we have a few of these sensors and they operate very well.
Very occasionally the SNMP communication fails i have found this to be due to the public password being changed (all by itself). I think this is as a result of some other program messig with the passwords.
Environment is all microsoft servers??

has anybody else experienced this problem (it has only occured twice in over a year so it is not critical in any way but it would be nice to sort it out)
