Files deleted when copied over network

[Nermal]

My Mac's hooked up to a Windows machine. I can mount the Windows HD on my desktop, and copy files onto it. However, sometimes when I copy files from Mac to Windows, I see the file copy, it takes a while if it's a big file, then it just appears to delete itself off the Windows machine. Try it again and it usually works, although sometimes I need to try 5 or 6 times before the file will stay there.

This doesn't happen all the time, sometimes a file will copy perfectly, other times it takes several attempts to get the file to stay there. It seems to happen most with .exe files but I have seen it happen with other file types too. It also seems to happen most in the root directory - sometimes I end up making a folder and copying into that, which usually works.

I never have this problem when going from Windows to Mac, just Mac to Windows. My Mac's running 10.2.6 and I don't think I've installed any "special" networking software. The PC's got Windows 2000. I've got a suspicion that my anti-virus may be the culprit, it's Trend PC-cillin 2002.

Any ideas?

Heh, who knew? Files can disappear into the Ether(net). ;)

I think your suspicion is the best candidate for investigation.

Copying executables may cause your anti-virus software to see red. They could also have viruses, which may not be picked up on your Mac.

Also check your permissions, as a root directory is not a common place to copy things in a modern set-up unless you're the admin of the machine.

I'll need to do some testing with the AV turned off, it's hard to test because it's intermittent. I tried copying a pdf across today and that disappeared too. Second attempt worked.
