Narrative:

Approaching the bewee intersection on the CONLE1 RNAV departure; potomac departure asked if we had been assigned a vector. We stated that we had not and that we were approaching the bewee intersection of the departure procedure. They informed us that we appeared to be 5 or 6 miles off course. Both the first officer and myself were puzzled since the proper runway and procedure were entered into the FMS. Additionally; both of our flight instruments were indicating that we were on course with the autopilot engaged. Upon further review when workload permitted; we reviewed our flight plan and did not notice any discrepancies. All standard operating procedures were complied with for an RNAV departure procedure to include briefings and autopilot engagement.
