DX (Digital Radiography) modality

Does anyone else have problems with some DX modality studies? I have problems on occasion getting them to send to a Conquest Dicom Server storage. The server just says "*** connection terminated" and the sending of the study to the Conquest server fails. Using conquest 1.4.16.

Maybe from a portable device. The CR images that we do here in the clinic are about 10 MB each in size. The dicom image on a particular DX study brought in on disk is only about 7.5 MB . Is there anything in the header that would help you identify a problem? A specific line item? I almost feel that it is just my lack of knowledge about the images and a configuration problem.
