Exchange Server stores messages in a mailbox database residing on a mailbox server. However, this is the only significant data that is stored locally on Exchange Server. All of the Exchange Server configuration data is stored within the Active Directory.

In fact, it is possible to completely rebuild a failed Exchange Server from scratch aside from the mailbox database simply by making use of the configuration data that is stored in the Active Directory. The reason why I mention this particular example is that the Exchange Server configuration data is stored within the computer object for that server.

In other words, getting rid of a computer account can cause some pretty serious problems for your applications.

A better approach is to simply reset the computer account. Right click on the computer that you are having trouble with.
