Hi bigdog,
>From the error, it appears that you have configured IIS to execute files in
that directory. The request is failing because the lockdown feature in IIS
6 is refusing to run the esinst.exe as a CGI on the server. This is
probably a good thing.
I can tell this because the status information is "404 2". This means the
response was a 404 with suberror 2. 404 with suberror zero is a "real" 404
response (ie. the file was not found). 404 with suberror 2 means that
lockdown did not allow the executable, dll or script to run. Finally,
there is a 404 with suberror 3 that indicates that IIS tried to download the
file to the client, but could not determine a MIME type (If this had been a
404.3, then adding .exe as a MIME type would have corrected it. As it is,
.exe files have the MIME type of application/octet-stream by default, so you
generally would not need to add it).
To allow esinst.exe to be downloaded as a file to the client, be sure that
the virtual directory that contains is does not have execute permissions in
the IIS's MMC. If you really wanted to run esinst.exe as a CGI on the
server, then you would need to go to the "Web Service Extensions" folder in
IIS's MMC, add it as a new extension, and then allow it to run.
One final note: We added the suberror status to the log files, I believe,
between RC1 and RC2. If you are running something prior to RC2, then it's
possible that "404 2" means that the error was a 404 with a Win32 error code
2. In this case, it's a "real" 404 and it just wasn't found. You should be
able to tell conclusively if this is the case by looking at the fields in
the beginning of the log file. It the field after the HTTP status code is
the suberror, then everything above applies. If the field after the HTTP
status code is the Win32 error (or anything other than suberror), then it's
probably a real 404.
I hope this helps,
