We have a Windows Standard Server 2003 AD domain with 14 client XP Professional computers. Each day we turn on the computers and find the last 4 computers we turn on (we've tried turning them on in different orders, it doesn't make a difference) take 5 - 10 minutes "Applying computer settings" and then do not have the ability to view web pages. All clients are able to ping the AD & DNS server and are able to successfully ping external domain names via the command line. All 14 clients are able to run client/server applications and view the network. Is it possible that CALs are limiting the connection to the internet on 4 computers? I know we have 10 CALs (per server mode). Any ideas would be greatly appreciated.
