No. The $TTL only affects the TTL values on the resource records in
the zones your server loads. If you're having problems resolving
names, it has some other cause. Maybe there's a weird forwarding setup
or your servers forward to flaky name servers? Maybe your firewall is
blocking DNS traffic? Maybe you restarted old name servers that are
allowed through the firewall? These are just guesses. You didn't give
any information about how DNS works at your site which would allow
someone to pinpoint the problem.
