Hello Everyone,
I implemented a authorization plugin using C# on Windows Server 2008. After
following the steps as in
http://msdn2.microsoft.com/en-us/library/ms753902(VS.85).aspx, I got the new
plugin shown in the server (BTW, I didn't forget to use ComVisible(true)" in
AssemblyInfo.cs before I built the plugin). But when I tried to enable the
plugin from the server, I got error "0x8007005, access is denied".

I didn't work on the server directly, but using the remote desktop to
connect with the server.

I checked the security of the dll, say MyPlugin.dll, under
C:\Windows\System32\wincdows media\server, it has read & execute permissions
for System, NETWORK SERVICE, Administrators, Users. I added Administrator
but still got the error.

Any idea about how to fix it?

The other question is that I cannot delete MyPlugin.dll from
C:\Windows\System32\wincdows media\server. It says that it's open in another
program. I couldn't think of where the dll was referenced (I have run regasm
MyPlugin.dll). Any idea about this?

Thanks a lot!

Helen

Problems solved! It turns out that the program doesn't have the write
permission to the log file.

About the second question, I could delete the MyPlugin.dll after I stopped
the server.
