II6 On Server2003

I just started a new 2003 with II6 and can't get .asp
documents to function. I have enabled asp support. I
copied the web tree from a working IIS NT/4 server. The
following error message is logged in the IIS log:

2003-08-28 09:52:41 10.0.0.107 GET /dplogon.asp
|1|ASP_0134|Invalid_ProgID_attribute 80 - 10.0.0.107
Mozilla/4.0+
(compatible;+MSIE+6.0;+Windows+NT+5.2;+.NET+CLR+1. 1.4322)
500 0 0

I have changed the home folder to my own. If I set it
back to the default: InetPubwwwroot and copy the .asp
file into hat folder, then I don't get the problem.
I have chacked all possible access restrictions and even
propagated the InetPubwwwroot security parameters to my
own home "root" folder. Non .asp files works fine.
