Tony, yes you are correct.
The "corp" os for corporate use, where we use 1 CD to install on X numbers of computers, using 1 key.
We are charged for the number of reported licences used, and since some of the computers are strictly used in an offline environment
they become activated by the files on the CD and the key used.
No need to call MS, or go online.
@Leech
Then I guess *you* had a bad copy of DO, probably burnt at >4x known to cause those probs.
I and many others, have compared DO with the legit corp ( VLK ), and we find 0 ( zero ) differences
in files, dates, CRC, hash, MD5... whatever
And I know it has been used in some companys, when they did not find the legit CD, so they used DO and the legit key.
