IF you would like I will help interpret the wireshark logs for you.
What i need is a log from wireshark running on one of the client machines.. I need
it to log while the computer is working properly all the way until it stops working.
I need to know what it is that you are attempting to access that is no longer accessible
and the most exact time you can get as to when the problem started occuring.
Wireshark logs can get real big, so try to capture as little data as possible.
You can send me a private message and we can communicate through e-mail, or you can
post the log at a file sharing site for me to download.
