i've tried to turn on the branch and workarea security. It 's still the same error. For your second suggestion, i'm not able to view the security setting of the workarea via Windows Explorer simple because permission denied. I don't understand why. I login to the server using a userid who is a member of Administrators group. Aren't it's the same as administrator user? why i can't view the security setting?
