Look on the software or hardware supplier's support web site
Try a general web search using a search engine. Typing the exact wording of an error message into Google (within double quotes) often finds a page outlining the problem and its solution
If you have problems with your IT accounts (such as a forgotten password), you may be able to solve these through the Webauth or Self-Registration websites.
Step 2: College and departmental IT support
If you can’t resolve the problem yourself, consult your college or departmental IT Support Staff. They will be familiar with local IT systems and will also know about any problems affecting the college or department network or servers.
Step 3: Contact the IT Service Desk
The central IT Service Desk provides technical support and advice to all members of the University on a whole range of IT problems.
To contact the Service Desk, phone them on 12345 (please have your University Card to hand). Telephone support is available 24/7.
