Network problems - DNS fault? - help

I am currently experiencing very long delays when logging on the domain from a client WinXP pc. Specifically the "Applying your personal settings" dialogue seems to stay on the screen for about 3 minutes.
I am sure this is something to do with the domain as I can log on just fine using the local administrator account. I am also experiencing delays with using Microsoft Exchange. (specifically exchange server unavailable etc, etc)

Now let me show you my current network setup:

I have a broadband internet connection which goes straight into my Gateway/Router.
This gateway/router provides DHCP to all my clients providing IP and DNS information. Clients have to get their IP address from here.

There is a Windows 2000 Server on the network which also recieves its IP address from here. This is a Domain Controller which also has DNS installed.

I take it this means none of my clients can register themselves with dynamic DNS?

If anyone can tell me whats happening on my network I would be really gratefull - thanks

Slow Win XP on Network

The FIRST thing to check Is the PC has Valid DNS server in its Connection Properties (Under TCP/IP) and the correct DNS suffix. You might want to try Adding Your Domain Controllers IP address in as the secondary DNS server.

*****Slow Startup*****

Correcting System Hang at Startup

If your system hangs about 2 or 3 minutes at startup, where you can't access the Start button or the Taskbar, it may be due to one specific service (Background Intelligent Transfer) running in the background.

1. Click on Start/Run, type 'msconfig', then click 'OK'.
2. Go to the 'Services' tab, find the 'Background Intelligent Transfer' service, disable it, apply the changes & reboot.

Start with giving your DC a static IP. In the TCP/IP settings on the server, the DNS entry should point *only* to itself. The DNS entries on the domain members should point *only* to the DC as well. For external lookups, delete the "." forward lookup zone in your server's DNS if present (and configure forwarders). Check out the FAQ for more information.
Disable DHCP on your router. Enable it on your DC.

OK i cannot disable DHCP on the router - this has to be enabled.

WIll this cause a problem?
Sorry, I wasn't really clear. Of course you shouldn't disable the router's DHCP *client*; you'll need this for your connection to your ISP ...
What I meant to say was to disable the router's DHCP *server* component (which should be possible) and install a DHCP server on your DC instead (unless you can specify that your router's DHCP server should hand out only your DC's IP address as DNS server, instead of its own address).
