No file sharing with WPA-PSK TKIP

Hello,

I have an infrastructure home network with two desktop (wired) and two
laptop (wireless) computers. When using WPA-PSK AES encryption, any
computer can share files with any other computer, as well as access the
internet, ping any other network computer, etc. All computers are operating
with Windows XP Pro

I have added a wireless print server, which only supports WPA-PSK TKIP; so
in order to make it work, I have changed my encryption level to WPA-PSK
TKIP on both laptops and the wireless router (Belkin F5d7230-4). After
doing this my two laptop computer cannot share files with each other or the
desktops ("*folder* not accessible", "might not have permission", "network
path was not found"); however, they can successfully ping each other,
connect to the internet. If I change encryption back to WPA-PSK AES, I am
able to share files again.

I have searched Belkin and MS Windows websites, newsgroups, and google with
no success. The ability to share files seems to be based only on the level
of encryption I am using. Any help is certainly welcome.

Thanks,
Rich
