    Hello,

    We currently have an Exchange 2010 environment with three CAS/HT servers. We just relized that two of the three appear to not be processing SMTP mail properly. Upon further investigation, we are unable to telnet to these servers from a workstation over port 25.

    Error Message:
    H:\>telnet DRexcas01 25
    Connecting To excas01...Could not open connection to the host, on port 25: Connect failed

    Does anyone have some suggestions on where I can start looking? All of the services are running just fine.

    You dont really need to suspend replication, just the automatic activation of the stores on the server you are upgrading.

    The only time its really necessary IMO to suspend log replication is if you are replacing the storage, or for perhaps troubleshooting some particular issue. Let the script do what it does and you will be good. But you can of course suspend log replication if you want, but not required when doing upgrades.

    For the other question, why do want the servers in the DAG to be at different levels? How long do you plan to leave them that way?

    Hello,

    I installed update rollup 4 for Exchange 2010 SP2 over the weekend and I think this has resolved my issue. I will apply the updates to the main Exchange servers this evening.

    Hi Jason,

    Mostly, this is a firewall issue. Allow the port 25 through firewall (test by temporarily disabling the firewall also) and test again

    Hello ManU,

    When you say firewall, do you mean on Windows or the organization's firewall? Also, do you think this error message may not be the issue below?

    Microsoft is recommending the installation of RU1 to resolve the problem but we already have this installed. I was thinking of installing update RU4 since it addresses some edgetransport.exe service crashes. I do have a few questions.

    We currently operate in a DAG. Two mailbox servers in our primary location and one mailbox server in the DR. I want to install the update RU4 on the DR servers first. Is there anything special I need to do to the DAG before starting the process? Should I stop the DAG replication to the mailbox server? Does update RU4 include the updates from RU2 and RU3? Thanks

    This answered one of my questions on how to apply an update RU to a DAG.

    Ok... answered another one of my questions but this issue is odd. I see now that I should place the DAG into maintenance mode.

    http://blogs.technet.com/b/mbaher/archive/2010/09/13/installing-update-rollups-on-database-availability-group-members.aspx

    I run the script (StartDagServerMaintenance.ps1 ) but it actually never pauses any of my database replications. It does place the DatabaseCopyAutoActivationPolicy to a blocked state. I have to go in and pause the databases manually.

    One last question. I know it is not advised but is it ok to have the DAG in the primary location and DR location operate on two different Exchange Versions?

    Primary Location (2 CAS/HT and 2 MBX) - Exchange 2010 SP2 with update RU1
    Secondary Location (1 CAS/HT and 1 MBX) - Exchange 2010 SP2 with update RU4

    Andy,

    Thank you very much for the information. We typically like to apply patches during our maintenance window but this SMTP mail flow issue has us in a bit of a bind. I really need to apply the update RU4 to the CAS/HT servers in hoping to resolve the issue. Could I just apply to the CAS/HT servers and wait until our maintenance window on October 13th to apply to the mailbox servers? Thanks

    Oh sure. You can do that. That will be fine.
