Postbokser er satt i karantene og databaser mislykkes uventet i Exchange Server 2013

Opprinnelig KB-nummer: 3095369

Symptomer

I et Exchange Server 2013-miljø settes postboksene uventet i karantene, og databasen er demontert. Eller hvis serveren er medlem av en databasetilgjengelighetsgruppe, vil den mislykkes til en annen medlemsserver. I tillegg er følgende hendelser skrevet i programloggen:

Message: At '8/24/2015 8:37:03 PM' the Exchange store database 'DAG2-DB2048' copy on this server encountered an error that caused the database to be dismounted.

Årsak

Dette problemet oppstår hvis .NET Framework 4.6 er installert på serveren. I et Exchange Server 2013-miljø støttes ikke denne versjonen av .NET Framework.

Løsning

Du kan løse dette problemet ved å avinstallere oppdateringen for .NET Framework 4.6 fra serveren.

Fastslå om .NET Framework 4.6 er installert

Hvis du vil finne ut om du har .NET Framework 4.6 installert på datamaskinen, kan du se etter følgende:

• I Windows Server 2008 Service Pack 2 (SP2) eller Windows Server 2008 R2 SP1 installeres .NET Framework 4.6 som et produkt under Programmer og funksjoner i Kontrollpanel.
• Oppdatering for Microsoft Windows (KB3045562) vises under Installert Oppdateringer i Kontrollpanel i Windows Server 2012.
• I Windows Server 2012 R2 vises Oppdatering for Microsoft Windows (KB3045563) under Installert Oppdateringer i Kontrollpanel.

Du kan også bruke følgende PowerShell-skript til å finne ut om .NET Framework 4.5, 4.5.1, 4.5.2 eller 4.6 er installert:

$Reg = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey('LocalMachine', $Server)
$RegKey= $Reg.OpenSubKey("SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full")
[int]$NetVersionKey= $RegKey.GetValue("Release")

if($NetVersionKey -ge 381029)
{
    "4.6 or later"
    return
}
switch ($NetVersionKey)
{
    {($_ -ge 378389) -and ($_ -lt 378675)} {"4.5"}
    {($_ -ge 378675) -and ($_ -lt 379893)} {"4.5.1"}
    {$_ -ge 379893} {"4.5.2"}
    default {"Unable to Determine"}
}
