How can I investigate this (is there something like "lsof" in Windows)?

If you're speaking about "process", do you mean the "sshd" process? And 
what could be a reason for it to access any remote file system? My home 
directory is on the hard drive, I surely use some remote file systems 
sometimes (by opening file explorer and copying files), but I don't see 
any reason for sshd to do the same.

Is there any explicit way to "unmount everything remote" in windows? I 
close all the explorer windows, but of course it could be not enough.

What kind of "DNS problems" could it be? I disabled reverse DNS query 
(if I correctly understand meaning of the option "UseDNS") and see "last 
login from xxx.xxx.xxx.xxx" message now (where xxx are digits).

Oh, thanks! I was getting over-suspicious :)
