A globally unique identifier or GUID is a special type of identifier used in software applications to provide a unique reference number. The value is represented as a 32-character hexadecimal string, such as
{21EC2020-3AEA-1069-A2DD-08002B30309D}, and is usually stored as a 128-bit integer.

The primary purpose of the GUID is to have a totally unique number. Ideally, a GUID will never be generated twice by any computer or group of computers in existence.

The total number of unique keys is 2128 or 3.4×1038 - roughly 2 trillion per cubic millimeter of the entire volume of the Earth. This number is so large that the probability of the same number being generated twice is extremely small, and certain techniques have been developed to help ensure that numbers are not duplicated.


There are several ways of getting the GUID of your computer:

Via the OfficeScan server web console

  1. Log on to the OfficeScan server web console.
  2. In OfficeScan 10.6, go to Networked Computers > Client Management. In OfficeScan 11.0 amd 12.0, go to Agents > Agent Management.
  3. Highlight the group or domain and you should be able to see the GUID column which contains the information for each computer.
