Windows 2003 Server
DotNetNuke Install package 5.1

On intial install of 5.1. When running through the install wizard at the host user account setup I get an error and cannot conitnue.

Host User Error:
Length cannot be less than zero. Parameter name: length

Has anyone experienced this and how to resolve?

I've tried setting IIS authentication for the website to just be anonymous (as per other forum suggestions).

Thanks,

David.

I just installed 5.1.4 and I am having this same problem on the STMP setup step.  The Test button comes back with success, and I can see in my mail server logs where the e-mail test worked, but when I click Next, I get this "Length cannot be less than zero" error.

Any ideas why this is happening or what I need to do to fix it?

Thanks
