The service can be accessed from a web browser anywhere via the following URL: https://ras.ncl.ac.uk. However, before clicking on this link there are a few things you should know:
Please visit Installing the Citrix Client.
If you have upgraded from a previous version of Internet Explorer you may notice that RAS performs slowly or generates ICA error messages when attempting to load an application.
To access RAS using Internet Explorer 9 you need to have the latest Citrix Client installed, this is available from the RAS logon page. For installation instructions please visit Installing the Citrix Client.
To access RAS using Google Chrome you need to have the latest version of the Citrix Client installed; version 13.1. This can be obtained from the RAS homepage, please visit Installing the Citrix Client for further information.
Alternatively you can also use the Java Client with Chrome; visit Using the Java Client for setup instructions.
Local Printers:
In most cases, printing from RAS should be a fairly straight-forward process, the system automatically detects your local default printer. Your local printer will be identified as "Client/WI-xksieiurdkdjfk_printername [UPD]".
You can also choose to print to one of the cluster printers if you would prefer.
It is recommended that if you want to print, you choose File, and then Print as this gives you the option of selecting the correct printer.
If you have problems with printing please ensure that the printer you wish to connect to is set as the default on your local machine before connecting to RAS. You should also upgrade to the latest client, available from the RAS homepage.
If after all these steps the printer does not show up in the list of printers it may mean that your printer driver is not compatible with RAS and is unlikely to work, please try upgrading your Citrix Client to the latest version (available from the RAS login page) as each new release of the client increases printer support.
The following printers are known not to work with RAS:
Network Printers:
Use the Find Printer button in any office application (except Outlook) to connect to your networked printer using this method.
If you find that the application you are using doesn't have the Find Printer button, then logout completely from RAS and run Word and click the Find Printer button and print a test page to your printer. Logout and then this printer will be available for you for any other RAS application.
If you receive the error 'Access is denied' this means that the RAS servers do not have the available drivers for your printer. The RAS servers have the HP Universal Printing PS (5.1.1.8283) driver installed and we recommend this for most HP Printers: please contact your computing officer to ensure your local printer server is using the Universal print driver else you will not be able to print.
You can print to most business-class printers without needing to install additional drivers by using the 'Local Printers' method above.
