FindFirstFile Returns Error "The Network Name Was Deleted" (145884)

The information in this article applies to:

Microsoft Windows NT Server 4.0
Microsoft Windows NT Workstation 4.0

This article was previously published under Q145884

SYMPTOMS

If you programmatically add a share (NetShareAdd) and directly after this run FindFirstFile on the directory just shared, the following error is returned:

The network name was deleted.

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

CAUSE

The message "Invalid UID or TID" is returned internally because the SMBs SrvSmbSessionSetupAndX and SrvSmbTreeConnectAndX haven't occurred yet.

WORKAROUND

After doing the NetShareAdd, call FindFirstFile more than once. After the first call, the error is not returned.

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!"));}

STATUS

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