*Have migrated from Exchange 2003 to 2010 (2003 was on a domain controller) - things "seem" OK i.e. running since mid July.
*Uninstalled Exchange 2003 (used http://technet.microsoft.com/en-gb/library/gg576862(v=exchg.141).aspx
*Want to demote the old Exchange 2003 server from being a domain controller. Was suspicious things might go wrong so just turned it off for a couple of days to see if anything broke
*Not definitely related to the turn off but very coincidental otherwise, once turned off users with Outlook 2007 on Win7 had Outlook, Acrobat and Word etc. hang/crash when opening attachments.
*Turned back on and all OK again
Is this related to the fact that there are still Exchange 2003 things in Active Directory? i.e. in ADSIEdit I still have Configuration>Services>Mic
rative Groups>First Administrative Group
If so how do I get rid of those? ADSIEdit?
If not what else could be causing this?
