Urgent: XP and CreateFile

NTDEV
1

I’ve created a service (running using System account) on XP that calls
CreateFile on a partition like that below:

CreateFile(“\\.\C:”, GENERIC_READ|GENERIC_WRITE, FILE_SHARE|FILE_WRITE,
NULL, OPEN_EXISTING, 0, NULL)

But the call fails with the error “File not found” type.

If I try the call from a Win32 application using the same call also on XP,
the call succeed. Alternatively the call made from the service on NT/2K
also works. Strange.

Anyone has any idea whats wrong or have faced this too?? Thanks.

Maybe “C:” symlink is not assigned for this service under XP.
It has some improvements in DosDevices directory, so, this can be true.
