Now you need to go to your DHCP server and set predefined options for wpad. I suppose all should be good thereafter. http://technet.microsoft.com/en-us/library/cc713344.aspx Good luck ________________________________ From: "Ball, Dan" <DBall@xxxxxxxxxxx> To: "isalist@xxxxxxxxxxxxx" <isalist@xxxxxxxxxxxxx> Sent: Fri, January 8, 2010 4:24:14 PM Subject: [isalist] FWClient DNS Issue Interesting problem here, thought I’d ask you guys about it first… I am working on replacing my Domain Controllers with Server 2008 R2. Recently, I pointed all the DNS servers to the new R2 servers instead of the 2008 SP2 servers. Now the Firewall Client will not automatically detect the ISA server. I traced it back to the wpad DNS entry. In the DNS server, the wspad and wpad entries are Aliases (CNAME) for the ISA server. When I do an nslookup from a workstation, I can resolve the wspad entry, but not the wpad entry (cannot find, non-existent domain). I can delete the Aliases from the server, and watch them replicate between the different servers, so I know the settings are working. When I launch the nslookup console, I cannot resolve wpad from the R2 servers, but if I attach to the SP2 server it resolves it correctly. Any ideas why Server 2008 R2 will selectively choose which DNS aliases to ignore? -------------------------------------------------- Dan Ball Network and Systems Technician Marquette Area Public Schools 1103 West College Avenue Marquette, MI 49855 E-Mail: dball@xxxxxxxxxxx Phone: (906)225-5779 Fax: (906)225-5377 --------------------------------------------------
