windows2000 problem

[chrivo]

hi

it is not a problem from cvi but a problem from win2000!
if someone can help me or give me some hints i would be very happy!!!

We use a device with MS-DOS +ADDON to run a fileserver on this device!
Now i want to open a file on this device with
fopen(\\server\c\str.txt,"w");
but on the win 2000 system the fopen function returns a Null-Pointer
with the errorno EIO (Generall I/O Error)!
fopen(\\server\c\str.txt,"r"); works fine!!!!!

if i will make a Directorymapping to this device (f:\==>\\server\c)
then also the fopen(f:\str.txt,"w"); works fine!!!

Can anyone give me some hints!!
thanks a lot
chris
