This problem came up years ago and I added some hacks for Columbia. I am pretty sure I notified columbia about the problems. My speculation is that they do not have the resources to fix the server. In any case, I apparently made the mistake of removing those hacks because I thought that the Columbia server had been fixed. I will go dig them up from the previous version and re-install them (if I can). =Dennis Heimbigner Unidata Ticket Details =================== Ticket ID: XXI-796914 Department: Support netCDF Priority: Normal Status: Closed
