Sharing violationin fopen function with "w" flag

Hi,

I have a a application developed in Visual C++ 6.0. It is running very well
in Windows 2000 platform but in XP I have got some random problems. I have
been testing and I have seen, I think, that the problem is in fopen function.

I am running VMWare machine with XP Pro Service Pack 2. The VMWare is
running on Windows 2000. The files are in Windows 2000 and I read the filed
trought the net.

If I run the same application in Windows 2000 there is not problem. It run OK.

The problem is follow: When I call the fopen function in a exact pont,
sometimes the system going to down and slowly and when the system return the
file hanlde, sometimes return OK and sometimes return 0x00000. I have use the
"filemon" tool and, in this situation, the filemon shows: "Sharing violation
error"

Also, I have compared the systems calls with filemon in W2k and XP and I hav
seen that the fopen funtion, in W2k, make a "Query" call but in XP not.

I have spent very time in order to discover the problem but I have not seen
the solution.

Also I have installed several hotfixes after the SP2.

Thanks.

Go prod System Internals website and download proc monitor, see if anything
else has that file open... an antivirus, for example.
