On a virtual desktop (Windows 7 Pro) I have several apps running (no services). The account I use is a network (admin) account. I access the account via Cisco VPN. For a long while I been accessing the account and RDP to that desktop without indecent. Ever
since I rebooted the desktop due to upgrades, the account will become disabled after about 15 minutes. This happened once before and by creating another account and running the apps on that new account worked for a while. Then the new account started "locking".
I moved back to the old account which stayed working for months until the next reboot. Trying to recreate the same procedure to keep the old account from locking again did not work.
What is causing the account to lock? How can I tell what may be causing the account to lock?
