Problem configuring Receiver 4.4 on Windows Embedded with WCM

Good afternoon chaps,

We have some Thin Clients on the bench in the lab for testing. They're Dell\Wyse D90D7's or 5010's, same thing, running Windows Embedded 7 Standard.

We're almost there with regards to configuration. We'd like to have them boot straight past the Embedded OS and load Citrix in appliance mode. Unfortunately i cant seem to get the Account to load properly.

We're using Wyse Configuration Manager v1.5 to create config files that are pushed out from the WDM server. There are options for the type of connection to Citrix; XenApp, XenDesktop, Storefront and Gateway. I have attached a screenshot of the WCM options.

In summary:

Choosing Storefront or Gateway, and entering the FQDN of the SF server or the FQDN of the NS yields the same result. An error comes up stating "Cannot connect to DWCM-Citrix" (DWCM-Citrix is the name the account is given when setup from the config file.

Entering either of the FQDN's manually on Receiver works fine, for both SF and NS.

The end goal is to have users log in to the Windows Embedded device which runs Citrix Receiver in appliance mode, with SSO, so user get passed straight over to their relative sessions.

Is there any other way to set the accounts in Receiver for all users? These Thin Clients have a Write Filter so any changes made will need to be done by the local admin account. So i'm thinking it's likely to be a registry setting of some sort.

Does anyone have any experience with setting up Receiver from WCM?

Any ideas would be greatly appreciated.
