Please help : Strange 'file has vanished' behaviour with rsync on windows.

[Jim Salter]

What are "mypc1" and "mypc2"?  Can you successfully ssh into them?  Can 
you successfully ssh into them as user1 and user2?  When you do ssh into 
them as user1 and/or user2, can you cd into /myshare1/dir1 and 
/myshare2/dir2 ?

You need to be very specific about what you're actually doing and what 
you have set up, or we can't help you.
