Now You Know – NACS Web site resources

The NACS Web site ( allows faculty and staff to gain easy access to information about computing and networking services. This article surveys some of its features, but there are many more you can discover on your own.

Downtimes and problems report

The top item in the left-hand navigation is a “Systems Status” alert box. In it you can find which NACS services and resources have known problems, and any information we have about when to expect resolution.

Blocked list

The number one quick link in the right hand navigation bar is the “Blocked Systems List.” When a computer at UCI is being denied access to UCInet (and the Internet) because it represents a threat to the other systems on campus, it will be found in this list. If you are ever affected by this, NACS is ready to work with you to correct the problem.


A little further down on the list of top quick links is NACS’s “Knowledgebase – FAQ”, a collection of frequently-asked questions and answers, updated as issues of interest change.

Campus software licenses

The campus has arranged for discount licensing of a wide variety of academic and productivity software. The campus “Software Licensing Database” is easily accessed from the list of top quick links.

My E-mail Options

The left hand navigation bar includes a list of “service tools,” quick access to key on-line resources. Among those tools is “My Email Options” which allows users of NACS Mailbox services to check their disk quota or configure their email service (setting up a vacation message or tuning the selectiveness of the spam filter).This is but a sample of the information and tools readily available through the NACS Web site . If you have suggestions for other NACS online resources you would like convenient access to, please contact NACS.

Blocking Misbehaving Systems Protects UCInet

NACS is working hard to ensure that a robust and secure UCInet is always available to do the University’s business. To that end, we will occasionally deny access to systems which threaten the safe operation of the network.

Whenever a system connected to the UCInet is discovered attacking other computers, or engaging in other forms of inappropriate behavior (such as the illegal distribution of copyrighted material), NACS may block that system from further network access. Occasionally, NACS may also block systems that have not been patched in a timely manner against particularly nasty viruses.

There are two simple strategies you can follow if you suspect your system has been blocked. You can search the blocked systems list at (usually, you’ll need to use an unblocked system to do that). Or, you can call NACS at (949) 824-2222. Our helpful consultants will explain why your system was blocked, and what to do to correct the problem. Generally, once you have taken the appropriate steps, the system can be unblocked within a few hours. Please note, however, that unblocking can only be performed during regular business hours except in emergency situations.

NACS is responsible for UCInet, but you are responsible for the proper operation of your own systems. By staying up to date on security patches, and by carefully abiding by the Computer and Network Use Policy at you can preserve your access to the UCInet and help guarantee a secure and reliable service for the entire campus.
