Hi All,
I am desperate having a serious issue with my POP3 clients. At times clients are able to send mail and at times not able to. But they always receive mails.
I have published OWA, OA, POP3 587 and POP3 995 on ISA 2006 SP1.
I have 2 Exchange 2007 Ent. SP1.
My internal server kwmail.path.local holds the all the roles except Edge. Edge is in the DMZ.
My Public domain is path-solutions.com.
My public DNS zone is on the Edge Server behind the ISA and port 53 from Edge also published on ISA.
I am using self generated certificates from MS PKI.

I want to use https://kw.path-solutions.com as my url for all CAServices.

I have generated the certificate for internal server as given below:
new-ExchangeCertificate -GenerateRequest -Path c:\certificates\kwmail.req -SubjectName "c=KW, o=ICT Professional Services, cn=kw.path-solutions.com" -DomainName kw.path-solutions.com,kwmail.path-solutions.com,kwmail.path.local,kwmail -PrivateKeyExportable $true

import-exchangecertificate -path c:\Certificates\Issued_cert_for_kwmail\DerEncodcert\kwmail.cer | enable-exchangecertificate -services "SMTP,IIS,POP,IMAP,UM"

On the ISA I see the below error:

Upstream Chaining Credential
Description: ISA Server was unable to establish an SSL connection with kwmail.path.local. A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

If I check the certificate on kwmail.path.local, in the, details, Subject Alternative Name field I see a warning on the left side.
I suspect this is the cause of SMTP 587 port on ISA behaving inconsistent.

Any help appreciated. This is in production and staffs all around the world calling and shouting at me. Please help me
Regards
Liby
