无法从使用c＃（Windows 2003服务器）编写的Windows服务访问DCOM对象，但可以在作为控制台应用程序托管时访问该对象

Question

I have written an application in C# that writes to an accounting system via a DCOM object (name of the object is Toolkit Object). When this application is hosted as Windows Service in Windows 2003 the service is unable to open the DCOM object although the user identity under which the service is running has all the necessary access rights.

When I host the same application using a console app it works fine.

I have tried tweaking the access rights to the DCOM object through DCOMCNFG but nothing seems to work.

Answer 1

COM uses Windows Messages to communicate between processes. So the first question is: Does your service have a message pump? If not, that's most likely the problem.

Try creating a hidden window (or a visible window to test the hypothesis).
