&lt;P&gt;Windows Server 2008 è stato rilasciato in RTM a Febbraio 2008 e includeva la versione beta di Hyper-V, mentre la &lt;A href="http://www.microsoft.com/italy/info/annunci/server/generale/hyperv.mspx" target=_blank mce_href="http://www.microsoft.com/italy/info/annunci/server/generale/hyperv.mspx"&gt;versione finale di Hyper-V è stata resa disponibile a Giugno 2008&lt;/A&gt;.&lt;/P&gt;
&lt;P&gt;Per aggiornare la copia di Hyper-V presente sul server basta semplicemente installare la &lt;A href="http://www.microsoft.com/downloads/details.aspx?FamilyId=6F69D661-5B91-4E5E-A6C0-210E629E1C42&amp;amp;displaylang=en" target=_blank mce_href="http://www.microsoft.com/downloads/details.aspx?FamilyId=6F69D661-5B91-4E5E-A6C0-210E629E1C42&amp;amp;displaylang=en"&gt;KB 950050 - Hyper-V Update for Windows Server 2008&lt;/A&gt;&lt;/P&gt;
&lt;P&gt;I dettagli di questo problema sono disponibili nel seguente articolo:&lt;BR&gt;&lt;STRONG&gt;KB 967902&lt;BR&gt;&lt;/STRONG&gt;You cannot connect to a virtual machine when the Windows Server 2008 Hyper-V VMMS certificate has expired&lt;BR&gt;&lt;A href="http://support.microsoft.com/kb/967902"&gt;http://support.microsoft.com/kb/967902&lt;/A&gt;&lt;/P&gt;
&lt;P&gt;Ulteriori informazioni sono disponibili nel &lt;A href="http://blogs.technet.com/windowsserver/archive/2009/03/02/Hyper_2D00_V-certificate-expiration-and-resolution.aspx" mce_href="http://blogs.technet.com/windowsserver/archive/2009/03/02/Hyper_2D00_V-certificate-expiration-and-resolution.aspx"&gt;Windows Server Division WebLog&lt;/A&gt;.&lt;/P&gt;
&lt;P&gt;L'hotfix KB 967902 è stata rilasciata tramite Windows Update.&lt;/P&gt;
&lt;H3&gt;Scenario&lt;/H3&gt;
&lt;P&gt;Chi ha installato Windows Server 2008 a partire dal 27 Febbraio 2008, giorno del rilascio ufficiale, potrebbe ricevere i messaggi di errore indicati nella sezione Sintomi.&lt;/P&gt;
&lt;P&gt;Questo problema accade perché il servizio Virtual Machine Management (VMMS) di Hyper-V ha un certificato con lo scopo di “Server Authentication” che è utilizzato quando ci si collega ad una macchina virtuale. Di default questo certificato ha validità di 1 anno e potrebbe essere scaduto.&lt;/P&gt;
&lt;H3&gt;Sintomi&lt;/H3&gt;
&lt;P&gt;Dopo un anno dall’installazione del ruolo &lt;A href="http://technet.microsoft.com/it-it/magazine/2008.10.hyperv.aspx" target=_blank mce_href="http://technet.microsoft.com/it-it/magazine/2008.10.hyperv.aspx"&gt;“Hyper-V” in Windows Server 2008&lt;/A&gt;, se si tenta di collegarsi alle macchine virtuali, si può riceve il seguente errore:&lt;/P&gt;
&lt;BLOCKQUOTE&gt;
&lt;P&gt;"Cannot connect to the virtual machine because the authentication certificate is expired or invalid. Would you like to try connecting again?"&lt;/P&gt;&lt;/BLOCKQUOTE&gt;
&lt;P&gt;Oppure se si prova ad avviare una macchina virtuale, il child non parte e sono visualizzati i seguenti messaggi:&lt;/P&gt;
&lt;BLOCKQUOTE&gt;
&lt;P&gt;‘VMName’ failed to initialize.&lt;/P&gt;
&lt;P&gt;Could not initialize machine remoting system. Error: ‘Unspecified error’ (0x80004005).&lt;/P&gt;
&lt;P&gt;Could not find a usable certificate. Error: ‘Unspecified error’ (0x80004005)&lt;/P&gt;&lt;/BLOCKQUOTE&gt;
&lt;H3&gt;Aggiornamento automatico&lt;/H3&gt;
&lt;P&gt;E’ previsto un aggiornamento ufficiale il 2 Marzo 2009 e sarà successivamente rilasciato tramite Windows Update a partire dal 24 Marzo 2009.&lt;/P&gt;
&lt;P&gt;Questo problema è risolto in Windows Server 2008 SP2 e Windows 7.&lt;/P&gt;
&lt;H3&gt;Workaround&lt;/H3&gt;
&lt;P&gt;In attesa dell’aggiornamento ufficiale, di seguito vi riporto i passi per ottenere un nuovo certificato:&lt;/P&gt;
&lt;OL&gt;
&lt;LI&gt;Aprire “Services.msc” da &lt;B&gt;Start&lt;/B&gt; – &lt;B&gt;Run&lt;/B&gt; o tramite “Computer Management” &lt;BR&gt;&lt;A href="http://blogs.technet.com/blogfiles/itasupport/WindowsLiveWriter/HyperVImpossibilecollegarsialleMacchineV_CF8E/image_20.png" mce_href="http://blogs.technet.com/blogfiles/itasupport/WindowsLiveWriter/HyperVImpossibilecollegarsialleMacchineV_CF8E/image_20.png"&gt;&lt;IMG style="BORDER-BOTTOM: 0px; BORDER-LEFT: 0px; DISPLAY: block; FLOAT: none; MARGIN-LEFT: auto; BORDER-TOP: 0px; MARGIN-RIGHT: auto; BORDER-RIGHT: 0px" title=image border=0 alt=image src="http://blogs.technet.com/blogfiles/itasupport/WindowsLiveWriter/HyperVImpossibilecollegarsialleMacchineV_CF8E/image_thumb_9.png" width=407 height=203 mce_src="http://blogs.technet.com/blogfiles/itasupport/WindowsLiveWriter/HyperVImpossibilecollegarsialleMacchineV_CF8E/image_thumb_9.png"&gt;&lt;/A&gt; &lt;/LI&gt;
&lt;LI&gt;Arrestare il servizio &lt;STRONG&gt;Hyper-V Virtual Machine Management&lt;/STRONG&gt;&amp;nbsp; &lt;BR&gt;&lt;A href="http://blogs.technet.com/blogfiles/itasupport/WindowsLiveWriter/HyperVImpossibilecollegarsialleMacchineV_CF8E/image_24.png" mce_href="http://blogs.technet.com/blogfiles/itasupport/WindowsLiveWriter/HyperVImpossibilecollegarsialleMacchineV_CF8E/image_24.png"&gt;&lt;IMG style="BORDER-BOTTOM: 0px; BORDER-LEFT: 0px; DISPLAY: block; FLOAT: none; MARGIN-LEFT: auto; BORDER-TOP: 0px; MARGIN-RIGHT: auto; BORDER-RIGHT: 0px" title=image border=0 alt=image src="http://blogs.technet.com/blogfiles/itasupport/WindowsLiveWriter/HyperVImpossibilecollegarsialleMacchineV_CF8E/image_thumb_11.png" width=881 height=296 mce_src="http://blogs.technet.com/blogfiles/itasupport/WindowsLiveWriter/HyperVImpossibilecollegarsialleMacchineV_CF8E/image_thumb_11.png"&gt;&lt;/A&gt; &lt;/LI&gt;
&lt;LI&gt;Aprire una nuova &lt;STRONG&gt;MMC&lt;/STRONG&gt; vuota da &lt;B&gt;Start &lt;/B&gt;– &lt;B&gt;Run&lt;/B&gt; &lt;BR&gt;&lt;A href="http://blogs.technet.com/blogfiles/itasupport/WindowsLiveWriter/HyperVImpossibilecollegarsialleMacchineV_CF8E/image_14.png" mce_href="http://blogs.technet.com/blogfiles/itasupport/WindowsLiveWriter/HyperVImpossibilecollegarsialleMacchineV_CF8E/image_14.png"&gt;&lt;IMG style="BORDER-BOTTOM: 0px; BORDER-LEFT: 0px; DISPLAY: block; FLOAT: none; MARGIN-LEFT: auto; BORDER-TOP: 0px; MARGIN-RIGHT: auto; BORDER-RIGHT: 0px" title=image border=0 alt=image src="http://blogs.technet.com/blogfiles/itasupport/WindowsLiveWriter/HyperVImpossibilecollegarsialleMacchineV_CF8E/image_thumb_6.png" width=407 height=203 mce_src="http://blogs.technet.com/blogfiles/itasupport/WindowsLiveWriter/HyperVImpossibilecollegarsialleMacchineV_CF8E/image_thumb_6.png"&gt;&lt;/A&gt; &lt;/LI&gt;
&lt;LI&gt;In &lt;B&gt;Console1&lt;/B&gt; selezionare il menù &lt;B&gt;File&lt;/B&gt; – &lt;B&gt;Add/Remove Snap-In&lt;/B&gt; &lt;BR&gt;&lt;A href="http://blogs.technet.com/blogfiles/itasupport/WindowsLiveWriter/HyperVImpossibilecollegarsialleMacchineV_CF8E/image_18.png" mce_href="http://blogs.technet.com/blogfiles/itasupport/WindowsLiveWriter/HyperVImpossibilecollegarsialleMacchineV_CF8E/image_18.png"&gt;&lt;IMG style="BORDER-BOTTOM: 0px; BORDER-LEFT: 0px; DISPLAY: block; FLOAT: none; MARGIN-LEFT: auto; BORDER-TOP: 0px; MARGIN-RIGHT: auto; BORDER-RIGHT: 0px" title=image border=0 alt=image src="http://blogs.technet.com/blogfiles/itasupport/WindowsLiveWriter/HyperVImpossibilecollegarsialleMacchineV_CF8E/image_thumb_8.png" width=297 height=279 mce_src="http://blogs.technet.com/blogfiles/itasupport/WindowsLiveWriter/HyperVImpossibilecollegarsialleMacchineV_CF8E/image_thumb_8.png"&gt;&lt;/A&gt; &lt;/LI&gt;
&lt;LI&gt;Nella finestra &lt;B&gt;Available snap-ins&lt;/B&gt; selezionare &lt;B&gt;Certificates&lt;/B&gt; e cliccare &lt;B&gt;Add&lt;/B&gt; &lt;BR&gt;&lt;A href="http://blogs.technet.com/blogfiles/itasupport/WindowsLiveWriter/HyperVImpossibilecollegarsialleMacchineV_CF8E/image_16.png" mce_href="http://blogs.technet.com/blogfiles/itasupport/WindowsLiveWriter/HyperVImpossibilecollegarsialleMacchineV_CF8E/image_16.png"&gt;&lt;IMG style="BORDER-BOTTOM: 0px; BORDER-LEFT: 0px; DISPLAY: block; FLOAT: none; MARGIN-LEFT: auto; BORDER-TOP: 0px; MARGIN-RIGHT: auto; BORDER-RIGHT: 0px" title=image border=0 alt=image src="http://blogs.technet.com/blogfiles/itasupport/WindowsLiveWriter/HyperVImpossibilecollegarsialleMacchineV_CF8E/image_thumb_7.png" width=682 height=474 mce_src="http://blogs.technet.com/blogfiles/itasupport/WindowsLiveWriter/HyperVImpossibilecollegarsialleMacchineV_CF8E/image_thumb_7.png"&gt;&lt;/A&gt; &lt;/LI&gt;

&lt;LI&gt;Nella schermata &lt;B&gt;Select the Computer...&lt;/B&gt; selezionare &lt;B&gt;Local computer&lt;/B&gt; e cliccare &lt;B&gt;Next&lt;/B&gt; &lt;BR&gt;&lt;A href="http://blogs.technet.com/blogfiles/itasupport/WindowsLiveWriter/HyperVImpossibilecollegarsialleMacchineV_CF8E/image_8.png" mce_href="http://blogs.technet.com/blogfiles/itasupport/WindowsLiveWriter/HyperVImpossibilecollegarsialleMacchineV_CF8E/image_8.png"&gt;&lt;IMG style="BORDER-RIGHT-WIDTH: 0px; DISPLAY: block; FLOAT: none; BORDER-TOP-WIDTH: 0px; BORDER-BOTTOM-WIDTH: 0px; MARGIN-LEFT: auto; BORDER-LEFT-WIDTH: 0px; MARGIN-RIGHT: auto" title=image border=0 alt=image src="http://blogs.technet.com/blogfiles/itasupport/WindowsLiveWriter/HyperVImpossibilecollegarsialleMacchineV_CF8E/image_thumb_3.png" width=528 height=385 mce_src="http://blogs.technet.com/blogfiles/itasupport/WindowsLiveWriter/HyperVImpossibilecollegarsialleMacchineV_CF8E/image_thumb_3.png"&gt;&lt;/A&gt; &lt;/LI&gt;
&lt;LI&gt;Nella lista &lt;B&gt;Service account&lt;/B&gt; selezionare il servizio &lt;B&gt;Hyper-V Virtual Machine Management&lt;/B&gt; e cliccare &lt;STRONG&gt;Finish&lt;/STRONG&gt; e poi &lt;B&gt;OK&lt;/B&gt; &lt;BR&gt;&lt;A href="http://blogs.technet.com/blogfiles/itasupport/WindowsLiveWriter/HyperVImpossibilecollegarsialleMacchineV_CF8E/image_10.png" mce_href="http://blogs.technet.com/blogfiles/itasupport/WindowsLiveWriter/HyperVImpossibilecollegarsialleMacchineV_CF8E/image_10.png"&gt;&lt;IMG style="BORDER-RIGHT-WIDTH: 0px; DISPLAY: block; FLOAT: none; BORDER-TOP-WIDTH: 0px; BORDER-BOTTOM-WIDTH: 0px; MARGIN-LEFT: auto; BORDER-LEFT-WIDTH: 0px; MARGIN-RIGHT: auto" title=image border=0 alt=image src="http://blogs.technet.com/blogfiles/itasupport/WindowsLiveWriter/HyperVImpossibilecollegarsialleMacchineV_CF8E/image_thumb_4.png" width=528 height=385 mce_src="http://blogs.technet.com/blogfiles/itasupport/WindowsLiveWriter/HyperVImpossibilecollegarsialleMacchineV_CF8E/image_thumb_4.png"&gt;&lt;/A&gt; &lt;/LI&gt;
&lt;LI&gt;Ritornare in Console1, nel pannello di sinistra espandere &lt;B&gt;Certificates&lt;/B&gt;, &lt;B&gt;vmms\Personal&lt;/B&gt; e selezionare &lt;B&gt;Certificates&lt;/B&gt; &lt;A href="http://blogs.technet.com/blogfiles/itasupport/WindowsLiveWriter/HyperVImpossibilecollegarsialleMacchineV_CF8E/image_12.png" mce_href="http://blogs.technet.com/blogfiles/itasupport/WindowsLiveWriter/HyperVImpossibilecollegarsialleMacchineV_CF8E/image_12.png"&gt;&lt;BR&gt;&lt;IMG style="BORDER-RIGHT-WIDTH: 0px; DISPLAY: block; FLOAT: none; BORDER-TOP-WIDTH: 0px; BORDER-BOTTOM-WIDTH: 0px; MARGIN-LEFT: auto; BORDER-LEFT-WIDTH: 0px; MARGIN-RIGHT: auto" title=image border=0 alt=image src="http://blogs.technet.com/blogfiles/itasupport/WindowsLiveWriter/HyperVImpossibilecollegarsialleMacchineV_CF8E/image_thumb_5.png" width=940 height=301 mce_src="http://blogs.technet.com/blogfiles/itasupport/WindowsLiveWriter/HyperVImpossibilecollegarsialleMacchineV_CF8E/image_thumb_5.png"&gt;&lt;/A&gt; &lt;/LI&gt;
&lt;LI&gt;Nel pannello di destra, fare doppio click sul certificato con il nome macchina e seleziona la scheda &lt;B&gt;General&lt;/B&gt;&lt;BR&gt;&lt;A href="http://blogs.technet.com/blogfiles/itasupport/WindowsLiveWriter/HyperVImpossibilecollegarsialleMacchineV_CF8E/image_4.png" mce_href="http://blogs.technet.com/blogfiles/itasupport/WindowsLiveWriter/HyperVImpossibilecollegarsialleMacchineV_CF8E/image_4.png"&gt;&lt;IMG style="BORDER-RIGHT-WIDTH: 0px; DISPLAY: block; FLOAT: none; BORDER-TOP-WIDTH: 0px; BORDER-BOTTOM-WIDTH: 0px; MARGIN-LEFT: auto; BORDER-LEFT-WIDTH: 0px; MARGIN-RIGHT: auto" title=image border=0 alt=image src="http://blogs.technet.com/blogfiles/itasupport/WindowsLiveWriter/HyperVImpossibilecollegarsialleMacchineV_CF8E/image_thumb_1.png" width=414 height=513 mce_src="http://blogs.technet.com/blogfiles/itasupport/WindowsLiveWriter/HyperVImpossibilecollegarsialleMacchineV_CF8E/image_thumb_1.png"&gt;&lt;/A&gt; &lt;/LI&gt;
&lt;LI&gt;Verificare che il certificato sia scaduto: &lt;STRONG&gt;Valid from xxx to xxx&lt;/STRONG&gt;.&lt;BR&gt;In caso sia effettivamente&amp;nbsp;scaduto, &lt;STRONG&gt;spegnere &lt;/STRONG&gt;tutte le macchine virtuali &lt;/LI&gt;
&lt;LI&gt;Ritornare alla console “Services.msc” e riavviare il servizio &lt;B&gt;Hyper-V Virtual Machine Management&lt;/B&gt;.&lt;BR&gt;Una volta che il servizio è stato riavviato, ritornare in Console1 e un nuovo certificato valido dovrebbe essere stato rilasciato. &lt;/LI&gt;
&lt;LI&gt;Riavviare le macchine virtuali e il collegamento dovrebbe funzionare correttamente.&lt;/LI&gt;&lt;/OL&gt;
