We have a simple Exchange 2007 setup with Mailbox, Hub Transport, CAS and Edge Transfer. The Edge Transport server is located outside AD in a DMZ.
My problem starts 24 hours after successfully configuring the edge-subscription as per Microsoft's guidelines on technet... I get InvalidCredentials and the synchronization fails.
It looks to me like renewal of the bootstrap-synchronization account fails.
How can this happen? Why does it happen? I can't find anything wrong with the setup or the subscription. It works excellent for 24 hours, but fails. When I renew, it works for 24 hours again.
Mostly Windows Server 2008 x64, some Windows Server 2008 R2 x64 in the setup.
Could use some input on this error. Anyone experienced this before?
