I had setup workflow for Purchase Order Approval via Workflow Maintenance window. But, upon clicking Submit on the Purchase Order Entry window, I en-counted an error "[Microsoft][SQL Server Native Client 10.0][SQL Server]A.NET Framework error occurred during execution of user-defined routine or aggregate "GetAssignedUsers". System.IO.FileLoadException: Could not load file or assembly 'System.DirectoryServices, Vers[
Anyone can advise what can i check to resolve the above error?
