Hello,
Thank you for your question and reaching out. I can understand you are having issues related to Password.
Please ensure that if there is no no group policies set that enforce password changes on every reboot.
Also Check the each affected machine, run secpol.msc to access the Local Security Policy. Check for any policies related to password changes on reboot.
Verify if there have been any changes in password expiration settings recently.
Also have a look on Event Viewer logs that might provide more information
and check if there is any malware on the main server.?
Determine if there have been any recent updates or software installations that might be causing this behavior. .?
and see it helps.
Thank you
