In echipa de Active Directory tratam, printre altele, si replicarea DFS. In aceasta privința recomandam tuturor clienților sa instaleze ultimele hotfixuri pentru DFS-R, daca folosesc aceasta funcționalitate. In acest articol voi lista cele mai importante hotfixuri.

Deoarece aceste hotfixuri rezolva probleme care ar putea apărea intr-un mediu DFS-R, este recomandat sa fie instalate pe toate serverele de DFS-R. Niveluri diferite de hotfixuri nu sunt recomandate in general, nu doar in legatura cu DFS-R-ul. Daca serverele au hotfixuri diferite instalate pot apărea probleme care sunt greu de urmărit si depistat. De aici recomandarea de a instala toate fixurile  pe toate sistemele DFS-R.

Deoarece majoritatea clienților folosesc DFS-R-ul in legătura cu DFS-N-ul, sunt listate si actualele hotfixuri pentru DFS-N. Suplimentar sunt listate si fixuri care sunt relevante atât pentru DFS-R cat si pentru DFS-N (de exemplu RPC-Hotfixes, SNP etc.). Lista poate sa nu fie completă, și are ca scop enumerarea celor mai importante hotfixuri.

O sa încercam sa ținem acest articol up-to-date, așa încât sa puteți afla daca au apărut noi fixuri printr-o simpla verificare a acestuia.

In mod normal fixurile pentru un service pack anterior sunt conținute în service pack-ul actual sau viitor, deci de exemplu fixurile post Windows Server 2003 SP1 sunt integrate in Windows Server 2003 SP2. Pentru Vista si Windows Server 2008 aceste limitări nu sunt valabile așa încât sunt listate (in cazul in care exista) atât fixuri RTM cat si fixuri SP1.

Deoarece unele hotfixuri pentru Windows XP si Windows server 2003 sau Vista / Windows Server 2008 se suprapun, nu s-a făcut o împărțire după versiunea service pack-ului. Este de ajuns sa aruncați o privire in articol pentru a afla daca hotfixul respectiv este necesar pentru sistemul de operare in cauza.
