Cause

Der er mange mulige årsager til disse fejl. I dette tilfælde blev domæneadgangskoden ændret efter oprettelse af overførselssessionen.

Resolution

Et af følgende trin kan hjælpe med at løse denne type problemer:
1) Opdater administratorlegitimationsoplysningerne i egenskaberne for overførselssessionen i Unisphere, så de stemmer overens med den aktuelle adgangskode.
2) Opret en lokal administratorbruger på VNX CIFS-serveren ved hjælp af Microsoft Computer Management (MMC). Konfigurer administratorlegitimationsoplysningerne i egenskaberne for overførselssessionen i Unisphere, så de stemmer overens med denne nyoprettede brugerkonto.
3) Hvis adgangskoden havde specialtegn, kan du prøve at ændre adgangskoden til en alfanumerisk.
