When using BizTalk to send and receive from a file share is usually pretty simple. However when you combine this with a DFS network file share, it gets a little bit more complex.
We found our receive location was not starting, and simply failing to work.
So we did mange to get this to work here is how:
You firstly need to have the right share, as some users will use \\machinesname1\share$ and others something else.
The correct share to use is the DFS defined share, so when the DFS storage moves the share is maintained, and not lost. Always find out what the main share name is for the DFS network.
Next you need to set the correct network file share permissions on the network folder. When connecting to a network file share using BizTalk File adapter just specifying "Modify" rights is not sufficient. In simple configuration terms, you would need to have a minimum of "Full Control" or the BizTalk Host Service Account.
Some system admins don’t like this, you need to make sure you have the permissions ONLY set on the folder you are actually reading/writing to.
For the FILE Receive Adapter
After you provide "Modify" rights, Click on "Advanced" button and on the Advanced Security Dialog, edit the permission entries for the BizTalk Service Account
Here you will notice that the "Delete Sub Folders and Files" option is not given by default. This is exactly the missing link for the receive adapter.
Simply set this property and you do not need to set "Full Control"
We had to set list access all the way up the file tree for us to even see the folder.
EG: Our share was: \\dfssharename\saa$\Folder1\Folder2\Folder3\Folder4\IN
We needed to set list permissions on Folder1, Folder2, Folder3 and Folder 4
Then full modify/delete rights, with the setting Delete Sub Folders and Files.
Only then did it work.
For the FILE Send Adapter
If you are NOT USING the "use temporary file while writing" attribute on your send port, only the following permissions are required on the permissions entry dialog
o Create Files / Write Data
If you are using the "use temporary file while writing" attribute on your send port, the following permissions are required on the permissions entry dialog
o Create Files / Write Data
o Delete Files
o Delete Sub Folders and Files
o Read Permissions
