Hello. We have a new server deployment with Windows Server 2003 Standard and Exchange 2007. We had exchange 2007 all setup and working. Mail was flowing to the internet from the exchange server/clients and all was well. Then, all was not well. Now, it seems as if we don't have any permissons to access hardly any of the features of Exchange. When I open Exchange, I am greeted with the following error when I click on Exchange Configuration in the tree view of Exchange Managment Console:
"You do not have permissions to read the security descriptor on CN=SERVER1,CN=Servers,CN=Exchange Administrative Group (FYDIBOHF23SPDLT),CN=Administrative Groups,CN=First Organization,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=ourserver,DC=net. It was running command 'get-ExchangeAdministrator'.
As I said everything was working until we installed Office 2003 on the server. That's the only change that was made after the Exchange Server was successfully working.
A little background on the server:
Several different technicians have worked on this server. It's current name SERVER1 was used when it was first built. The name was changed at one point to something else after Exchange Server was installed the first time. After changing the name back Exchange began to work. However, a software installation was performed for some customer software and that software installed a 32-bit version of .Net Framework and broke Exchange. .NET was completely removed (all versions) by the removal tool available from Microsoft and Exchange was completely (and forcibly) removed. .NET framework was reinstalled (one version + patches at a time) and then we reinstalled Exchange Server and setup all the users and everything was great until (we're assuming) Office 2003 was installed.
More information: Not only do we get the error above, but we can't access much of the Exchange Management Console. The send connector area is blank as is Offline Address Book and a lot of other areas. We can see all of the user mailboxes and they are able to store mail in them (the server is only used as storage right now with the users POPing their mail as we haven't set it to host it's own mail yet due to these problems), but we can't add mailboxes, change them or do anything in the console.
Thanks for your help,
