Peachtree 2010 on windows server 2008 R2

I instoll Peachtree 2010 on windows server 2008 R2 on the server and client computers with windows 7 OS and I can see all the files that I shared and mapped on all the client computers as a folder with there drive (W, Z, T...). But I can't open the existing company account with Peach-tree 2010 on the client computer from the folder that i can open on the server PC. About the network I checked with Ping and net view on all the PC and it is working even more I can see other excel files on all the client PC with no problem. I need help on this thing.
