DFSUtil Examples

This example dumps the DFS configuration of the local computer for the fault-tolerant root "dfsft" in the a.com domain. Multiple servers back up the root and \apps shares (child nodes) in the \\a.com\dfsft DFS tree.

Type the following at the command prompt:

C:\UTILS>dfsutil /VIEW:\\NA-DC-01\dfsft

Output similar to the following displays:

Getting DomDfs metadata for DFSFT

To display the information contained within the SPC table, type the following at the command prompt:

C:\UTILS>DFSUTIL /SPCINFO

Output similar to the following displays:

NtStatus=0x0, status=0x0

To show the client cache of the DFS namespace, type the following at the command prompt:

C:\UTILS>dfsutil /pktinfo

Output similar to the following displays:

--mup.sys--
3 entries...

ShortEntry: \distfolders\release

DFSUTIL completed successfully.

The example below:

1. Displays the existing Partition Knowledge Table (PKT) for \\Distfolders\Release\Namer\Bnum\Vers by using the /pktinfo parameter.
2. Flushes all client PKTs by using DFSFLUSHPKT ("EntryPath=[*]").
3. Shows the empty PKT on the client by using the /pktinfo parameter.

To display the existing PKT, type the following at the command prompt:

C:\UTILS>dfsutil /pktinfo

Output similar the following displays:

--mup.sys--
NtStatus=0x0, status=0x0
2 entries...
Entry: \distfolders\release
ShortEntry: \distfolders\release
   0:[\DISTFOLDERS\release][0x1]
 
Entry: \distfolders\release\namer\bnum\vers
ShortEntry: \distfolders\release\namer\bnum\vers

   2:[\servxx3\namer.bnum.vers][0x0]
   3:[\servxx4\namer.bnum.vers][0x0]
   4:[\servxx2\namer.bnum.vers][0x0]

Now to flush the PKT cache, type the following at the command prompt:

C:\UTILS>dfsutil /pktflush

Output similar the following displays:

EntryPath=[*]

To redisplay the existing PKT, type the following at the command prompt:

C:\UTILS>dfsutil /pktinfo

Output similar the following displays:

--mup.sys--
NtStatus=0x0, status=0x0
0 entries...
