sorry, but you didnot understand my point , I didnot call the address directly I used call LoadLibraryA, and patched through ollydbg, I understand where the kernel base is,but my point is that calling LoadLibraryA should be resolved by w2k, and it didn't.(thanks for your clarification).

i see

the thing is, if you patch directly in olly 'call LoadLibraryA' it then codes a direct call to that api. i mean it IS a direct call here is the raw bytes for the two calls:

Quote:
00476FDC: E88069A077 call 077A40161
00476FE6: E84743A077 call 077A3DB32
it uses 'E8' which is a direct call. this is an honest oversight and nothing to argue about, cuz it is what it is... a direct call. this is why i fixed it to an indirect call 'FF15' and the address pointer to the appropriate api.

sorry mate

I see it now, ollydbg resolves LoadLibrary to its address in xp when I save the patch, when you run it on w2k the address sure will be different.so to go around it you went after LoadLibrary through the import.thanks fruitful discussion
