Agent or Server unreachable on Windows XP™ SP2

Symptoms

An Impulsus isymon agent or the Impulsus isymon server seems to be offline, but is not. The synchronization dialog may display “Offline” status for the isymon agent.

Cause

This has to do with the Microsoft Windows XP™ firewall configuration. The isymon RPC ports may be locked.

Resolution

You can check this by temporarily disabling the firewall functionality. Please contact your system administrator before doing this. The standard ports are 8095 and 8096.
