Hello, Try the following command on the isa server. ipconfig /flushdns It is possible that the ISA servers DNS cache is polluted. This will clear the DNS cache. If that is causing the problem.

Now my other ISA servers resolve fine...in fact if you simply point a client to a different ISA Server...and refresh..MS comes up..then switch back..and its back to "Mr Dog" again. This would seem to me an obvious ISA cache problem no? I changed the ISA Cache to 5megs...restarted...then changed it back to 1GB....however it still happens. I guess its possible the MS.com cached page was within that 5megs...but that seems highly unlikely. ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=isalist ISA Server Newsletter: http://www.isaserver.org/pages/newsletter.asp ISA Server FAQ: http://www.isaserver.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Other Internet Software Marketing Sites: Leading Network Software Directory: http://www.serverfiles.com No.1 Exchange Server Resource Site: http://www.msexchange.org Windows Security Resource Site: http://www.windowsecurity.com/ Network Security Library: http://www.secinf.net/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: wtholmes@xxxxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
