Does anyone happen to use PowerGrade accross a firewall? We use PowerSchool and PowerGrade in our district grade school, middle school, and high school. PowerSchool currently works for everyone. Teachers at the middle school and high school can connect PowerGrade to the PowerSchool server (located at the high school, with an external IP address), but the grade school folks cannot. The grade school is running sme 6.01, the other schools are not running a firewall. We are getting "An error occurred when attempting to contact the PowerSchool server: Authentication attempt failed -2014" I'm guessing that this is probably a firewall thing. There is an SME Linux router at the grade school, and maybe a port is being blocked or something? I'm not a firewall wiz, so any help or pointers in the right direction would be appreciated.
