Negli eventi di sistema vi compare il seguente errore nel caso abbiate installato il servizio Windows Server Update Services di Microsoft per l\u2019aggiornamento dei client win 2000 SP4 e win Xp SP2:<\/p>\n

Event Type: Error
\nEvent Source: Windows Server Update Services
\nEvent Category: Update Services Service
\nEvent ID: 506
\nDate: 05\/07\/2005
\nTime: 0.32.15
\nUser: N\/A
\nComputer: SERVER01
\nDescription:
\nThe SelfUpdate Tree is not working\u00b7\u2002 Clients may not be able to update to
\nthe latest WUA client software and communicate with the WSUS Server<\/p>\n

La soluzione al problema potrebbero essere molteplici e difficili da individuare, in quanto questo tipo di codice si presenta pi\u00f9 volte per tipologie diverse. Solitamente l\u2019errore pi\u00f9 comune \u00e8 installare il servizio Wsus su una porta alternativa alla 80 e in particolare la 8530 (come consigliato durante l\u2019installazione) ma a causa dei firewall interni alle macchine e ad altri problemi se ne sconsiglia l\u2019installazione.
\nAltra soluzione al problema \u00e8 la reinstallazione del servizio IIS e dell\u2019intero applicativo Wsus.
\nIo ho avuto quel codice d\u2019errore e l\u2019ho risolto eliminando il filtro dei contenuti (pi\u00f9 apertura delle porte 80 e 443 verso internet) presente sul firewall anziendale che bloccava la macchina che fa da \u201cserver Wsus\u201d (in quanto avevo bloccato determinati siti microsoft), in quanto non riusciva a contattare i server microsoft come indicato nella guida di installazione.
\nInfatti al passaggio 3 della guida \u00e8 necessario configurare il firewall aziendale nel seguente modo:<\/p>\n

\u201cSe \u00e8 presente un firewall aziendale tra WSUS e Internet, potrebbe essere necessario configurare il firewall per consentire a WSUS di scaricare gli aggiornamenti. Per scaricare gli aggiornamenti da Microsoft Update, il server di WSUS utilizza la porta 80 per il protocollo HTTP e la porta 443 per il protocollo HTTPS. Questa impostazione non \u00e8 configurabile.\u201d
\nSe tali porte e protocolli non sono aperti a tutti gli indirizzi, \u00e8 possibile limitare l\u2019accesso solo ai domini seguenti in modo che WSUS e Aggiornamenti automatici possano comunicare con Microsoft Update:<\/p>\n

http:\/\/windowsupdate.microsoft.com
\nhttp:\/\/*.windowsupdate.microsoft.com
\nhttps:\/\/*.windowsupdate.microsoft.com
\nhttp:\/\/*.update.microsoft.com
\nhttps:\/\/*.update.microsoft.com
\nhttp:\/\/*.windowsupdate.com
\nhttp:\/\/download.windowsupdate.com
\nhttp:\/\/download.microsoft.com
\nhttp:\/\/*.download.windowsupdate.com
\nhttp:\/\/wustat.windows.com
\nhttp:\/\/ntservicepack.microsoft.com
\nNota:<\/strong>
\nI passaggi per la configurazione del firewall descritti sopra sono validi per un firewall aziendale posizionato tra WSUS e Internet. Poich\u00e9 WSUS avvia tutto il proprio traffico di rete, non \u00e8 necessario configurare Windows Firewall nel server di WSUS.
\nAnche se per la connessione tra Microsoft Update e WSUS le porte 80 e 443 devono essere aperte, \u00e8 possibile configurare pi\u00f9 server di WSUS per la sincronizzazione con una porta personalizzata. Per ulteriori informazioni sulla sincronizzazione dei server di WSUS con una porta personalizzata, vedere il white paper \u201cDeploying Microsoft Windows Server Update Services<\/a>\u201d (informazioni in lingua inglese).<\/p>\n

Consiglio vivamente di leggere interamente la guida di installazione al seguente link<\/a> e di effettuare dei test d\u2019installazione su macchine virtuali prima di mettere il servzio in produzione. Un\u2019ottima guida, alternativa a quella microsoft, la potete leggere al seguente link<\/a>.
\nIl servizio Wsus \u00e8 utilizzabile anche in un dominio Nt4 o attraverso un server Samba, versione 3.0.14 o successiva, distribuendo via rete i cambiamenti del registro attraverso le policy, attenendosi alla seguente guida<\/a>, come descritto alla pagina 68, purtroppo solo in inglese.
\nUna guida d\u2019installazione in formato doc la potete scaricare al seguente link.<\/a><\/p>\n

**NOTIZIE IMPORTANTI**
\nIl \u201cvecchio servizio SUS sar\u00e0 dismesso dal 06 dicembre 2006 e non sar\u00e0 quindi pi\u00f9 supportato.
\nE\u2019 inoltre in produzione (ora in beta 2) Wsus versione 3 che ottimizza la visione delle informazioni disponibili con questo servizio, potete vedere una prima dimostrazione su un sito italiano con una spiegazione del funzionamento, cliccando al seguente link<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
