Have noticed a problem with at least Client 2 SP4 IR7a when read & write
file caching is enabled on Win 7. Files copied to an OES share from
windows explorer or anything else for that matter end up with their
modified date being the time stamp of the copy rather than that of the
original file. Disabling write caching fixes it. This one may well
exist on other versions of Windows or possibly other versions of the
client as well, haven't had time to test on others. Ran with this one
creating problems for some time before finally noticing what was really
going on. Just a heads up for anyone who cares about modified time
stamps not being corrupted.
