I have a single Exchange 2003 server.
company.local (NETBIOS--DOMAIN) subdomain.company.local (NETBIOS--SUBDOMAIN).
My network admin was recently laid off so I changed Administrator password for DOMAIN and SUBDOMAIN. Since the change users that log into SUBDOMAIN are unable to log into OWA.
The user are using the form SUBDOMAIN\username and entering their domain password which worked prior to the password change. Error Message: You could not be logged on to Outlook Web Access. Make sure your domain\user name and password are correct, and then try again.
Users who log into the parent domain are able to logon using DOMAIN\username.
