squid proxy

I have squid proxy on suse enterprise linux 11.2, for some maintenance puposes i have to swap the proxy ip with Windows ISA server. after that my squid is not working,so i am getting the following error in my access log file and none of user is able to browse the internet.

1382609509.685 239818 172.16.225.203 TCP_CLIENT_REFRESH_MISS/504 0 GET http://dnl-07.geo.kaspersky.com/index/u0607g.xml.dif - DIRECT/130.117.190.137 text/html

one more thing i am getting the different dns records in nslookup query

while i checked in the dns server there is only one record against the proxy with the new ip but on the linux machine itself there are three records.I have cleared the cache uodated the dns record even restarted the proxy server but in vain.

40.0.16.172.in-addr.arpa name = isa.abc.local
40.0.16.172.in-addr.arpa name = proxy-web.abc.local.
40.0.16.172.in-addr.arpa name = proxy-server.abc.local

What does this mean? Proxy has no wan connectivity?

There are many reasons why you could get those PTR's, most likely they are in the DNS you do your lookup against - and a left over from the IP switching. But don't worry, they to no harm and have nothing to do with your current problem. Consider cleaning up your reverse lookup zones to get rid of those PTRs.
