Hello,
We have just created a new tree / subdomain into exitsing forest and have installed exchange 2010 on a memeber srever.
Everything seems to be working expect for the SMTP service on exchange 2010, email cannot be received. We can telnet to port 25 but pressing enter or helo times out the connection.
mail troublshooter has came back with error
the computer account for "SMTPSVC/servername.domain" wasnt found in active directory.
No computer account in Active Directory has "ServicePrincipalName" Set to "SMTPSVC/servername". This will result in Kerberos authentication failures when server .... attempts to create SMTP connection to another Hub transport srever.
