On my PC (Win 2000, VFP6 SP5) SYS(2600) still returns empty string.
Instead of

lcBuffer = SYS(2600, Long2Num(lcBufPtr), 32)

if I use

lcBuffer = GetStrFromMem( lcBufPtr )

it works.
This works for a local user. I still have to make it work for Domain User in which case NetUserGetInfo returns error 2221 which means Username not found.
I guess I'll have to use IADS for it.
Thanx a lot. Your help is widely appreciated.
