Is there any scanner for recognition of the type of database server of a site? I wanted to use Absinthe and it wanted to know if the server was my sql server, oracle RDBMS, postgrade sql and or Sybase?

To be special what do you think about the following server's database:
Server: Microsoft-IIS/6.0
X-Powered-By: ASP.NET
X-AspNet-Version: 1.1.4322
Location: /myaccount/default.aspx
Set-Cookie: cMemberCredentials=3i444iLzTnM%253d; expires=Thu, 24-Sep-2009 23:04:17 GMT; path=/
Cache-Control: private
Content-Type: text/html; charset=utf-8
Content-Length: 22340

From nmap I know that the OS is windows 2003 sp1(if I remember correcly)
