Ok at work I was given the task of fixing a rather odd problem. And I'm about out of hair. After me the task gets outsourced.
The problem.
One computer on a network segment of about 12 computer is losing connection to Exchange server. It only loses connection when opening something in outlook or clicking on something in outlook, If you leave the system sit is does not reportedly lose connection. When it losses connection to the Exchange server it also losses connection to the file server (same server as Exchange server) when outlook losses connection to the server is goes into a not responding state and some times when it losses connection to the Exchange server the open outlook window will crash (close out on its own). Emails are also coming in delayed, anywhere from a few minutes to a day, But its random, I can send the user a email and its delayed but another users email will go right through. (Both being from the same domain)
The system is a HP allinone (don't know the model off the top of my head) running windows7_32bit running office 2007. The system is fully upto date. The server is running server 2008r2 and Exchange 2010. The computer is connected to the sever via a 24 port switch in the main office running to a fiber switch to the building next door then into a dlnk switch with 12 other computers on the last switch.
No other users are having this problem and about 20 users are using the Exchange server at any given point.
What I tried so far.
SFC.
Outlook ost/pts scan/fix
Reinstalling outlook.
Removing the outlook profile from the system.
Trying both cached and non cached mode.
Testing the cat5 drop and cat5 cable going to the computer. (tested good)
Putting the computer on wifi without disabling Ethernet
Changing the network ID name on the computer.
ipconfig /flushDNS
ccleaner with winapp2.ini.
AV scan with both malwarebuyts and vipre.
Making sure MTU setting are all right.
Had the user login to another computer and use it for a wile (it was fine)
Safe mode (did not fix the problem)
Reset send receive options.
What I have not tried.
Reinstalling windows.
Removing the hole user profile form the system and reading it.
Removing the system from the domain.
Replacing the computer.
Wireshark (packet loss test)
Attached is the event logs when outlook losses connection to a Exchange server.
I just disabled the Ethernet connection and left it on wifi only just incase the user is on a bad port on the switch.
I'm about out of ideas and most of the ideas I have left I don't really want to do. And advice would be helpful.
Thanks in advance.
