在微軟的技術論壇看到一篇類似的討論，看來是在安裝Windows時，管理人員就已經將此服務刪除了，要恢復此服務的話，可以試試微軟MVP Alex提供的方法：

1.確認電腦中已經存在下列的系統元件：
NetBIOS Interface
Plug and Play
Remote Procedure Call (RPC)
Workstation

2.嘗試將下面的內容複製貼到記事本（NotePad），並將其存檔成 Messenger.reg，然後執行該檔案，開啟「服務」，檢視其是否出現於其內：
檢視原始檔複製到剪貼簿列印關於

please explain: what is 不見蛋了嗎??...

你說的不見是指在Service裡面沒有嗎，檢查一下Registry
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Messenger
是不是沒有這個項目，可以從別台匯入這個機碼，應該就會有了

Messenger(信差服務)，這服務自從以前被駭客入侵亂發訊息之後，微軟預設成「不開啟」啦，用到的機會～不多吧！？除非 區域網路內部作為訊息發佈，否則真的很少人用呢！

有啊~ 我有看過不見的~ 目前網路上流傳的很多自動安裝版本的Windows軟體~
常常會有在製作的時候就把這項服務移除掉了~

所以安裝完後就自然而然沒有這個東西了啊~

如果想要在裝回來~ 那就拿原版的 XP 再重灌一次吧~
用別人做出來的東西常常會少東少西的~ 最好的方法還是自己做^^"

是同一台電腦裡的服務突然不見了嗎？
還是新灌的呢？
作業系統為何？
Vista已經將這個功能拿掉了喔～

從新安裝試試看.或者將一些比較沒有用的程式殺掉看看.(參考題).WATER.0911115854.( macosorawater@pchome.com.tw ). http://www.macosorawater.pchome.com.tw .小禮.Thanks. 11111111 .
