You may receive the "Internet synchronizer exited unexpectedly on the server" error message when you try to initiate Internet synchronization of a Microsoft Access-replicated database
This article applies only to a
Microsoft Access database (.mdb).
Advanced: Requires expert coding,
interoperability, and multiuser skills.
After you initiate Internet synchronization to exchange the
data in a Microsoft Access-replicated database over an Internet connection, you
may notice that the Internet synchronization is not completed successfully.
Additionally, you may receive the following error message:
Internet synchronizer exited unexpectedly on the server. Look at
the partner replica exchange history on the internet server to figure out the
problem.
Capitalization and wording for this error message has been
verified to match the error message that appears on the UI.
This
problem occurs when all the following conditions are true:
- The Internet server, also known as the Web server, that is
running the Internet synchronizer is on a private local area network (LAN) that
is connected to the Internet.
Note The Internet synchronizer is named Mstrai40.exe. - The LAN uses a router that has Network Address Translation
(NAT) that is enabled to communicate with the computers on the
Internet.
The Internet synchronizer tries to communicate with the Web
server by using the unique external Internet Protocol (IP) address or the
domain name of the Web server. Because the Web server is in the same local area
network and is configured to use the same NAT router, the NAT router cannot map
the external IP address or the domain name of the Web server to the internal IP
address of the Web server. Therefore, the Internet synchronizer cannot connect
to the Web server to do Internet synchronization successfully.
If Internet replication is setup by using the domain name of
the Web server, you can resolve this problem by editing the Hosts file on the
Web server. You want to map the domain name of the Web server to the internal
IP address of the Web server. To do this, follow these steps.
Note You cannot use this method if Internet replication is setup by
using the external IP address of the Web server.
- Start Microsoft Windows Explorer.
- Locate the Hosts file.
By default, the Hosts file
is at the following
location:
<WinDir>\system32\drivers\etc
Note The <WinDir>
placeholder is a placeholder for the path of your Microsoft Windows folder
where the operating system files run from. - Open the Hosts file by using Notepad.
- Add the following line at the end of the Hosts file to map
the domain name of the Web server to the internal IP address of the Web
server.
<IP Address> <tab
character> <Domain name>
Note The <IP Address> placeholder is
a placeholder for the internal IP address of the Web server. The
<Domain name> placeholder is a placeholder for
the domain name of the Web server.
For example, if the domain name of
your Web server is "ReplicationDomain.com," and the internal IP address of the
Web server is "192.168.150.144," you must append the following line to the
Hosts file on the Web server:
192.168.150.144
ReplicationDomain.com - Save the Hosts file.
Notice that you can
successfully synchronize the data over the Internet.
To work around this problem, use one of the following
methods:
- Use a virtual private network (VPN) so that the remote
computers that participate in your Access replication can connect to your Web
server for Internet synchronization.
For additional information about
VPN, visit the following Microsoft Web site:
Virtual private networks
for Windows Server 2003 - Connect the Web server to the Internet directly by removing
the NAT router.
When the users of your Access database replication try
to connect to the Web server over the Internet connection, the external IP
address or the domain name of the Web Server is correctly translated to the
internal IP address of the Web server by the NAT router.
