Se su un sistema Windows 7 riscontrate nel registro eventi di sistema l’errore Application Management Group Policy 103 e i warning Application Management Group Policy 108 e 1112 e la mancata applicazione di policy in particolare di policy d’installazione di pacchetti applicativi il problema può essere legato a problemi di rete.
Source: Application Management Group Policy
Event ID: 101
Level: Warning
Description:
The assignment of application application name from policy policy name failed. The error was : %%1274
Source: Application Management Group Policy
Event ID: 103
Level: Error
Description:
The removal of the assignment of application application name from policy policy name failed. The error was : %%2
Source: Application Management Group Policy
Event ID: 108
Level: Warning
Description:
Failed to apply changes to software installation settings. The installation of software deployed through Group Policy for this user has been delayed until the next logon because the changes must be applied before the user logon. The error was : %%1274
Source: Microsoft-Windows-GroupPolicy
Event ID: 1112
Level: Warning
Description:
The Group Policy Client Side Extension Software Installation was unable to apply one or more settings because the changes must be processed before system startup or user logon. The system will wait for Group Policy processing to finish completely before the next startup or logon for this user, and this may result in slow startup and boot performance.
Per risolvere il problema è possibile utilizzare la policy Startup policy processing wait time in Computer Configuration/Policies/Administrative Templates/System/Group Policy impostando un intervallo ragionevole in base alla propria infrastruttura di rete come ad esempio 30 secondi.
Di seguito la descrizione della policy che indica come in scenari in cui il processo di sincronizzazione delle processo è sincrono il computer risulterà bloccato sino a che la rete non sarà disponibile o il tempo di delay non è trascors :
“This policy setting specifies how long Group Policy should wait for network availability notifications during startup policy processing. If the startup policy processing is synchronous the computer is blocked until the network is available or the default wait time is reached. If the startup policy processing is asynchronous the computer is not blocked and policy processing will occur in the background. In either case configuring this policy setting overrides any system-computed wait times.If you enable this policy setting Group Policy will use this administratively configured maximum wait time and override any default or system-computed wait time.If you disable or do not configure this policy setting Group Policy will use the default wait time of 30 seconds on computers running Windows Vista operating system.”
Ovviamente trattandosi di problemi di rete le cause possono essere molteplici quindi non solo legati all’infrastruttura di rete (patch, switch e configurazioni), ma anche a driver di rete non aggiornati lato client e server.
Se il problema avviene su un client specifico è possibile impostare tale policy in modo temporaneo agendo sulle policy locali del client tramite gpedit.msc.
A riguardo si veda anche la KB2421599 Windows 7 Clients intermittently fail to apply group policy at startup.
Vi ricordo anche a maggio 2016 per Windows 7 è stato rilasciato l’Aggiornamento cumulativo per comodità per Windows 7 SP1 e Windows Server 2008 R2 SP1, a riguardo si veda il post Windows 7 SP1 and Server 2008 R2 SP1 convenience roll-up now available at a download location near you! (KB3125574).
