Hi,
You can add the second server as a domain controller which would make AD fault tolerant (but not fully due to FSMO roles). Make sure that this second server is also a Global Catalogue. To upgrade this server to a DC use DCPROMO from the run prompt.
Make sure that DNS is AD integrated and then install DNS on the second server - it should then replicate from the first server. Then add this DNS server as a secondary DNS server in your DHCP scope options. That's DNS sorted and failing over if needs be.
DHCP can be made fault tolerant by splitting your scope in half (make sure that there are enough addresses in both halves to cover ALL of your machines). Put the second half of your scope onto the second server, activate the scope and authorise the server in AD. Both will answer queries for DNS but if one fails the other will work providing fault tolerance.
For your files and roaming profiles you could just have some sort of batch routine or backup that copied all the files to the second server overnight, giving you an up to date copy each night. A better (but much more expensive option) would be to install a NAS (network attached storage) solution. This would put all of your data in one place (a very large RAID 5 for example) and you could update your PC's to look at these shares rather than the server's shares. This way, either server can access the data, providing fault tolerence as requested.
Failing that there are some software solutions that will update other machines with up-to-date copies of the files. Something like Veritas/Symantec Volume Replicator. Take a look at this here:

Hope that helps,

Hi daspug,

i tray to runing DCPROMO , but i have this problem now :


The error was: "DNS name does not exist."
(error code 0x0000232B RCODE_NAME_ERROR)

The query was for the SRV record for _ldap._tcp.dc._msdcs.uicc0.local

Common causes of this error include the following:

- The DNS SRV records required to locate a domain controller for the domain are not registered in DNS. These records are registered with a DNS server automatically when a domain controller is added to a domain. They are updated by the domain controller at set intervals. This computer is configured to use DNS servers with following IP addresses:

192.168.91.2

- One or more of the following zones do not include delegation to its child zone:

uicc0.local
local
. (the root zone)

For information about correcting this problem, click Help.

Can you help me ?

thanks
