Windows firewall considerations

If the Communication Driver runs on a computer with a firewall enabled, there is a list of application names or port numbers that must be put in the firewall exception list so the Communication Driver OI Server can function correctly.

By default, the Communication Driver installation program makes the required entries in the firewall exception list. If you do not want the installation program to make entries in the firewall exception list, you must add the entries manually. For information on how make entries in the firewall exception list, see your firewall or Windows security documentation.

Whether you let the install process add the entries, or add them manually, the following applications must be put in the firewall exception list on the computer running the Communication Driver:

• GESRTP.exe

• aaLogger.exe

• DASAgent.exe

• dllhost.exe

• mmc.exe

• OPCEnum.exe

Whether you let the install process add the entries, or add them manually, the following port numbers must be put in the firewall exception list on the computer running the Communication Driver:

• 5413 a TCP port for slssvc.exe

• 445 a TCP port for file and printer sharing

• 135 a TCP port for DCOM

The following applications must be in the firewall exception list on the computer where the OI Server Manager is installed:

• aaLogger.exe

• dllhost.exe

• mmc.exe

The following port numbers must be in the firewall exception list on the computer where the OI Server Manager is installed:

• 445 a TCP port for file and printer sharing

• 135 a TCP port for DCOM

Un-installing the Communication Driver does not remove the firewall exception list entries. You must delete the firewall exception list entries manually. For more information on how to do this, see your firewall or Windows security documentation.
