Lots of SMB traffic

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

Question, is it ONLY Excel spreadsheets? Or ALL MS Office files? Also is
that computer's A-V set to "scan" Office files using some sort of Office
Plugin?

Bob:

Thanks for your reply. It seems to be only Excels when they are opened via
Windows Explorer. I tried a test by doing File/Open and it opened fine.
Strange.....

You could try "Tools","Options","General", tick in "Ignore other
applications". See if that "cures" it.

Bob:

Thanks for your reply. It seems to be only Excels when they are opened via
Windows Explorer. I tried a test by doing File/Open and it opened fine.
Strange.....



Question, is it ONLY Excel spreadsheets? Or ALL MS Office files? Also is
that computer's A-V set to "scan" Office files using some sort of Office
Plugin?

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
