Cannot enable a custom plugin in Windows Server 2008

[Guest Helen]

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!

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.
