I inherited a domain that does not have a standard FQDN
The domain is name "xyzdomain"
The NetBIOS domain name is "xyzdomain"
The DNS domain name is also "xyzdomain"
The domain does not have an extension like .local or .com
We want to change to domain so it will keep the same NetBIOS name but we will rename the FQDN to "xyzdomain.com"
I know that some application like Exchange 2007 and later does not support this operation and they are running a blend of Exchange 2003 and Exchange 2007 servers.
Since we only want to change the FQDN name and keep the same NetBIOS, What will be the impact ?
They only have 2 DC, and about 12 other servers and about 10 computer for users
