a single wmi sensor works, adding "wmi vital system data v2" fails (80070005: Access is denied)

Dear jwf

Are you running the WMI Tester locally on the computer which you like to monitor, or on the probe? Which Windows version runs on the computer which you like to monitor?

probe (prtg server) is windows 7 64bit 192.168.62.97,

there is NAT between the probe and destination. 192.168.1.0/24 subnet is transformed into 172.16.222.x.

destination is windows server 2012r2 64bit, 192.168.1.15 (probe sees this machine as 172.16.222.15)

i run the wmi tester on the probe and query the destination.

all ports/protocols are allowed between the probe and destination. identical username and password exist on both the probe and destination.

Dear Jwf

Is the monitored computer part of a different domain / workgroup? Please try localhost as domain.

Please also check the credentials which you put into the PRTG device settings.

yup, setting domain as localhost allowed wmi-vital-system-data-v2 sensor to complete.

i went back and removed the localhost to confirm, and yes it is necessary.

summary: not specifying domain works when adding a single wmi sensor, or using the wmi tester utility. specifying 'localhost' as the domain is necessary to get a multiple wmi sensor to configure.
