Assembly load problem in Winlogon, Windows 2000 ..


Hello All..

We are attempting to load a .Net assembly DLL from
a GINA (Winlogon) DLL. This is a C# DLL, signed
and GAC'ed.

In Windows XP, this works fine. In Windows 2000
however, we get this exception:

System.IO.FileL oadException: The given assembly name or codebase, 'MyDLL', wa
s invalid.
File name: "MyDLL"
at System.Reflecti on.Assembly.nLo ad(AssemblyName fileName, String
codeBase, B
oolean isStringized, Evidence assemblySecurit y, Boolean throwOnFileNotF ound,
Ass
embly locationHint, StackCrawlMark& stackMark)
at System.Reflecti on.Assembly.Int ernalLoad(Assem blyName assemblyRef,
Boolean
stringized, Evidence assemblySecurit y, StackCrawlMark& stackMark)
at System.Reflecti on.Assembly.Int ernalLoad(Strin g assemblyString,
Evidence as
semblySecurity, StackCrawlMark& stackMark)
at System.AppDomai n.Load(String assemblyString)
....

We have determined (I think) that this does _not_ mean
the DLL was not found.. there seems to be something
else about the assembly/DLL that bothers the loader.

Once the user is logged on to Win2K, this DLL works
fine.. it is the Winlogon invocation that fails.

Has anybody run into this sort of problem ?

Thank you..

Cris..

I have a ASP.Net web application that has two assemblies that run under com+. Under Windows 2000 the two assemblies are added to com+ automatically when instantiated from the web site. For this to happen we had to change the context in which asp.net runs from machine to SYSTEM by modifying the machine.config file. Under Windows 2003 no matter how asp.net is set to run as either machine or system. I get the following error: ...

My problem: I load an some assemblies (strong named) from a byte array using Assembly.Load(byte). They load fine. But one one of them is actually accessed, it's referenced assemblies can't be found on disk and I get a TargetInvocationExeption. For example, let's say I have a C# win forms application called Prog. Prog.exe uses Assembly.Load(byte) to load two C# class library assemblies,

Hello, I am trying to use vs.net 2005 to migrate a project originally in vs.net 2003. I started with creation of a "web site", and then created folders for each component of the site. I read somewhere that each folder under the "web site" is compiled in separate assembly. I however, did not find that the "web site" creation in vs.net 2005 created any AssemblyInfo.cs file.

I have a web service running impersonation of a domain account on Windows Server 2003. I need to access a share which the Web Service classes, themselves, appear to be able to create and access.

This installation works fine on Windows 2000 and Windows XP Professional. However,...

I have a .NET 2.0 application divided in two assemblies; the exe and a dll. The application generates a plugin-dll which is then loaded in a separate AppDomain (along with a second instance of my application dll). It's been working for months and now the it's not working from my application exe anymore but still working from NUnit when testing the dll. What could have changed in my exe? Some configuration thing in my VS2005 project?

I have a solution consisting of a c# project as win application and a c++ project as classlibrary. Both are .net 2.0 The classlibrary handles some loading of quicktime movies, but that should not be relevant. On my development machine I build the exe and dll and run the exe which has a reference to the dll. At some point it uses featured in the dll. This works fine. Then I copy my exe and dll to the target system and when the featured...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
