Question

Using wuapi.dll, i am trying to create a update session of the remote server from my local machine. 

Code:

string theServer="TEST-WIN16-202";
string myString1 ="Microsoft.Update.Session"; 
           
Type myType1 =Type.GetTypeFromProgID(myString1,theServer,true);

UpdateSession updateSession = (UpdateSession)Activator.CreateInstance(myType1);

Anyone please help me understand why this error comes and why cannot i create update session.

The error is an access denied. You're trying to access the COM information on a remote machine and you don't have permissions. For this to work you'd have to be running in the context of a user with permissions on the remote machine. That would pretty much mandate a domain account that works on both machines and possibly elevated privileges.

I've never had to use remote COM objects in C# so I don't know what else you'll need to do. I did search a little and people are recommending using WUAPIInterop instead. Or using WSUS. In both cases they tend to use impersonation to get into the right context. Take a look at one example here.
