I could use some guidance in interpreting the output of dfsutil /pktinfo.

Using the following example:

PS C:\Users\kbrandt> dfsutil.exe /pktinfo
...

Entry: \long.biz.foo\Images
ShortEntry: \long.biz.foo\Images
Expires in 4 seconds
UseCount: 1 Type:0x81 ( REFERRAL_SVC DFS )
   0:[\OR-UTIL01\Images] ( TARGETSET )
   1:[\NY-FS01\Images] AccessStatus: 0xc00000be ( TARGETSET )
   2:[\NY-UTIL01\Images] AccessStatus: 0 ( ACTIVE )

Entry: \NY-UTIL01\Images
ShortEntry: \NY-UTIL01\Images
Expires in 65 seconds
UseCount: 0 Type:0x81 ( REFERRAL_SVC DFS )
   0:[\or-util01\Images] ( TARGETSET )
   1:[\NY-FS01\Images] AccessStatus: 0xc00000be ( TARGETSET )
   2:[\NY-UTIL01\Images] AccessStatus: 0 ( ACTIVE )

Entry: \or-util01\Images
ShortEntry: \or-util01\Images
Expires in 0 seconds
UseCount: 0 Type:0x81 ( REFERRAL_SVC DFS )
   0:[\OR-UTIL01\Images] AccessStatus: 0 ( ACTIVE TARGETSET )
   1:[\NY-UTIL01\Images] ( TARGETSET )
   2:[\NY-FS01\Images]

Entry: \FOO\Images
ShortEntry: \FOO\Images
Expires in 108 seconds
UseCount: 0 Type:0x81 ( REFERRAL_SVC DFS )
   0:[\OR-UTIL01\Images] AccessStatus: 0 ( ACTIVE TARGETSET )
   1:[\NY-UTIL01\Images] ( TARGETSET )
   2:[\NY-FS01\Images]

What do the three states TARGETSET, ACTIVE TARGETSET, and ACTIVE mean exactly?

In particular, why might OR-UTIL01 be ACTIVE for \long.biz.foo\Images but the shortname version FOO\Images have NY-UTIL01 as ACTIVE TARGETSET? I'd like to have a better understanding of this to know if it is normal or not. Once I understand it, I might be looking at and issue with IPv6 being disabled (http://support.microsoft.com/kb/2003961) if this isn't normal.
