This is a consistant problem that has come back after beeing corrected several times. In some cases I have to remove the computer from the network to a work group and then add it back and then the reports work. In other cases, completely removing the citrix client and reainstalling has corrected the issue. it works for a few days and then the errors are back.
this is only happening to one user.
