The total number of ATQ threads in use has exceeded one or more thresholds

Question

Hi,
I need some help to understand this issue:
scom alert about an error on one domain controller:
The total number of ATQ threads in use has exceeded one or more thresholds
Failure to retrieve the raw performance data for NTDS via WMI:
The error returned was: 'Object required' (0x1A8)

Someone can help me to understand how can I analise this alert?
Big thanks for any suggestions.
Faye

Answer 4

Not sure what is meant by "unlock" but you could try rebuilding the performance counters or disable them if you don't use them.

Answer 5

Thanks for your suggestions.
I rebuilded the performance counters but the error is still present. I don't think that disable this counter is the best solution.
We have 9 windows server 2016 domain controller, different sites, and I get this error only on one.
