File Access through a network

We have a remote company in Illinois that needs to access our(HQ) files through the network. Unfortunately we have had limitedsuccess with this because it is extremely slow on their end toaccess the files.

Speaking with IT, we have tried Citrix and Windows Server 2008 andI believe WS2008 worked slightly better than Citrix.

What is everyone else doing for this application?

I am sure this has probably been covered already but any help wouldbe appreciated.
Thanks,
