Hello,

I've seen your post on a couple of news groups.  I too
was having trouble finding .net framework 2.0.40903.
Everything thing I tried pointed me to the same file;
dotnetfx.exe

I kept trying as I really wanted to play with SQL
Server 2005 express.  I finally noticed that a couple
of the dotnetfx.exe's that I downloaded, were not the
same file...different sizes.

Here's a direct link to the .net 2.0.40903 that I
found:
http://download.microsoft.com/download/9/A/4/9A47D72B-9D98-46CC-87F3-B92E97888E4
B/dotnetfx.exe

PS:  I had to use add/remove programs to first
uninstall .net 2.0 beta as it kept telling me it was
already install.  I also renamed the .net 2.0
directory under c:\winnt\microsoft.net\v2.0.40607 just
be on the safe side...took long enough to find the
this version of .net

Give it a try....Hope it works for you too.!!
