Hi,

I have 2 similar apps, that utilize COM+ component services. Application
server that is running COM+ is Windows 2000 with SP3. Users were running
applications on the machines with Windows 2000 SP3 as well. We're trying to
get users to switch to XP with SP2 installed. One of the applications runs
fine, but another one gives me problem:
----------------------------------------------------------------------------------
An unhandled exception of type 'System.UnauthorizedAccessException' occurred
in mscorlib.dll
Additional information: Access is denied.

at System.Runtime.InteropServices.Marshal.ThrowExceptionForHR(Int32
errorCode, IntPtr errorInfo)

pa, Type serverType)

System.Runtime.Remoting.Activation.ActivationServices.IsCurrentContextOK(Type
serverType, Object[] props)

Now, nothing was changed, I installed the same proxies that were installed
on the previous machines. I tried to create a new proxy, but that didn't
help as well. Please advise. No authorization was changed, I even tried to
add an account, that COM+ is running under to Admin group, but that didn't
help as well. Is there anything with XP SP2 that I need to be aware of
pertaining to COM+?? How come on of the apps is running fine and other is
failing? Thanks a lot in advance, any help is appreciated.

I'm sorry, I forgot to mention that both apps were developed on.Net
Framework 1.0/C#.
Thanks,
