extra trailing . on path for tree connect

I'm getting some unexpected packet contents from a windows XP client on 
restarting an interrupted samba 4 session.

If I have an open windows explorer view on windows XP and then restart 
Samba and then refresh the open window by executing from a command window:

start \\es3300-c5559f6a\test

Then I get the unexpected packet below showing that an extra trailing 
dot . is added to the path-name at offset 0x0094 so that the connect 
attempt is to:

\\es3300-c5559f6a\test.

instead of

\\es3300-c5559f6a\test

Does anyone recognize such behaviour, or know the cause of the . or what 
it might signify?
