xcomiiiCommented:
Exchange Trusted Subsystem is a computer group, and your existing exchange servers are member of that group. Try to add the dc.geo.com into the group.

Ali Are you reading me

1) You should NOT create an alternate share witness
2) The machine hosting the sharewitness should NOT be part of the Exchange Trusted Subsystem
3) the Exchange Trusted Subsystem should be in the local admin of the share witness server
