If i have 2 NT servers ( pdc , bdc )is there any easy way to make sure that data on one is copied or mirrored on the other?
I am looking for a DFS type of a solution.
I want the backup server to pick up the workload at once and for it to be extremely reliable.
second priority is load balancing - is there any way to put it into the fallover solution?
both servers are nt 4 sp6.
Please give a description or point to an article ora book.
( note: I have heard that dfs in nt 4 really does not work? )

Hi,
their are many solutions to your Problem, i will try to explain three of them:

1.) Vinca CoStandBy Server
It is a Software Solution for Clustering to Nodes in Active/Passive or Active/Active config. The Cluster Model is the Nothing Shared modell, like MSCS. The two nodes got their own harddisks, vinca mirrrors them over an dedicated connection named Vinca-Link. More Infos under : Http://WWW.Vinca.COM

2.) Octopus
A variety of features make Octopus an effective complement to any fault- tolerance or disaster recovery contingency.
Octopus processes replicate open files providing continuous backup, protect against inadvertent file deletions, include flexi-
ble and multiple location options for replicated data, and captures and updates data to targets in real- time. Octopus even
allows user to maintain access to Applications and files during
tape backup procedures. Octopus is the most efficient choice for complete data protection. Www.Legato.com

3.) Secure Copy
Copy your File Server Data witht ACL and the Shares to different Server.

Yes it was very helpful and probably i will implement co-standby server ( pricey = around $5000 ) but i heard it is worth it.
pity they don't have it ready for win2k yet
thanks
