Hello, using outlook 2003, exchange 2003 and AD 2003 with 7 domain
controllers. Is there a way to force the outlook client to authenticate with
a particular dc? We have a support account that many users send on behalf
of. Recently this started to not recognize recipients in our AD...we get an
undeliverable saying the recipient doesn't exist. However, we are also
having KCC errors and are going to transfer domain roles this
weekend...unrelated issue and the timeframe for NDR's doesn't fit, but I'm
ready to try anything. thanks in advance,
 
HKEY_CURRENT_USER\Software\Microsoft\Exchange\Exchange Provider
Value name: DS Server
Value type: REG_SZ

Use FQDN for GC server. Example;
exchange.domain.com
