I am experiencing issues with XP clients writing files to a oes 9 server.

I am aware of the problem on zip files and files solidworks cad files.
Compression is not enabled on the volume.

Users are reporting files that they are unable to open and that the
checksums are incorrect.

Let me know if there is an obvious next step or particular version
numbers (ncp, nss) etc that may be relevant.

Thanks in advance,

Regards, Andrew
