Re: ClickOnce installation fails (very interesting log from IIS)

I have experienced some scenarios that cause trouble:
* Their firewall blocks access to .exe/.dll-files
* Their local proxy/firewall caches everything, so the .exe your
application sees is not the latest version
* Their firewall blocks HTTP Resume download-commands (not sure if
ClickOnce uses http resume, but the BITS downloader does)

In a high security environment I would guess the first one is the problem.

I've made some very very interesting findings in the server (IIS) log. For
one of the clients that fails, ClickOnce seems to ask for a file that does
not exist! Strange indeed, since it's the exact same installation on all
clients. I wonder what makes it do this. I paste the interesting bit of the
logfile at the end of this post.

To begin with, the client asks for setup.exe, TheApplication.application,
TheApplication.exe.manifest, TheApplication.exe.deploy. The server gives the
files to the client (response 200) no problems. Then all of a sudden, it
starts to ask for non existing files, like TheApplication.exe.deploy.config,
and all possible combinations of DataAccess.DLL. The really interesting part
is that the server has this file
(TheApplication_5_0_0_2/DataAccess.DLL.delpoy), with the .deploy file
suffix, but none of all the combinations that ClickOnce requests. In short,
it asks for pretty much all combinations of DataAccess except the one that
really exists. The clients where everything works (on another network), it
immediately asks for, and gets, the correct files.

Does anyone have a clue?
