Why Shadow Copy Isn't Working No More?

[kvarnerexpress 0]

Here is the situation. I turned on shadow copy on my file server and it used to work when the file server is also a DC. Now that it is no longer a DC and only a file server, the shadow copy doesn't seems to work. When I right click on the shared folder on my client workstation and go to properpties, I do not see the previous version tab available anymore. I went to check the add/remove to verify if the previous version client has been uninstalled and it is still there. So why isn't shadow copy work no more after we switch to a new domain. I would think that it shouldn't interrupt the shadow copy procedure but it did. Help is appreciated.
