Deep Dive troubleshooting question

We struggled with something similar recently... In our case, we had a single WMI account across all hosts in a group and we knew it was correct, but we would see accounts logouts happening almost constantly.

We thought the same as you - that there is a credential cached somewhere, or a credential set wrong on a host or a credential hard coded somewhere.  We didn't come across a way of troubleshooting it, one of my colleagues did find the root cause though.

In our case, the issue was due to currency chars in the password - specifically the $ sign.   This was causing some of our PowerShell based property/data sources to do handle parts of the password as if we wanted it to do string interpolation.  Of course, the variable it was replacing portions of our password with didn't exist, so it had the effect of removing a portion of the password at runtime.  We were using double quotes rather than single quotes in a PowerShell script.
