When passing Delphi records to windows functions, you have to declare them "packed" so the compiler doesn't realign the fields.
i.e. type myRec=packed record ..... end; Not sure if this applies here, DWORD should be the default alignment, so a record of DWORDs is already packed. But you should give it a try. hth, M.

I just looked at the code and boy, it has a big flaw. I'm assuming this is where your problem is:
Code:
var Buffer :pointer;
Rek :PTime_Of_Day_Info;
sex:dword;
begin
sex:=NetRemoteTOD(nil,buffer);
if sex = 0 then
Rek:=PTime_Of_Day_Info(Buffer);
writeln(rek.tod_elapsedt);
writeln(rek.tod_msecs);
writeln(rek.tod_hours);
.... lots of other fields
Note the stuff in bold. If the call to NetRemoteToD succeeds, then it executes that line. If not, it doesn't execute that line, so Rek could be pointing anywhere. Regardless of whether the function succeeds or fails, it is writing out data. So, if NetRemoteToD fails, rek is pointing to uninitialized data and hence the data that is written out is completely bogus.
