Discovery Wizard for SQL Server not detecting all SQL servers and instances in a domain, only 1 out of 4

Hi, I downloaded and setup Discovery Wizard for SQL Server, version 3 beta. When I run a domain scan it discovers only 1 single server with 2 instances and not the 3 other sql servers I have in my domain. I tried by IP Range but it errors and shut down the application

No Sir, no firewall nor subnets. When I search by specific IP  it finds the sql server, I can ping all machines. Also, while searching, I get error message boxes "object instance can not be null " and it continues.

Do you need any of the other nonsense which DW does? If all you need is a list of instances, there's quite a useful script knocking about which uses the SQLDMO object to get that. Alternatively, you can use plain old WMI.

What a wasp nest this could be! Sub-nets...firewall...are the boxes PINGable, for example?
