Why Does This Error Happen?
This error can occur due to:
- Bandwidth Throttling: The Exchange Server administrator may have limited bandwidth on Exchange Server 2000 or 2003.
- Internet Issues: No internet connection or a firewall blocking the connection.
- Background Programs: Other apps using up bandwidth.
By addressing these issues, you can eliminate this frustrating error and get back to work.
What could be the reason behind this error message?
This error message appears when the Exchange Server administrator enables bandwidth throttling on Exchange Server 2003 or 2000.
Other causes of this server error message include no internet connection, a Firewall on the Wi-Fi connection blocking access, or background programs using up bandwidth.
So how to fix the error: ‘Your server has unexpectedly terminated the connection’?
If you are the administrator of the Exchange server, then you can follow the steps below to disable bandwidth throttling on the Exchange server:
- Go to Start, then Programs, and Administrative Tools, now click on Internet Services (IIS) Manager
- Right-click the websites, and select Properties
- Next, click on the Performance tab, and clear the Limit total network bandwidth available for all Web sites on this server option
