I appreciate your quick response.
But I am afraid, it didn't answer my question, may be I was unclear. Anyways, I build servers remotely and the requestor/end user wants the DNS names to be in lowercase, cause these kind of requestors wants to install SAP on their own and say some functions would fail should the DNS or NetBIOS names are in upper case, hence, they want us to build the servers Hostname, DNS names and NetBIOS names in a lowercase.
Out of these three, DNS names is the most required thing as per their requirement..

I have written a detailed description of the workings of NetBIOS over TCP
(NBT). You can find it here: http://ubiqx.org/cifs/NetBIOS.html
In general, NetBIOS names are converted to upper case before use by the
underlying system. This is not a requirement, but it is common practice.
DNS names and, therefore, hostnames are supposed to be compared "in a
case-insensitive manner". Converting NetBIOS names to upper case produces
the same effect.
In general, it's not something you have to worry about. The only time this
causes trouble is if an application fails to convert the NetBIOS name to
upper case before encoding it. Such problems are rare, and I doubt you will
have any problems unless you are writing your own NBT implementation and
forget this step.
Let me know if that answers your question.
PS. Note that you did send your query to the Samba-Technical mailing list,
and not directly to me. That's okay, it's appropriate for the list,
but your message suggested that you intended to send directly to me.
