LinuxQuestions.org - Changed IP scheme on network, Samba browsing really slow

Last night i changed my ip scheme that my network is on, from 192.168.1.* to 192.168.15.*. I have a gentoo system running a 2.6 kernel being used as just a samba server. I edited my /etc/conf.d/net to reflect the new chanes in ip. Then i changed my smb.conf on the hostsallow list. I use swat, so i updated the swat config file to allow access by system on the 192.168.15.* network. Now, browsing samba shares there is a delay of about 15-20 seconds, where before it responded imediately.

Here is my smb.conf file.
# Samba config file created using SWAT
