Check In job fail

Hi

    I install View Client 5.4.1 with Local mode client on Win7 Enterprise Sp1 X64, I check out a WinXP VM to local.

when I verify local VM function , then perform "Check in". it start analysis Disk and try upload data to Server, the job fail as attachment.

I check event log from Server , it has no error message but a info message "Failed to clean up disk null on Transfer Server XXXXXXXX"

I search google...only seem check out fail and "internal error" page..no similar me...

Who has such experience could provide some information to me ?

thanks!!
