Connection is cancelled when the Windows Firewall settings are changed after a TCP/IP connection is established between iSM clients and a server.
Situation
While using an NEC Storage Manager (iSM) client on a PC running Windows XP SP2 (Service Pack 2), if the Windows Firewall settings are changed after a TCP/IP connection is established between iSM clients and a server, the iSM clients/server detects channel abnormalities and ends the connection.
Conditions
This occurs when all of the following conditions are met:
- An iSM client is used on a PC running Windows XP SP2.
- Windows Firewall was set as follows before an iSM client/server connection is established ([Control Panel]-[Windows Firewall]-[General]):
- Windows Firewall is "ON."
- "Don't allow exceptions" is unchecked.
- The Windows Firewall settings are changed as follows after an iSM client/server connection is established:
- "Don't allow exceptions" is checked.
How to handle
Do not change the Windows Firewall settings after an iSM client/server connection is established. If the problem occurs, re-establish the connection. The iSM client/server does not have to be restarted, but wait for a few minutes if connection must be re-established.
