On my machine I have these DLLs in the System32 and in the I386 folders but
on the not working machines there is no I386 folder.

However, the username can be the case as well. On the not working machine
the username exists but it's a group username without actual full name.

Thanks everybody. I'll research it further.

Also, "netapi32.dll" may not exist or it may not be available. I'm not sure
if it has to be registered or just in a specific folder or any folder within
the path statement. Start by making sure it is in the same folder as the
other computers

(Mine is in C:\Windows\System32)

The code only works on 32 bit machines. Ok, there are not many 16 bit
machines left and I don't know of any 64 bit, but still, it is a nit pick
that had to be plucked.

There will be no user name if there is no such environment variable.
Check
in a DOS Command prompt by typing "Set Username". If the message says it
is
not defined then it needs to be created. Of course, this is an
opportunity
to fix the code so that it works when the Username variable doesn't exist.

The code with API functions below is working perfectly almost on all
computers but on a few ones is not working. It's from the code to get a
full
user name.
What could be the cause of this?
Thanks
