Loss of connection to the exchange server


I have an Exchange server 2003 running on a windows 2003 server.

One user is running an xp laptop and keeps getting the disconnected from exchange server message. The only way I've been able to get her client back connected is to restart the information store on the exchange server. The weird thing is, her iPhone still syncs even though her client keeps getting disconnected.

The cause of this seems to be if her laptop looses wireless connectivity to the network. If worse comes to worse, I'll move the WAP closer to her and see if her network is more stable and doesn't drop out. But I cant help thinking its an exchange connection issue and as such I'd like to get it resolved rather than have a work around.

It seems to me that the exchange server isn't releasing her connection when its getting disconnected. I've had a look about and read on another forum that there is a 10 min limit where the connection will close if not active, but this problem has lasted for over an hour.

Any thoughts/suggestions on how I can resolve this?

What I talked was about MAPI connection.. As the wireless disconnection happens, Outlook is not closing the connections with Exchange. And the next time when client get connected, the ip address may be a different one.

Mobile will get synced as its using Activesync which is using HTTP behind.

On ESM, Locate the Database of this user and go to the "Logons" folder.
You need to click on View > add remove columns > Client Ip address and click OK
See how many stale entries exists.

We have one more way to remove the stale connections but I dont remember it right now. Will recollect and post it later.

Yes, You are on the right track. Exchange will allow only 32 connection through Outlook.

The best thing I suggest is to remove this users stale connection from Exchange System Manager.

Good luck

Thanks alot for this, I can see that the user has alot of active connections, but they all seem to be from today, no stale ones. when they get disconnected, is there a way of killing the connections?

We used cport in similar issues.


Run cport from the exchange server. This exe will show all connections made  based on the services running.

The next time you face the issue, check for the session and identify the stale one.
Kill that connection using cport.

Hope this helps.

Good luck.
