Output Description for /PktInfo

Current Partition Knowledge Table (PKT) information can be displayed by using the /pktinfo parameter. The following describes the type of output produced when /pktinfo is used. The description numbers correspond to the numbers in the sample output.

1.  The initial entry specifies how many entries are included in the output.

2.  Every entry has both a full (Entry) and a short (ShortEntry) name.

3.  Expires or Time To Live (TTL) is the length of time a DFS client stores referral information from the PKT in its local cache. The DFS client requests new information from the PKT if the TTL expires or the client is restarted. The TTL is reset if the shared folder is accessed before it expires.

4.  UseCount is the number of times it's used since got this referral. Type specifies the type of referral being made.

5.  Each entry contains a sequentially numbered target list. A referral is a list of targets a DFS client receives from the PKT when a user attempts to access a root or a link in the namespace. Referrals are cached locally on the client for a time specified by time indicated in Expires. The referral information can tell you which target is active for your DFS client. The number after each target name indicates the state of the target. Attempts to access an inactive target will be referred to the currently active target.

  • State 0x21:inactive or not responding

  • State 0x31:responding and an active target

6.  An ACTIVE target status indicates it is currently being accessed by the client. If access to this target fails, the client will try to access the next target in the list. In this entry, the client would try to access the 12th target, \dom-dc-12.dom.company.com\SysVol.
