How is your directory configured?
How many servers/sites?

I know mine takes 'a while' - but 5-10 is a bit much...
Ours typically is about 3-5...

Hi smantha1979,

If the server isn't a very powerful machine or isn't connected to a network hub/switch then you'll get a long wait.

Check the network cable is connected and post up the specs of your machine.

If you have 2 network cards in this server, make sure the primary (internal) NIC is at the top of the binding order.

Sounds like a DNS problem.

Make sure your NIC has the DNS setting for only itself.
You can set Forwarding up so that it will forward internet requests to the ISP - no problem.

Also, make sure all your workstations only use your server for DNS.

i have a router connect to a cable modem, and my server connects to the router,, my other computer get the ip from the router's dhcp, is it ok to use router's dns server for workstations?
i can connect tothe internet and resolve domains, so the forwarding part would be fine..
the server is fine,, just start so slow,,:(

That's why.  When you install Active Directory it needs DNS that supports Dynamic Updates.

It's fine to have DHCP on the router, just make sure the server has a static address and you are using the server's DNS - things will work much better that way.

i had set the forward zone with dynamic update supported,, and i had manually config the static address before i setup the active directory.

Ok.  Do you point the DNS server (yours) at itself for resolution?

Do you have the ISP's DNS server listed on your NIC?  if so, remove it there.  Your Forwarder will handle this.
