Exchange 2003 upgrade to Exchange 2010 DNS record addition (DNS Robin method)

1. Because of the design requirements of Exchange 2010, we need to add the relevant DNS records and add the following records:

Automatic discovery is an automatic Outlook feature provided by Exchange 2007 and above, and if your Outlook is above the 2007 SP2 version, you can enjoy the flexibility that automatic discovery brings to your machine. So we add a Autodiscover record here:

Autodiscover.xxx.xxx CAS Server1

Autodiscover.xxx.xxx CAS Server2

Both Exchange front-end servers are currently registered and the IP address of the name of the CAS array we are about to create must point to both servers, so we created the CAS array with the name Exmail.XXX.XXX. We need to create two Exmail records at a time:

Exmail.xxx.xxx CAS Server1

Exmail.xxx.xxx CAS Server2

2. Trigger a copy, we use the command here: Repadmin/syncall
