Disabled Network Service

Access to the UW network can be disabled/unavailable for four main reasons.

  1. DMCA (Digital Millennium Copyright Act) violations
    You should have received a notice about a DMCA violation. Off-campus access is blocked and you will need to respond to the DMCA violation to get your access restored.
  2. Security Issues
    Network security scanning has detected that your computer has been compromised by a virus or other malware.
    You should have received a notice from the CISO explaining the steps needed to restore access.
  3. Network Disruption
    Network Operations has identified your network device as disrupting network service for other users, e.g. an unapproved wireless repeater, a DHCP server, a bad network adapter.
    You should have received a notice from Network Operations explaining the steps needed to restore access.
  4. Something is broken.
    It happens; older equipment fails or someone has cut through a cable. If you computer is not listed on the disabled ports list below contact Network Operations at, or by calling 221-5000 (1-5000 from a campus phone).


Getting Enabled

If you decide you may be blocked, take the following steps:

  1. Verify whether your computer is currently blocked by going to UW Disabled Ports.
    • If it indicates your port is blocked, your computer is probably infected; proceed to step 2 below.
    • If the Disabled Ports service says your port is not blocked, you have some other problem not addressed here.
  2. Completely clean your computer of virus infections and other malware. This task often involves completely erasing your hard disk and reinstalling your operating system and software. You can obtain help from several sources:
    • The Computer Vet in the Learning Commons in Odegaard Undergraduate Library can help with operating system updates, anti-virus software installation, and cleaning out infected computers.
    • Many commercial computer maintenance services are available off-campus.
  3. Unblock your connection by using your computer to go to the UW Security Tools Enable site. Important: The Unblock procedure will check to see if your computer is still infected. If it is, your computer will not be unblocked.
