 |

Hi Madshi,
I am doing injection of a couple system service (RPC and DCOMLaunch) using the InjectLibraryW. In most cases it works ok, but sometimes it returns FALSE, GetLastError returns error 0x7A. Injection is performed by helper service that works under the NT AUTHORITY\SYSTEM account. Process handle that is used for injection is open with PROCESS_ALL_ACCESS.
Can you please help to find out the reason of this failure?
P.S.
I use madCHook v2.x
P.P.S.
In the rare cases DLL is actually injected even if InjectLibraryW returns FALSE, but during uninjection it returns the same error code and DLL is not uninjected. |

That's weird! Are you using the latest 2.x release?
Is there any pattern to when injection succeeds/fails? E.g. is it always the same process where it fails? Or is it seemingly random? Is there an easy way for me to reproduce the problem? |
