Edit: We need Windows 2003 hosting with Sql Server storage.
A search for Windows 2003 in Shared and Reseller Hosting Offers produces quite a few results. Note that hosts cannot make offers in the main forums, and members aren't allowed to recommend a company that they don't have personal experience with. But when you find names of hosts that look suitable to you, you can search for reviews on them and ask for comments, as you did with boundgrid.net.
Do you have a WHT question or concern? Please open a helpdesk ticket.
