Outlook Disconnecting/Reconnecting issue
Posted on 2011-10-27
Server 2008 Standard Service Pack 2 64-Bit
Intel Xeon x5650 2.67GHz
12Gbs of Ram
Exchange Server 2007 Version 08.03.0213.000
Windows 7 Pro PCs
We have a customer where the user’s outlook is going to a disconnected state. And then within a minute or so it will reconnect. It happens randomly throughout the day, some users experience it more than others.
The issue seems to be most prevalent in Windows 7 Pro PCs. Running Office 2010. There is one user with Windows 7 Running Office 2003 that is seeing the issues as well, while the other 3 in her office are working just fine.
When it goes to a disconnected state, internet and other network traffic works fine. I have run ping tests to the exchange server from PCs with the issue and it doesn’t lose any packets.
The network layout for this building is separated into multiple offices that all go back to one SonicWall Firewall. All PCs/Servers/Devices on this network are statically set for IPs.
All the offices have their own domain server or are just on a workgroup. The one dept with the most issues is actually on the same domain as the exchange server. The single office 2003 user is on a different domain.
In the office with the most issues has about 35 PCs/Laptops and only about 6 or 7 with Windows 7 Pro are seeing the disconnect/reconnect issue.
They are using Panda Antivirus Software.
Each Dept. has their own Switche(s). The switches are linked back to each other by fiber connects. Then back to the server room where the exchange server is located.
I will add more notes as I get them.
