Do you have a dedicated PDC or is it one of the Exchange Servers? On the double-take configuration are you failing one exchange server over to another or do the exchange servers failover to a dedicated target server?
I don't know if Microsoft certified double-take or not but I know it works very well. todd >>> [EMAIL PROTECTED] 02/13/02 08:34AM >>> Do not.. REPEATE DO NOT!!! use any clustering product, backup product, server mirroring product UNLESS IT HAS BEEN CERTIFIED BY MICROSOFT TO BE COMPATABLE WITH EXCHANGE!! Even Microsoft's own clustering product doesn't work infallably with Exchange. I doubt that this product has been tested with Exchange.

Everything is fine and dandy until I test the failover. The #2 machine takes over the identity of the #1 machine. This works fine, what doesn't work is the login to the domain. I lose my domain login and in result cannot pass email over the network. When I try rebooting the #2 machine (now #1) the domain says the account doesn't exist. I have inherited this network and the domain was setup already. I don't know much about how the domain works. Servers = NT4.0 compaq proliant SP 4 exchange = 5.5 The odd thing about this situation is that I aslo have two other servers running double-take, although not on ecxhange, and they work fine when failed over and failed back.
