New Patch Available For DPM

January 29th, 2006 by Joseph Bittman MCSD .Net

    Hot off the press! New patch correcting Short File Name collusion and access denied errors in DPM! The KB article isn’t live quite yet, but you can get the patch by calling in FREE to Product Support Services and asking for the patch related to QFE 911169.

 What the symptoms look like:

#1 Access Denied Error in DPM UI

#2 For the more beefy details, I’ll leave it to my trusted friend, Karan, from DPM: 🙂

“The problem occurs because during a consistency check, both the long name
and the short name of each file must match. Short names are assigned
according to the order in which they are created. Therefore, the short names
of the files on the destination server may not match the short names of the
files on the source server. For example, this problem occurs in the
following scenario: . The LongFileName02.txt file is created on the source
server. The short name of the LongFileName02.txt file is LongFi~1.txt.
      . The LongFileName01.txt file is created on the source server. The
short name of the LongFileName01.txt file is LongFi~2.txt.
      . A consistency check is run. The files are validated by using the
long name in alphabetical order. The LongFileName01.txt file is validated
first.
      . A LongFileName01.txt file is created on the replica. This file is
given the LongFi~1.txt short name.
      . During the next synchronization, the LongFileName02.txt file is
created. The short name of this file is LongFi~2.txt.
In this scenario, the short names of LongFileName02.txt and
LongFileName01.txt are exchanged.

The next time that you run a consistency check, the synchronization fails
because the long name and the short name of each file do not match.
Therefore, the replica remains inconsistent with the source server.

I would recommend installing this hotfix on all DPM servers in production
where you are seeing this problem.”

Now to go call to get it myself!
