Every unit at UAB with devices connected to the UAB campus network should have a "network contact" person, even if there is no department server or local area network. At least one person within your department should be designated to be responsible for communicating your requests to DC/NS, and for assisting network users with basic configuration, software installation, computer training, and problem solving.



Designate an official "network contact" person for your department.

  • Each department or unit at UAB should have an officially designated "network contact" person.


  • The dean, chairman or director designates who is to serve as "network contact" for your unit. The dean, chairman or director should send either a written memo or an e-mail message to indicating who is to be considered the official contact person.


  • Data Communications / Network Services (DC/NS) recommends that the contact person be a trained computer professional.


  • If the "network contact" person is not a UAB employee, the department should additionally designate a contact person who is a UAB employee.


  • The "network contact" person should have access to a UAB e-mail account (hostname ends in All requests to DC/NS must be submitted via e-mail (, and for security reasons these must originate from a server registered through DC/NS.


Notify DC/NS when there is a new "network contact" person, or other changes in responsibilities.

  • When there is a change in personnel or responsibilities within your department, DC/NS should be notified. The previous "network contact" may send a message to introducing the new person. If no replacement arrives before the old person departs, the last "network contact" should hand this function to their supervisor or other person in the department, who will then hand the job to the replacement person when they arrive. IP records, and any other records, should be turned in to the department for safekeeping.


  • If the "network contact" left UAB without notifying DC/NS, the dean, director or department head should contact DC/NS with the name of the replacement contact person.


Some typical duties of a department "network contact" include:

  • Manage a block of IP (internet protocol) numbers given to the department by DC/NS, and maintain records of the location for each IP number used. Requests for new IP numbers should be submitted by e-mail to new IP numbers


  • Request registration of host names in the UAB DNS (domain name service). Requests for DNS registration should be submitted via e-mail to


  • Communicate network problems to DC/NS, and assist in trouble-shooting and problem resolution. Please call 4-3540 to report network communications problems, and call 4-7777 to report network wiring problems. You may also report problems via web interface.


  • Request and properly configure other net-wide addressing, such as Novell server names and addresses, and Appletalk zone numbers and names. Net-wide addressing requests should be submitted via e-mail to


  • Coordinate equipment installation and relocation with DC/NS.

"Strange network problems" can be caused by DUPLICATE IP ADDRESSES. If the workstation can send traffic off its segment to another subnet in our 138.26 class B address range but can not get to a location off campus, it is very possible that the workstation IP address has been incorrectly set to use the campus gateway ( instead of its own address. Problems within your building network that affect only one or two machines can be caused by duplicate addresses, also.


One way to check for duplicate IP addresses is to look in the arp cache of the machine having problems. In Win 95/98 or NT, at the DOS prompt type the command "arp -a". For entry of you should see a MAC address starting like 00-00-a2....

You can report the MAC address you find to UserServices, and we will help you track down the "offending" machine.
