There's a fuser in the psmisc package, but the latest version doesn't
work as expected, downgrading to the previous psmisc package helps
for now.  But I don't think this will help you here.

Any process on the server started during login.

Most likely it's something in your login scripts.  For instance,
consider expressions like this:

  my_path=/foo
  ls /$my_path

This results in a `ls //foo' call.  // is the top-level of all UNC
network paths.  THis call will result in Cygwin searching for a machine
called foo.

I'm not an expert, but any kind of DNS communication problem can result
in delays trying to resolve a machine name.  I don't know, it's just
some arbitrary idea for the potential cause of a spurious delay.
