This error seems to appear on W2K3 R2 Server. Solution is simple:
Go to add/remove windows components, then uninstall the Internet Explorer Enhanced Security.

Eroarea zice:

The Active Directory Installation Wizard cannot continue because the forest is not prepared for installing Windows Server 2003. Use the Adprep command-line tool to prepare both the forest and the domain. For more information about using the Adprep, see Active Directory Help.

The version of the Active Directory schema of the source forest is not compatible with the version of Active Directory on this computer.

Si apare in momentul in care incerci sa adaugi ca DC o masina pe care e instalat Windows Server 2003 R2.
Ea apare din cauza ca pe masina "schema master", "schema version" (lol) este 30 (versiunea originala de la 2003 SP1) in loc de 31 cate e pe 2003srv R2.
Pe schema master se ruleaza adprep de pe discul 2 de Windows 2003 Server R2.
run: \CMPNENTS\R2\ADPREP\adprep.exe /forestprep
Pe urma se ruleaza dcpromo in mod normal de pe masina cu 2003 R2.
PS: Versiunea de pe schema master se poate verifica din reg:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\NTDS\Parameters
cauti Schema Version (30 sau 31), ma rog...sau 13 (Win 2000).

Acum cateva zile, in urma unei instalari pe unul din serverele 2003 din domeniu, a trebuit sa dau un restart serverului respectiv. Problema e ca serverul e cam la 430km distanta si nu aveam acces fizic la el. OK, nimic nou...totusi serverul nu revenea din starea de "amorteala" in care l-am bagat.
De ce nu a pornit?
El saracul a pornit. Dar in urma unei verificari ulterioare s-a dovedid ca IPSEC a intrat in "block mode" si nimic nu mai misca pe acel srv.
Eroarea arata cam asa:

The IPSec driver has entered Block mode. IPSec will discard all inbound and outbound TCP/IP network traffic that is not permitted by boot-time IPSec Policy exemptions. User Action: To restore full unsecured TCP/IP connectivity, disable the IPSec services, and then restart the computer. For detailed troubleshooting information, review the events in the Security event log.

Rezolvarea este simpla (sau cel putin asa sper eu):
Te duci aici: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\IPSec\Policy\Local, stergi cu totul cheia si subcheile din Local si pe urma Start>Run>regsvr32 polstore.dll.
Cam atat.
Ah, event id-ul e 4292, avand ca sursa IPSec.
