I will try to show it on an example.
Let's say I want to copy 2 files (file.txt and file.exe) from WinNT 4.0 Wrks station to Win98 (copying form Win98 to Win98 works ok).
1. I copy it to not mapped share (I mean first I call in one of TC panel command cd \\comp98\share1). Everything is Ok, all the source dates of files are preserved.
2. I copy it to the mapped share (I mapped the share as a drive X: ). It's not Ok now - the date of file.txt is preserved and file.exe - has new, current date. Surprise!

3. If I use for copying Windows Explorator - it works correctly.
Any ideas why it works this way?
BTW: If I copy with TC to Samba shares mapped as drives it also works correctly.
