  2. Go to User Management console (Local Users and Groups)> selectPLUS_AGENT> right click on properties > Uncheck Account is disabled and Account is locked out > click apply.
  3. Wait a few minutes for agents to log back in again.
  4. Go to C:\WINDOWS\system32\LogFiles\W3SVC67 and look for the newest file created.
  5. In this file you will want to search from the bottom up. Find 200 on the list. This is the last successful login. The next login will have a 401 code, this is the agent that is locking up the PLUS_AGENT user and preventing the other agents from logging in.
  6. Disable that agent from running and repeat steps 2-5 until all of the agents have logged in. This will ensure that no other agent are corrupted.
  7. Uninstall and reinstall the agent on the machine causing problems then test again.

Additional Information

This problem is usually caused by having a space before or after the serial number when the agent is installed.
