My company is in the process of upgrading our exchange server from 2003 to 2010.
As part of the process we set up a dev environment in which we have a VM of our production 2003 server a VM of our new 2010 exchange. We created a VM of our domain controller which was on server 2003 has been upgraded to server 2008 R2.
We seem to be running into an issue with the 2003 exchange server, it is losing the trust with the domain controller and and we can not do a mailbox move from the 2003 database to the 2010 database.
In the environment i described how do we prevent our old 2003 server from losing the trust relationship with the domain controller?
I should point out that the dev environment is setup using vmware server and all machines are set to host only
