ABC location main server Symantec is not updated. For this reason, ABC computers are not updated. Once the server is updated, (we/the company) will automatically update all client computers. another option is to use has/have been... ABC location main server Symantec has not been updated. For this reason, ABC computers have not been updated. Once the server has been updated, all client computers will be updated automatically. Either work. You can play with the wording. Good luck!
