Invalid Arguments error when trying to open import manager

Hi,

I facing a new error when trying to open import manager. When i open it after giving username and password for selected repository, i am getting the error as "Invalid Arguments". It is occurring for all the repositories in that server. When i checked in logs i'm getting the error as "[MDS=60@m7pci Repository=Ford_BP_ZA]: CatMgrClientWorker.Connect() failed. RC: 0xffab4005 Incorrect arguments " . Can some one please suggest on what can be done to resolve this issue.

Thanks
