I'm on a Private Label Reseller plan on a Linux server.
I have a prospective customer who wants his website on a Windows server.
What would be the best option being in mind he only needs 100Mb of space?

We can split your reseller account on two servers.

Or setup a new account for your client and decrase your reseller allocation according on it.

WHOW !!!!!!!!!! These are really good news!!!
in the past stanly say me than the only option is buying another p.label reseller account in windows !!

yeah!!

(the nameservers will be the same ? or he need use hostony name servers ? or buy another 2 dedicated IPs for new name servers ?)

You can use any option

As I read this I wonder... why am I paying for both a Linux Reseller plan and Windows Special plan to be able to resell both Windows and Linux accounts?

Please contact our sales department if you don't want to pay for both a Linux Reseller plan and Windows Special plan to be able to resell both Windows and Linux accounts.
