Cause

Det finns många möjliga orsaker till dessa fel. I det här fallet ändrades domänlösenordet efter att migreringssessionen skapades.

Resolution

Ett av följande steg kan hjälpa dig att lösa den här typen av problem:
1) Uppdatera administratörsuppgifterna i egenskaperna för migreringssessionen i Unisphere så att de matchar det aktuella lösenordet.
2) Skapa en lokal administratörsanvändare på VNX CIFS-servern med hjälp av Microsoft Computer Management (MMC). Konfigurera administratörsinloggningsuppgifterna i egenskaperna för migreringssessionen i Unisphere så att de matchar det nyskapade användarkontot.
3) Om lösenordet hade specialtecken, försök att ändra lösenordet till ett alfanumeriskt.
