When I was Monitoring a Network With prtg? I saw All of the sensor in prtg For 5 Minutes Down and Then All of them Up then I saw Error was No Response[Check Fire wall add ....] [snmp Error 2003].

I checked the server and I saw Its ok . Now I cant Understand. Whats the Problem? Thanks

Dear Akbar,

The error message 2003 indicates that the SNMP packets timed out. This might be caused by a firewall or something similar inbetween the PRTG probe and the target device. You can follow this link to troubleshoot the connection.

Best regards, Felix
