AD Topology / Config problem ?

Folks

I am taking care of a pretty standard Windows 2003 domain with a PDC, a BDC, an Exchange server and obviously some client systems (Vista / W7).

As far as I'm aware everything is working fine.

Recently however we had a hardware problem on the PDC and much to my surprise nobody could log on during the time it took to repair it - the error message being that there was no domain controller available to authenticate the user.

I would have thought that the BDC would take over for this task so there is clearly something wrong with the setup.

Where should I start to diagnose this issue ?

Any suggestion welcome

Do your clients have another DNS server listed in their config?  Are the other DCs also global catalogs?

Thanks

Yes both DC are also DNS servers and are listed on the client machines

>  Are the other DCs also global catalogs?

How would I go to check this ?

a lot of ways to check, sites and services and dsquery are two ways (see screenshots).  There are a lot of other ways too.

Thanks'
