MS web site was the first place I looked. The temp files are deleted, normal.dot file is OK, its not a novel server and the folder is in a location they can save on. The error pops up randomly. One minute they can save to the server. The next minute someone they can't save to the network with MS office. but they can manual drag and drop the file into the network. I believe it is another program that is causing the problem. we update a program called Abra. that is about the time some user started to have problems saving Office files. Abra is a HR program that uses Fox Pro in the back end. it only happens when saving MS office files.
