Using 5.02.00 (275) on Windows Server 2008 R2.  IIS is set to Anonymous access.

Getting this error at the SMTP screen:

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

There is a message on this exact issue in this forum, but no solution was posted.

Any ideas on how to get past this?

Thanks in advance,

Charles

Issue turned out to be Network Services did not have rights to the subdirectories where DNN was installed.  Once I fix that, the install went with out a hitch - but I did have to delete all of the files from the install and reinstall all files to the DNN directory, as well as start from a blank database.

I get the same issue on 5.5 prof - i reinstalled no help. I am unable to bypass smtp and I am using costom install.

seems that nothing i put in smtp settings is accepted. Note that the smtp server is anonymous

here is the error

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