Close locked File


Hi All

As cDOT does not currently support the ability to close locked files via the MMC, here is an example workflow of how to automate the process of close a locked file on a CIFS share (EG microsoft access database).

The workflow accepts a single input parameter containing either the DFS or UNC path of a file to be closed in "double quotes"

For example:

DFS = "\\testlab.local\data\qtree01\data\reports\reports.accdb"

UNC = "\\nvaunsw100\qtree01$\data\reports\reports.accdb"

If the file is a DFS path the workflow will export the DFS namespace and enumerate the UNC Path of the enabled DFS target (This requires the DFS managment tools to be installed on your WFA server).

It uses the "dfsutil.exe root export" command to export the DFS namespace to xml which is parse to find the enabled target of the specified DFS link.

The UNC Path is translated to the file mount point and parsed to the "vserver locks break" command.

Here is an example of the workflow logs ensuring the process is auditable.

The workflow requirements are: 

  • The “vsadmin” account enabled on the vserver serving the CIFS share
  • The credentials for the “vsadmin” account are added to the WFA Cache
  • The file input parameter must be in double quotes
  • DFS Management utilities installed on the WFA server
    >Install-WindowsFeatuure RSAT-DFS-Mgmt-Con

NOTE: If WFA is installed on Windows Server 2012 R2 the DFSN powershell module could be integrated to manage the DFS namespace instead of "dfsutil.exe"

Hope that helps

Cheers Matt
