Rejoin them. Reset account does not work in your scenario. If you do not like to go to the PC locally and join them, establish remote desktop to them and Rejoin them. :P

The reason is they lose their trust relationship with domain. Incorrect DNS setting, wrong time settings and etc. If they can not connect to domain, they will not be able to synchronize their computer password with domain so the secure channel breaks. I have a detailed blog about secure channels:

By rejoining the computer to the domain, the issue should be fixed.

However, it might have happened because of one of these reasons:

1. Someone joined a new computer with the same name of an existing one. In this case, the existing computer will no longer work
2. Your AD replication is not working fine. You use repadmin to check it and also use dcdiag to check your DCs health state. You can refer to recommendations I shared here: http://www.ahmedmalek.com/web/fr/articles.asp?artid=23
3. Your security software is the one causing that. You can try to temporary disable it for testing

No rejoin locally and remotely, then forget it. :)

However this might help:
