如果正確修改注冊(cè)表通過注冊(cè)表編輯器或通過其他方法可能發(fā)生Serious問題。這些問題可能需要重新安裝操作系統(tǒng)。Microsoft不能保證能夠解決這些問題。修改注冊(cè)表需要您自擔(dān)風(fēng)險(xiǎn)。要將Windows防火墻項(xiàng)添加到注冊(cè)表,請(qǐng)按照下列步驟操作：1.將以下文本復(fù)制到記事本，然后保存文件為Sharedaccess.reg：WindowsRegistryEditorVersion5.00-HKEY_LOCAL_MACHI
