Novy GPO serial

October 6th, 2011 2 comments

Coraz viac zistujem, ze lokalni administratori vo firmach nerozumeju GPO a preto ich nepouzivaju. A ked ich aj pouzivaju, tak im vacsina aj tak nerozumie. Preto som sa rozhodol o napisanie serialu o GPO politikach a spravit tak osvetu v tomto smere.
Tak mi drzte palec. Dufam, ze sa bude pacit.


Obsah serialu:

#1 GPO Serial – Lokalne Politiky
#2 GPO Serial – GPO v domene cast 1.
#3 GPO Serial – GPO v domene cast 2.
#4 GPO Serial – Aplikovanie GPO
