solutions we have evaluated are NFS clients that can be installed on Windows, in order to access data from UNIX server through NFS. The 2 solutions we have evaluated are Hummingbird NFS Maestro and Intergraph Disk Access (also available through MS Services For UNIX). We are not recommending the use of Samba based solutions : you report a data corruption issue at <COMPANY X>; I have been on my side reported data corruption issue at <COMPANY Y> with Samba based solutions. These 2 issues added to the fact that Samba solutions do not support NFS locking interoperability are enough not to recommend such solutions. What is documented corresponds to what we have successfully evaluated and what we could recommend a customer to evaluate if looking for an UNIX/NT interoperability solution (we also recommend customers to verify that these tools match their own constraints (from a security, performance, ..., points of view). If a customer reports a problem specific to one of these tool, we would be able to provide some support as we have this software available for problem determination, but in the case the problem was in the NFS client itself (and not in CATIA code), we would not be able to provide direct support on these tools are they are third party components, supported by their respective vendors. I hope this answers your question.
