Klávesy sa nedajú obnoviť, Helpdesk portálu alebo Self Service Portal. Nových klientov chyby pri pokuse o šifrovanie ako služby MBAM stane nedostupnou. To spôsobí časových limitov a iné chyby.
Okrem toho nasledujúce chyby v denníkoch sledovania svc MBAM c:\inetpub\Microsoft BitLocker správa Solution\Logs\Recovery a hardvéru Service\ * .svclogs:
Transakcia (proces ID 63) bol zablokovaný zámok zdrojov s iným procesom a vybral ako obeťou zablokovania. Znova transakcie. Uncommittable transakcií v priestoroch na konci dávky. Vrátení transakcie.
Riešenie
Na vyriešenie problému Aktualizujte uložené postupov MBAM obnovenie databázy. Vykonáte to spustiť nasledujúci Transact-SQL skripty:
