  Hi All

  I am trying to get some sort of explaination regarding what I am seeing with a whole bunch of tcp ports opened from a single tcp port source from another server. The port is 445 and yes - I know this is used for a number of things but one of them is log shipping.

  I have a log ship primary ServerA and the destination folder on ServerB.

  Both servers Windows 2008R2 Server - SQL is SQL2012. Logshipping from ServerA to ServerB

  On ServerB I can seea lot of ports opened (hundresds) when I run wireshark I can see that they are accessing *.trn files on a folder designated for the transaction log files. In computer manager - shared folders tab I can see that the logship folder is open (again hundreds)

  I can understand that log shipping will make use of this as port 445 is used by SMB, AD authentication and some others - but what I don't have an explaination is why it is that they are still open. When I shutdown the server service the ports close.

  I cannot see that this same issue on another server with logshipping - I cannot find anything on the net regarding this - why the ports stay open - anyone out there encountered this before

  thanks
