We currently have old Dell servers with Widows 2003 standard installed on a domain controller/active directory box that is file server, also on another that is Terminal Server and finally on a separate server running Exchange 2003. We had not had any issues with email until we needed to add a new user this week and found that since we last added one in November last year, we are unable to add the user in the Exchange Server's active directory. We can create the user on the domain controller for all other network use but not on Exchange to give them email.
We are going to new servers with Windows 2012 and Exchange 2010 but did not plan on it until next month. (June)
The old Exchange 2003 server was low on disk space and we moved everything we could off of it and it has been running email fine as mentioned. We are afraid that someone moved something necessary for active directory and Exchange Extension or something is corrupted in the system somewhere.
When we go into Active Directory users and computers under start-programs-Exchange we can see all the users fine. if we right click on the user created in the domain server we get box that is titled "Microsoft Active Directory- Exchange Extension" in it it has this
Microsoft Active Directory- Exchange Extension
we click ok and it stays in the AD Users and Computers. we can then right click again and if we pick "properties" we get a box titled "Snap-in Error"
with the following:
MMC has detected an error in a snap-in. It is recommended that you shut down and restart MMC With option to report the error to MS or ignore and continue running.
We can do some other things when right click like change password for user etc. So it appears that Exchange Snap-in or AD Extension is corrupt???
I am at a loss as to what to try at this point. We need the new user to get email asap and we don't have the time to setup three new servers in the next day or so.
Our plan for new servers is to set them up as complete new network and just copy over data, doc. xls files and accounting data etc and reinstall the accounting apps. We won't try to migrate from old Exchange 2003 even if it were working correctly. We plan to export the PST files for each user and then import them into outlook and new Exchange 2010.
There are only 18 users so it will be a pain but not overwhelming.
Any suggestions on what to do with the old Exchange 2003 to figure out how to repair and get a new user setup so that we can calmly go about the new network setup over the next few weeks when we have time?
