Question : How to remove Exchg 5.5 from Exchg 2003 envoriment?

I migrated from Exchg 5.5 to Exchg 2003. The Exchg 5.5 server crashed before I could remove it. Is there a way to manually remove it? I have to change to native mode in order to upgrade to Exchg 2010.

You will need to remove it manually using ADSIEdit.

Under Configuration > Services > Exchange Services > Org Name > Administrative Groups > Admin Group Name > Servers

Select it and delete it.  DO NOT delete anything else.
