Upgrading a Single Copy Cluster to Exchange 2007 SP1

Upgrading the Exchange 2007 single copy cluster requires a bit changed steps than in previous Exchange Server's releases. You still have to work on a passive node tough :)))

I suggest that you run Microsoft Update on all nodes prior to Exchange SP1 install. The most important part is .NET Framework 2.0 SP1 update, since Exchange is .NET Framework application!

The change from previous versions is that there is no GUI for updating the cluster. You have to do the upgrade from command prompt.

Let's presume that our nodes are named NODE1 and NODE2. Steps are as follows:

On NODE2

  1. Move all cluster groups to NODE1 if they are not already active on NODE1
  2. Put Windows Firewall/Internet Connection Sharing (ICS) service to manual and then START IT, since Setup will add Windows Firewall exceptions for Exchange services
  3. Stop any services that have open handles to performance counters (Performance Logs and Alerts and any Microsoft Operations Manager agents), since performance counters are changed during setup
  4. Stop, and then restart the Remote Registry service
  5. In command prompt navigate to Exchange 2007 SP1 files and run (files must be available locally):
Setup /m:upgrade
  1. Restart NODE2 after setup completes
  2. Open Cluster Administrator and take Exchange Server's Group OFFLINE !!!
  3. Move all Groups to NODE2 (THIS SERVER)
  4. In command prompt navigate to Exchange 2007 SP1 files and run:
Setup /upgradecms
  1. After this completes Exchange Services on NODE2 are started and you are ready to move to NODE1

On NODE1

  1. Put Windows Firewall/Internet Connection Sharing (ICS) service to manual and then START IT, since Setup will add Windows Firewall exceptions for Exchange services
  2. Stop any services that have open handles to performance counters (Performance Logs and Alerts and any Microsoft Operations Manager agents), since performance counters are changed during setup
  3. Stop, and then restart the Remote Registry service
  4. In command prompt navigate to Exchange 2007 SP1 files and run (files must be available locally):
Setup /m:upgrade
  1. Restart NODE1 after setup completes
  2. Move all cluster groups back to your preferred active node

On NODE1 and NODE2

  1. Stop and disable the Windows Firewall/Internet Connection Sharing (ICS) service on both nodes.

Netscaler vs Exchange 2019 "time out during ssl handshake stage

If you are using Citrix Netscaler as load balancer in front of Exchange 2019 server you must know this: Microsoft Exchange 2019 is secured by default and allows only TLS 1.2. Therefore default schannel settings are as follows (using IISCrypto tool from Nartac Software): While Citrix Netscaler offers following Cipher Suites: TLS_RSA_WITH_AES_256_CBC_SHA TLS_RSA_WITH_AES_128_CBC_SHA TLS_DHE_RSA_WITH_AES_256_CBC_SHA TLS_DHE_RSA_WITH_AES_128_CBC_SHA TLS_DHE_DSS_WITH_AES_256_CBC_SHA TLS_DHE_DSS_WITH_AES_128_CBC_SHA TLS_RSA_WITH_DES_CBC_SHA TLS_RSA_EXPORT_WITH_DES40_CBC_SHA TLS_RSA_EXPORT_WITH_RC2_CBC_40_MD5 TLS_DHE_DSS_WITH_DES_CBC_SHA TLS_DHE_DSS_EXPORT1024_WITH_DES_CBC_SHA TLS_DHE_DSS_EXPORT_WITH_DES40_CBC_SHA TLS_DHE_RSA_WITH_DES_CBC_SHA TLS_DHE_RSA_EXPORT_WITH_DES40_CBC_SHA TLS_RSA_EXPORT1024_WITH_RC2_CBC_56_MD5 TLS_DH_anon_WITH_DES_CBC_SHA TLS_DH_anon_WITH_AES_128_CBC_SHA TLS_DH_anon_WITH_AES_256_CBC_SHA TLS_DH_anon_EXPORT_WITH_DES40_CBC_SHA Now, you will fi

Change SMTP port 25 in Exchange 2007, 2010

For some reason you might want to change default SMTP port number 25 Exchange 2007 is using. Exchange 2007 uses RECEIVE AND SEND connectors, one for receiving mails and other for sending mails (obviously ;) So you need to change ports on those connectors. I will not say those two, because you might be using more than two. You change Receive connector port by opening the connector properties in Exchange Management Console --> Hub Transport --> RECEIVECONNECTORNAME --> Properties --> Network --> Local IP Addresses (Edit Receive Connector Binding) Just to clarify what "Local IP Addresses" and "Remote Servers" are (from Exchange 2007 help), because I find it little bit confusing: Use these local IP Addresses to receive mail Use this list to specify the IP addresses and port numbers on which this Receive connector listens for incoming mail. Receive mail from remote servers which have these IP addresses Use this list to specify the

Exchange Admin Center language

Depending on your computer language settings, Exchange Admin Center can take those and open in a language you actually don't want to use. You'll Google that this can be changed if administrator/ admin user has mailbox by openening OWA settings and changing Regional parameters. But usually Admin user does not have mailbox or you don't want her/him to have it. You will search again and find that you can add mkt=en-US (as an example) to the URL of the Exchange Admin Center (https://yourexchangehostname/ecp?ExchClientVer=15&mkt=en-US) Third option you have is opening Internet Explorer settings (I am using Windows 2016) Click languages Click Set Language Preferences Add language you want to use by clicking Add language Use Move up or Move Down options to put desired language on top Close Internet Explorer Open it again and login again to Exchange Admin Center
