Connection to the deployment share could not be made (DFS share, works fine on site A, not on Site B)

Question

I'm trying to isolate this problem with MDT..., unable to find a solution matching this error.
We have two sites, with a DFS replica between the servers, which works fine. 
Server A: Windows 2012 R2 standard
Windows Automated Installation Kit for Windows 7 
MDT 2012, Update 1 
WDS configured for PXE boot 
Distributed File Share
Server B: Windows 2008 R2 Standard 
MDT 2012, Update 1 
WDS configured for PXE boot 
Distributed File Share
The local path on both servers is on E:\DFS-Deploymentshare
The DFS path is \\domain.com\it\deploymentshare
When deploying on Site A, the deployment run smooth without problems.
When deploying on Site B, the deployment fails to create connection to the share. 
A connection to the deployment share (\\domain.com\it\deploymentshare) could not be made.
Connection OK. Possible cause: invalid credentials.
Pressing F8, to reach a command prompt. "ipconfig" shows an IP-address. I can PING the deployment server. I can mount the Deployment share using "net use" and providing the username/password added in the bootstrap.ini and "retry"
in the message box and the deployment continues.
In the BDD log i get this timeout:
<![LOG[Unable to connect to \\domain.com\it\deplomentshare. Sleeping for 5 seconds. 
<![LOG[<Message containinng password has been suppressed>
<![LOG[Access is denied.
However everything is the same both in site A and B so this seems very strange!
The complete system has worked this way before.
Bootstrap.ini contains: 
DeployRoot=\\domain.com\it\deploymentshare 
UserDomain="domain" 
UserID="mdt-account" 
UserPassword="password" 
I've been trying all I can think of, but Im still faced with this error and to keep in mind the same share working on another site.

Ok, so by the sounds of it, there is something wrong with the share permissions (especially if your account works fine but the MDTserviceaccount does not work even when part of Domain Admins).
So you need to do the following:
Start in Site A:
Boot into WinPE on a workstation in site A
Ping server-a
Ping server-b
Run "net use * \\server-a\deploymentshare$ /user:DOMAIN\MDTserviceaccount"
Type in the password for MDTserviceaccount when prompted
Browse to the newly mapped drive and list the files/folders
Make sure you can see the relevant MDT folders, like Applications, Out-of-Box Drivers, etc
If all that works, then you can move to site B
Start in Site B:
Boot into WinPE on a workstation in site B
Ping server-a
Ping server-b
Run "net use * \\server-b\deploymentshare$ /user:DOMAIN\MDTserviceaccount"
Type in the password for MDTserviceaccount when prompted
Browse to the newly mapped drive and list the files/folders
Make sure you can see the relevant MDT folders, like Applications, Out-of-Box Drivers, etc
By going through all of the above, you should be able to see where the problem lies.
If all of the above works with no problems, then you have the details incorrectly specified in the BootStrap.ini (or possibly CustomSettings.ini). Confirm that you have the following specified in the relevant ini file:
DeployRoot
UserID
UserDomain
UserPassword
You can have a look in the help file if you need to confirm that these properties are configured correctly. Look under
Toolkit Reference - Properties - Property Definition in the help file.
Both Site A and Site B is successfully
I have changed the Password of deployuser to test if it is correct. and i have copy/pasted the password into the DC when changing the password.
I have tested the password by logging on to a client-pc with the deployuser as username and the temp password "Pa$$w0rd" successfully.
Both UserID, UserDomain and UserPassword is entered after the help file for Property Definition.
Please see the Bootstrap.ini and Customsettings.ini (NB! Servernames, Domainname and Passwords are fictive.)
