NAT/PAT networking issue

When working from internal network to an external network
server, databases fail. We get disk write delayed failure.
Excel, Word and other DOCS work fine. Access is maybe more
DOS-like in that maybe port 445 or piped mappings aren't
taking because some external domains only have zone
transfers from DNS being pulled inside to DNS server. When
the NAT runs out it changes to PAT and databases fail but
only databases. Why is this? What makes this different than
other DOCS.

We have used DNS suffixes, we have them specified in
Intranet Security zones. Is there maybe a workaround? We
have only 4 PC's getting this error out of 120. Once it
starts you can't get it to stop unless maybe changing NICs.

Anyone?

What do you mean when NAT runs out it uses PAT? If you're using PAT, then
it is used upon configuration. How many addresses are in your pool? If you
only need 120 addresses, then why not just configure a x.x.x.x/25 pool and
eliminate PAT if it is an issue? The main issue with PAT is if your pool is
too large, you could run out of memory to maintain the list of all
translations if everyone connected at once.
