SNMP error # -2003 after going over this entire knowledge base




Trying to get snmp sensor on a file server. Server is windows 2008 with snmp service activated and running. configured the community, firewall is off, both prtg server and file server on the same network without a firewall in between and all I get is error 2003.

tried the snmp tester - the same. no response at all.

tried restarting, opening ports, disabling fw on both computers, and still nothing. Went over 20 pages in this wonderful forum and tried all the possible solutions offered and still nothing.

ran wireshark on both computers, i can see a 'get' packet on the file server, but it just doesnt reply.

Does anyone have any idea if i am missing any settings on the prtg monitor or the windows server 2008?

any assistance will be greatly appreciated.

in the Servers SNMP Service security settings you do allow SNMP requests from the PRTG PC2

Did you already try the Tester directly on the server and request data from the server? (Local and Device IP is the same)

although the server was marked to accept SNMP request from 'any' host, I put the server address manually and it now works.
