How to configure server redundacy ? Stratos 07.07.2007 19:24:01 Hello ! I have Win2003R2 server running DHCP, IIS and applications: Syslog, TFTP, Time server. Have an idea to buy a similar server and make full server redundancy. It means that the second server should monitor primary server for failures and take the role of primary if it does not responds. At time when failover occures the standby server should have all DHCP, IIS records/configs and recent files from primary server. Also if it is possible the standby server should take the same IP address as active server. Need detailed guide how to configure both server ? Thanks for help.

For fault tolerance just use 2 DC's, both with DNS active directory integrated, both Global catalog and configure a 80/20 or 70/30 DHCP scope so that if you have a failure DHCP is still handing out addresses, until you activate the rest of the scope to the running DHCP server. For file redundancy you can configure DFS with two folders with the same content that replicates the changes: http://www.microsoft.com/windowsserver2003/technologies/storage/dfs/default.mspx http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=5e547c69-d224-4423-8eac-18d5883e7bc2 Best regards Myweb Disclaimer: This posting is provided "AS IS" with no warranties, and confers no rights.
