Outlook 2003 is disconnected through VPN
Server: Windows Server 2003 Small Business Server
Client PC: Windows XP SP2 running Office 2003 with all M$ updates.
VPN Connection: Two Linksys RV042 VPN routers connecting to each other (Static IP to Static IP)
The client PC is connecting to the server over the VPN. Sometimes when he opens Outlook it shows the status as "Disconnected". Outlook is running in cached mode and needs to continue running in cached mode. Other users at the same site are able to access the server just fine. He can ping the server and browse to it via network places.
If I restart the Information Store on the exchange server he is able to connect again instantly.
Steps taken:
- Found an article that a M$ patch limited the TCP connections from 50 to 10. Ran another patch to allow 50 connections again.
- Added the local IP and server name to the Hosts file.
- Updated NIC drivers
- Adjusted MTU settings in the router
Thoughts?

Good stuff. I decided not to change any of my Exchange Server's settings, especially since it only affected one user and it meant I had to resolve the issue at the cause.
The reason it took one month for me to work it out was due to the fact that we had only just migrated to AD from NT4 and I thought our migration had gone slightly awry - was looking in the wrong place altogether.

It has been two solid weeks without a disconnect. Restarting the clients router seemed to do the trick. He is now receiving 0% loss when he continuously pings the server over the VPN.
za_mkh thank you for pointing out TCPview.....that program is great.
Since my company relies on email to the point of absurdity i could never restart and the only way i could fix this problem when it occationally came up was to migrate the user's mailbox to another mailstore.
No longer, your solution (using TCPview to close out the open TCP/MAPI connections) works brilliantly....I tip my hat to you.

Kristina, the server is SBS 2003 SP2 and I do see 9646 events poping up.
MKH, You may be on to something with the system losing connection.
The PC is hard wired into the network and it seemed like I was able to ping the server just fine. However, when I pinged the server 100 times I had anywhere between 4-11% loss.
I am going to reboot the router after hours tonight to see if things improve.
