DC in domain

[mk001]

Hi all,

I have question of domain controller. I setup 3 domain controller(say srvA, srvB, srvC all is windows 2000 server) in one domain. srvA also act as DNS server. The srvA is upgraded from NT4.0 PDC, srvB is only domain controller, srvC is email server(exchange 2000).

I found that if srvA is down, srvB and srvC cannot work normally. The user cannot login the domain and cannot use email server. I think that the problem due to srvA is primary domain controller (PDC) in domain. srvB and srvC depend on srvA to work normally.

How to make user can login domain and use email server when srvA is down?

thanks

make either srvB or srvC the backup domain controller

There are no PDC's nor BDC's anymore, period. There are role holders, but you have to get out of the mindset of PDC's and BDC's.

Make server A and server B GC's, setup DNS on both as well.

There are no more PDC's! There are DC's with FSMO roles!

thanks all reply,

I know that there has been no PDC and BDC concept in active directory. However, srvB and srvC cannot work normally when srvA is down.

If I setup one more DNS in srvB, the srvB and srvC will work normally when srvA is down?

What is meaning of “GC”?

Thanks,

hi all,

i had checked that GC is global catalog. if i only check the GC box and add DNS in srvB and point the IP of DNS in svrC to svrB, it will work under srvA is down?

thanks,

You make both A and B GC's and run DNS, then point server C to both for DNS (primary A, secondary B). Advertise both in your DHCP scope as well.

thank for your reply.

i had set the enviroment to test it. it's ok now. i also point server B to both for DNS (primary A, secondary B itself).

thank you.

hi,
when you migrate a NT4 domain to 2000/3/8, it is good to remove migrated server (A) from domain (demote it), after
have moved FSMO on (B) and tested all is good, becouse directory structure is different between 4 and 5. Then reinstall (A) from scratch in 2000, or better in a new HW.
