NetDfsSetInfo function (lmdfs.h)
Sets or modifies information about a specific Distributed File System (DFS) root, root target, link, or link target.
Syntax
NET_API_STATUS NET_API_FUNCTION NetDfsSetInfo(
[in] LPWSTR DfsEntryPath,
[in, optional] LPWSTR ServerName,
[in, optional] LPWSTR ShareName,
[in] DWORD Level,
[in] LPBYTE Buffer
);
Parameters
[in] DfsEntryPath
Pointer to a string that specifies the Universal Naming Convention (UNC) path of a DFS root or link.
For a link, the string can be in one of two forms. The first form is as follows:
\\ServerName\DfsName\link_path
where ServerName is the name of the root target server that hosts the stand-alone DFS namespace; DfsName is the name of the DFS namespace; and link_path is a DFS link.
The second form is as follows:
\\DomainName\DomDfsname\link_path
where DomainName is the name of the domain that hosts the domain-based DFS namespace; DomDfsname is the name of the DFS namespace; and link_path is a DFS link.
For a root, the string can be in one of two forms:
\\ServerName\DfsName
or
\\DomainName\DomDfsname
where the values of the names are the same as those described previously.
[in, optional] ServerName
Pointer to a string that specifies the DFS link target server name. This parameter is optional. For more information, see the Remarks section.
[in, optional] ShareName
Pointer to a string that specifies the DFS link target share name. This may also be a share name with a path relative to the share. For example, "share1\mydir1\mydir2". This parameter is optional. For more information, see the Remarks section.
[in] Level
Specifies the information level of the data. This parameter can be one of the following values.
100
Set the comment associated with the DFS root or link specified in the DfsEntryPath parameter. The Buffer parameter points to a DFS_INFO_100 structure.
101
Set the storage state associated with the DFS root or link specified in the DfsEntryPath parameter. The Buffer parameter points to a DFS_INFO_101 structure.
102
Set the time-out value associated with the DFS root or link specified in the DfsEntryPath parameter. The Buffer parameter points to a DFS_INFO_102 structure.
103
Set the property flags for the DFS root or link specified in the DfsEntryPath parameter. The Buffer parameter points to a DFS_INFO_103 structure.
104
Set the target priority rank and class for the root target or link target specified in the DfsEntryPath parameter. The Buffer parameter points to a DFS_INFO_104 structure.
105
Set the comment, state, and time-out information, as well as property flags, for the DFS root or link specified in the DfsEntryPath parameter. The Buffer parameter points to a DFS_INFO_105 structure.
106
Set the target state and priority for the root target or link target specified in the DfsEntryPath parameter. This information cannot be set for a DFS namespace root or link, only for a root target or link target. The Buffer parameter points to a DFS_INFO_106 structure.
107
Set the comment, state, time-out information, and property flags for the DFS root or link specified in the DfsEntryPath parameter. For DFS links, you can also set the security descriptor for the link's reparse point. The Buffer parameter points to a DFS_INFO_107 structure.
150
Set the security descriptor for a DFS link's reparse point. The Buffer parameter points to a DFS_INFO_150 structure.
[in] Buffer
Pointer to a buffer that specifies the data. The format of this data depends on the value of the Level parameter. For more information, see Network Management Function Buffers.
Return value
If the function succeeds, the return value is NERR_Success.
If the function fails, the return value is a system error code. For a list of error codes, see System Error Codes.
Remarks
The caller must have Administrator privilege on the DFS server. For more information about calling functions that require administrator privileges, see Running with Special Privileges.
If you specify both the ServerName and ShareName parameters, the NetDfsSetInfo function sets or modifies information specific to that root target or link target. If the parameters are NULL, the function sets or modifies information that is specific to the DFS namespace root or the DFS link instead of a specific DFS root target or link target.
Because only one comment and one time-out can be set for a DFS root or link, the ServerName and ShareName parameters are ignored for information levels 100 and 102. These parameters are required for level 101.
For information level 101, the DFS_VOLUME_STATE_RESYNCHRONIZE and DFS_VOLUME_STATE_STANDBY state values can be set as follows for a specific domain-based DFS root when there is more than one DFS root target for the DFS namespace:
The DfsEntryPath parameter specifies the domain-based DFS namespace, and the ServerName and ShareName parameters taken together specify the DFS root target on which the set-information operation is to be performed.
Examples
The following code sample demonstrates how to associate a comment with a DFS link using a call to the NetDfsSetInfo function. The sample specifies information level 100 (DFS_INFO_100).
#include <windows.h>
#include <lm.h>
#include <lmdfs.h>
#include <stdio.h>
#pragma comment(lib, "Netapi32.lib")
void wmain(int argc, wchar_t *argv[])
{
DFS_INFO_100 dfsData;
DWORD res;
//
// Check command line arguments.
//
if (argc<2)
wprintf(L"Syntax: %s DfsEntryPath [\"Comment\"]\n", argv[0]);
else
{
//
// Fill in DFS_INFO_100 structure member.
//
dfsData.Comment = argc < 3 ? NULL : argv[2];
//
// Call the NetDfsSetInfo function, specifying level 100.
//
res = NetDfsSetInfo(argv[1], NULL, NULL, 100, (LPBYTE) &dfsData);
//
// Display the result of the call.
//
if(res == 0)
printf("Comment set.\n");
else
printf("Error: %u", res);
}
return;
}
