Re: Change control is good - when it is properly controlled
I remember installing DecNet S/W on an HP-UX box to communicate with a VAX. DecNet packet addressing was based on the assumption that all the NICs were Dec and so had the same MSBs. in the MAC. In order to work the S/W changed the HP MAC to look like a Dec with no warning. This rendered all the users' caches invalid and broke their connections. Fortunately this was in the days of character-based applications with client and RDBMS running on the same box so there were no database connections broken and the user PCs caught up with the change of address pretty quickly.
