I'm trying to debug a windows service that I created.  When I go to debug->Attach to Process and selected the service I get the error "Unable to attach to the process.  The requested operation is not supported."

 When I try to run the service under my account (Which is administrator) and try to attach to the process I get "Unable to attach to the process.  You do not have permission to debug the process"

 When I try the first way in VS2008 I get "Unable to attach to the process.  You do not have permission to debug the process".

 My co-worker can run my service on his machine and attach to the process.   His process type is x86, Managed.  Mine is set to just x86.  I have a newly imaged machine at my work.

 
Does anyone know how to fix this?  I'm a new .NET developer to this department and I can't get anything done until this gets fixed.

 Thanks for your help,

Nate


 

Is your service written in C++ or C#?

 VB.NET

You should be attaching as Managed then. x86 means native code like C++.

Attach Tol Process.. -> Click on Select... button and pick the mode.

 Now I get the error "Unable to attach to the process.  Access is denied"

The "Type" is still x86. 

 thanks for your help btw, I really appreciate it.

When you click on Select..., are you able to unselect x86 and check "Managed" instead? As for access - are you running as admin? You may have to be full admin to be able to debug services.

 Here's what I see.

A few odd things there. First, process is displayed as x86 - is it really managed code process? Second, I see that you are able to check 'Managed' and uncheck 'x86' - did you try it? Third, access may be denied if process is running under impersonation or another user. Even admin does not have access to another user data.
