Getting locked out of EWS workstations

Reasons why you may be locked out of your computer

There are a few reasons why you may be locked out of your computer, depending on the original problem:

Password expiration and/or locked account

Your AD password requires changing once a year. If it needs changed, you will not be able to log into any EWS machine. Visit to change or update your password. 

Quota issues

EWS users are given 10 gigabytes of storage that is shared between EWS Windows and Linux. If you fill up your disk space (or "quota"), you won't be able to write additional files to your drive and the system may respond oddly. Below is a list of different symptoms that you may see.

  • On a Linux machine, your computer may be complaining about problems locking the .ICEauthority file.
  • After logging in, programs might complain about not being able to write their files to your drive.
  • Windows computers may not allow you to modify or remove existing files.
  • The computer won't let you log in.

Checking your quota from Linux

Log into an EWS Linux workstation and open Terminal.

Type quota <your_netid>. Press Enter.

The following is an example of what an over quota account looks like. The first number is the space used. The * next to it indicates you are indeed over your quota. This can be verified by comparing that the number under the blocks column is bigger than the number under the quota column.

An over quota account looks like this.

The following is now an example of a user that is under the quota limit. Notice the absence of the *.

Resolving an over quota issue

If the EWS machine lets you log on, you can potentially resolve the issue yourself. The easiest quick fix is emptying your Recycle and Trash bins (on Windows and Linux, respectively).

To find large files in your drive, run the following command in the terminal:

find ~ -size +100M -ls

This will give you a list of files that is over 100MB. You can remove them with the rm function. Try deleting old files from classes you are no longer in, or things you do not need.

If you are having trouble getting this to work and you are still over quota, please contact for assistance.
