GetProcAddress(hDLL,"Start_server") failed

[uwei]

Hi,

we've some Win2003 Servers which could not start PcHelpware_sc.exe.
Before installing of some software and win2003 SP2 and Netframework 3.0 everything works fine.
We've also servers with the same installation (SP2, NF3.0 ...) which could start PcHelpware_sc.exe.


I tested the following (C++/VS2005):
HMODULE hDLL = LoadLibrary ("1SCDLL.dll");
Start_server_fn pStart_server;
MessageBox(NULL,"ProcAdr","",0);
if (hDLL != NULL)
{
pStart_server = (Start_server_fn) GetProcAddress(hDLL,"Start_server");
if (!pStart_server)
{
// handle the error
FreeLibrary(hDLL);
return 0;
}
else
{
// call the function
MessageBox(NULL,"Start","",0);
}
.....
"ProcAdr" is displayed "Start" is never displayed.
LoadLibary succeeded, GetProcAddress failed?
I rename to 2SCDLL.dll and load 2SCDLL.dll to ensure there is no other version of 1SCDLL.dll anywhere - but the same error.
I try it with C# and get the error: "1SCDLL.dll: "Unzulaessiger Zugriff auf einen Speicherbereich" (invalid access on a memorypage).
I checked invalid dependencies with depends.exe of the 3 dlls - all seems to be fine.

All the tests succeeded on the other servers.


I'dont understand - could anyone help?

Hi,

had found the following Topic: "Windows 2003 Server R2 will not extract or run pchelpware" and could resolve the problem(DEP).

Thx
