Re: pdc to bdc

 

Hello tahreem,

 

Since windows 2000 there is not longer the PDC/BDC concept. So what OS do

you use? Since 2000 all DC's are the same, the difference are the 5 FSMO

roles, which can be hold by any available DC, with some rules ofcourse. One

is the so called PDCEmulator which is used the connection to NT4 domains.

If a DC fails, normally the first installed has all 5 FSMO roles and Global

catalog, you have at least the need for additonal Global catalog server and

DNS server if the DC is also the only DNS server and if you use DHCP from

that machine you also additional DHCP server.

Clients has to be configured to use both DNS servers otherwise they are not

aible to logon to the domain.

 

If a DC crashes and NEVER come back and this DC has kept any of the FSMO

roles you have to seize them to another DC BUT ONLY if the old DC never comes

back.

 

Additional you have to do a metadacleanup to remove it correctly from the

domain, otherwise you are having a lot of errors about replication in the

event viewer and are also not able to bring in a new DC with the same name.

 

Best regards
