I'm having a weird problem right now with a setup at a business.
DSL > Pix 501 > win2k3SBS > Clients (win2k,xp,98)
Currently the win2k3 machine is hosting the DNS and is also the domain Controller. The domain name is companyname.internal .... so active directory did its thing and setup the dns server on the same machine.
The IP Address of the win2k3 machine is 192.168.5.3
The Gateway is 192.168.5.1 (Pix)
The DNS Server is 192.168.5.3
I checked the DNS Server on the win2k3 machine for the infamous "." zone and it wasn't there. I also put my ISPs DNS Servers in the Forwarders
Right now the win2k3 machine is also the DHCP server and it's giving out client IPs in the form of
IP: 192.168.5.50 - 192.168.5.100
Now - the entire internal network has been kind of flaky after the addition of the win2k3 machine. It used to just be DSL > Pix > Clients and all was fine.
Now after joining the clients to the domain it seems like randomly they'll not be able to connect to the domain and also not be able to get any outside internet traffic. They *always* have internal ip, ipconfig /renew/release always works, and they can ping anything on the internal network, just sometimes they'll say "Domain is not available" and hte like. Now, the machines that are able to get onto the domain, every now and then for some random reason they'll lose internet connection. what i mean is, you can do ping www.google.com
and it'll resolve the IP through DNS for google, but all the requests will zero out... then suddenly it'll start working. It's really strange. I don't know if this is a pix problem (as it never happened before) or if this is b/c of the new win2k3 domain machine. The win2k3SBS server has 5 CALs - they have 10 machines at this office, but 1/2 of them are just dummy machines that host UPS (shippers) printers and software, so i interpreted the CALs as user CALs. Despite if this breaks any licensing agreements, would this be the reason the computers randomly lose connection? are they fighting for licenses? Is there a way to fix this by perhaps having the PIX give out the DHCP leases, so that only when the computer is trying to use the domain (shared drives) they fight for licenses? It's just really mind boggling that the connection is in and out like that, one second they'll all be down, the next second they'll all be up, then later 1/3 will be up - it's just weird.
Any advice/suggestions would be nice. I have an extra 5 pack of device CALs on the way to hopefully remedy this, but i'm doubtful that'll do it.
