HI,
Firstly i suggest you read a basic book on SNMP like O'reillys "SNMP Essentials"
SNMP can work in 2 basic scenarios
1-SNMP GET
2-SNMP Traps
Before you can do an SNMP get on a PC (im assumin you have winodws installed),you must configure the pc to be SNMP enabled
1-Run the service on the pc 2-If you want to send traps then name the destination server 3-Deal with your community strings
Once you have done this ,maybe you could start with the Net::SNMP module.
