Only 10 internet connections for a domain?

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.

It is best to have as many CALs as you do users, and in this case, I would add another 5 (1 pack).

Do you have a firewall type router that limits you to 10 connections. I have seen that before at clients.

What firewall/router do you have? I would start looking there.
Are you running a proxy server of any sort? (Licensed for 10 users perhaps?)

We do have a Cisco PIX 500 firewall in place. I was assured it does nothing more than create a secure tunnel for specific file transfers from another site. The other site will not allow access to the PIX configuration. I'm attempting to rule out everything else before jumping into that bureaucratic nightmare. I'm afraid that may be the cause however.

I would suggest you remove the firewall and go straight to the internet with a cheap router FOR TESTING ONLY.   Just to be 100% certain it's not some kind of router/firewall configuration issue because this sounds a LOT like a firewall/router limitation on some older models.

If its a PIX 501, I would agree with Thorrsson and leew and guess that it is only licensed for 10 hosts.

If you ask the people that manage it to do a "show ver" it will probably look like this

Thanks everyone. It was definitely the PIX firewall's limitation. Replaced with a new firewall and all is well. Added 5 more CAL's as well, though that was not the issue.
