Hey guys ive just done a fresh install of win2k3sp1ent with dhcp/dns/ad and dhcp was reciving a ip from our router and the dhcp was sending clients ips but after i installed ISA2k4 the dhcp stoped recving and sending, ive made the policies allow all trafic if its 192.168.0.0-192.168.0.255 and the local host

Any ideas?

I must ask to clarify...are you are currently running 2 DHCP servers on your network?

Sounds like you are getting a server IP from the router and then having DHCP on the Windows box hand out addresses? This configuration will not work. Turn it off on the router and use the Windows box to issue out addresses. Give your Windows box a static IP address as well.

No server should be getting a DHCP address from a router, period. Servers should always have static addresses. No, it's not a must, but it sure is recommended. So whether it's LAN or WAN, set it up to use static addresses.

Have you setup DNS and DHCP correctly? (Have you ever set it up before in a similar environment?) Have you created a DHCP scope and activated it with the necessary settings?

Well as i said everything was working fine before ips were sent out by dhcp but dhcp just stopped handing them out when isa2k4 was installed, and yes ive looked over all dhcp settings to make sure its activated and all

      Nothing is stopping you from continuing with your testing cadence. If updates are released every 2 weeks instead of 4, and you test once every 4 weeks, the exact same amount of patches will still be available for you in those 4 weeks. For example: Before 4th week - patch 1, 2, 3, 4 After 2nd week - patch 1 and 2 4th week - patch 3 and 4 Still the same amount after 4.

      Everyone else has said it. I'm gonna say it - you don't know what you're talking about. I do. I have two laptops. One work, one personal. I have access to two more laptops - both personal. At home I manually update my personal laptop when I see on Neowin that there is an update - I carry on and only apply the updates when I am ready. My work one only updates when my workplace decides to send it - I carry on and only apply the updates (when they actually arrive, which is usually days after the release) when I switch off the laptop at the end of the day as usual. The two other personal laptops only get updated when I get to it which is rarely - the people who own them carry on using them until I get to it and update them. All of the browsers on all laptops are configured to restore the tabs when launched. Google and Microsoft have changed from 6 weeks to 4, and it looks like it's going to move to 2. None of these changes affect how any of these browsers on the laptops are used. Not one jot. My advice to you is stop panicking whenever you see an update. Just carry on with what you're doing. This even benefits you in a way - from your comment you sound like you don't like the changes or the frivolous new features - great - then carry on as before!
