Exchange in DMZ doesn´t authenticate on PDC in Intern zone

slemm over 23 years ago

hello,

I have a problem with my exchange 5.5 in DMZ
scenario is :

Intern zone with PDC - extern Zone Provider - DMZ with Exchange.

IP is fine, extern mail arrives through SMTP-Proxy (ASL) correctly, but Exchange in DMZ can´t log / authenticate on PDC in Intern-zone. Nothing in Live-Log, netbios and IP works fine.

Is it a MICROSOFT problem ?
anny suggestion welcome.....
