Hello:
I am new to packet sniffing. I had a user complain that it was taking to
long for an Excel spreadsheet to open. I tested from my machine and it only
took about 5 seconds which is what I would expect it to take. From his
machine it was taking over a minute! I installed WireShark on his computer
can did a sniff while attempting to open the file. In the sniff I saw a
tremendous amount of SMB traffic. I have been googling this to try and make
sense but still am not sure what is going on. Below is a what I am seeing.
Any advice would be appreciated
