FindFirstFile Returns Error: The Network Name Was Deleted

ID: Q140062

The information in this article applies to:

Microsoft Windows NT Workstation version 4.0
Microsoft Windows NT Server version 4.0

SYMPTOMS

If you programmatically add a share (NetShareAdd) and immediately run FindFirstFile on the directory just shared, the following error is displayed:

The network name was deleted.

This only happens if the share is created on the local computer.

CAUSE

"Invalid UID or TID" is returned internally because there is no SrvSmbSessionSetupAndX and SrvSmbTreeConnectAndX Server Message Block (SMB) yet.

RESOLUTION

After NetShareAdd, call FindFirstFile more than once. Only the first call returns the error.

STATUS

Microsoft has confirmed this to be a problem in Windows NT version 4.0. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

With the correct SHARE_INFO_502 structure, the following code would cause this error:


ret = NetShareAdd(TEXT("\\\\SERVER"),502, (LPBYTE)&si_502,NULL);

   if ( ret != 0)
   {
      wprintf(TEXT("NetShareAdd() error!"));
      return;
   }

   if((fh=FindFirstFile(TEXT("\\\\SERVER\\TEST\\*"),&wfd))==
   INVALID_HANDLE_VALUE){
      ErrorHandler(TEXT("FindFirstFile() failed!"));}
