setup: migration from exchange 2003 to 2010 done and running fine for several weeks.
on old server 2003 running Exchange 2003 un-install failed ( as usual) so manual cleanup required.
All i have left is this entry in ADSI ( on the server 2008)
at present ADSI has:
CN=Exchange Administrative Group (FYDIB0...... <-present working Exchange 2010
CN=First Administrative Group <-old exchange 2003
Can I simply delete the whole container for CN=First Administrative Group
or only the server reference in it?
