Error 977 from LookupPrivilegeValue

Hi
I'm trying to set a privilege value, but LookupPrivilegeValue returns error code 997, from GetLastError() Code:

Code:

DWORD eh = GetLastError();
SetLastError(0);
HANDLE tokenHandle;
TOKEN_PRIVILEGES tp;
LUID luid;

if (GetVersion() >= 0)
	{
		if (!OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &tokenHandle))
		{
			eh = GetLastError();
			MessageBox(NULL, "Error opening process token", "Error", MB_OK);
			return false;
		}
		eh = GetLastError();
		if (!LookupPrivilegeValue(NULL, "SeDebugPrivilege", &luid))
		{
			eh = GetLastError();
			MessageBox(NULL, "Error looking up privilege", "Error", MB_OK);
			return false;
		}
		tp.Privileges->Luid = luid;
		eh = GetLastError();	
		tp.PrivilegeCount = 1;
		tp.Privileges->Attributes = SE_PRIVILEGE_ENABLED;
		if (!AdjustTokenPrivileges(tokenHandle, false, &tp, 0, 0, 0))
		{
			eh = GetLastError();
			MessageBox(NULL, "Error adjusting token", "Error", MB_OK);
		}
	}

Does anyone knows whats wrong here?

Thanks in advance

Error 977 Is not documented, confusing

How embarrasing, I ment 997 :-S. It kinda works now, I get access to the process but I think that it still returns 997.

Thanks for the reply

Where does the error occur now? Still LookupPrivilegeValue?

Yes, but now I'm able to use OpenProcess with all access, so that part works.

You can't call GetLastError in the middle of nowhere and expect a useful result. A recent post:

• The return value of the function indicates it has failed.
• The function is documented to provide a GetLastError value.

At other times, the GetLastError value is not useful.

okay, I see thanks
