My Exchange2003 server is clustered on Veritas Cluster Services. OS = Windows2003 R2 Exchange = win2003 My users are able to access Exchange Server via MS Outlook but not able to access there emails via OWA. Users get message "ERROR ACCESS IS DENIED" after asking authentication window three times. I also tried to follow the below articles but unable to get success. http://support.microsoft.com/default.aspx/kb/250657?p=1 http://support.microsoft.com/default.aspx/kb/317471?p=1 http://support.microsoft.com/default.aspx/kb/287726?p=1 (from this 3rd article i am not able to find the ADVANCED TAB in point4 in this document)Haseeb

Hi, What’s the configuration of your exchange cluster? Is it a CCR or LCR cluster? Is your external URL redirected to virtual node server or physical server ? Have you tried to access exchange server by http://<FQDN of a node >/exchange? Does the issue persist?

I am using Veritas Cluster with disaster recovery setup (sfha /DR) with version 5.0. What configuration you are needed (i mean what is CCR or LCR cluster )? I tried to access via http://FQDN/exchange and i also tried via http://ipaddress/exchange but not successful. This problem i am facing at secondary site cluster but my primary site cluster is working fine as i have already told you dear. Any comment will be appreciated ________________________________ Thanks Zahid Haseeb zahidhaseeb.wordpress.com

Hi, CCR is Cluster Continuous Replication, LCR is Local Continuous Replication. I recommend you first check if Exchange Virtual Directory path is correct: 1. On Exchange 2003 server, Open IIS, click web sites->Default Web Site->Exchange. 2. Right click Exchange and choose properties. 3. In Virtual Directory tab, select "A directory located on this computer". Make sure the Local path is \\.\BackOfficeStorage\domain.com\MBX Note: domain.com is your internal domain name. 4. Run IISreset 5. Restart the following services: Microsoft Exchange information store World Wide Web Publishing Service

Thanks thomas for your kind reply I checked the below setting which you told me. I found that samething at my DR Site ======================= 3. In Virtual Directory tab, select "A directory located on this computer". Make sure the Local path is \\.\BackOfficeStorage\domain.com\MBX ========================= Any comment will be appreciated ________________________________ Thanks Zahid Haseeb zahidhaseeb.wordpress.com
