In the context of you trying to reach a server on TCP port 445, based on the relative sequence number it looks like the application is running and some data has been exchanged, but very early on the server is abruptly killing the TCP session, likely due to application-level error.
Note, I'm assuming that packet came from the server based on the source mac being Cisco and the destination being more likely to be a PC. That and the source port is in the well-known range, so likely the service port reached by the client.
Also note, a 'reset' is a warning because it MIGHT be a problem. Some applications are just written such that they kill TCP sessions this way in normal conditions.
