We run a lab of ~120 NT workstations. We have a problem with samba when Command Softwares AntiVirus is enabled for dynamic virus scanning of network drives. Office files get corrupted and/or can be saved. The client machines are all NT 4.0 sp4 with Office 97 sp2 The servers are solaris boxes running Samba 2.0.3 The problem can be seen by repeatedly modifying and saving a document stored on a samba share. On the thirdish attempt an error dialog comes up stating that the file can not be saved. (In use, access denied etc). Locking is turned on. So is strict locking. OLE compatible locking is on. What else should we look at? With Network virus checking turned of the problem is not visible although we do seem to be getting a number of complaints about corrupt documents. With Network virus checking turned on the same operations to an NT 4.0sp4 server share work fine. Any suggestions would be welcome . michael@ecel.uwa.edu.au ECEL, The University of Western Australia
