File sharing across 2 PIX 501s with NAT

I have a LAN (10.10.50.0) behind a PIX 501 (PIX-01) with all internal
machines NATTed to the outside IP as a Pooled address. Across the hall
I have a server stack (192.168.200.0) behind another PIX 501 (PIX-02)
with static NAT addresses to each server. The 2 PIX boxes are
connected across a hub. The outside addresses of the 2 PIXes are
public addresses on the same subnet.
I want the LAN machines to be able to access file shares on the servers
in the stack. So I opened PIX-02 to all incoming traffic on all ports
for packets originating from the PAT address of PIX-01. PIX-01 is
completely closed to incoming traffic.
This worked OK, but the file sharing has intermittent problems. For
example, in the middle of copying a bunch of files from LAN machine A
to server B, the process dies with a message that the network
destination is no longer available. Also, some file types (ArcView
..mxd files) had frequent errors when opening (but still intermittent).
What am I missing? Please don't suggest a VPN (;->) as I already tried
that and, while it solved the file sharing problems, it is abysmally
slow.
Thanks for any help!
John H.
