All questions related to installations, configurations and maintenance of Advanced Host Monitor (including additional tools such as RMA for Windows, RMA Manager, Web Servie, RCC).
Normally you don't have to restart service. Do you see any errors in the log file (log2.txt by default) and/or NT Event Log? Errors like "Cannot open port ... Probably port in use"?
If yes, I would recommend to change TCP port used by RMA, e.g. set port 2055
RMA Rocks, by the way!! Thanks for an awesome product, Alex!
