Ehren, The clients generally use campus dhcp, so it looks like they get 255.248.0.0 for a subnet mask. I'll have to check whether I used that, or 255.255.255.0 on my static address servers. Yes, I had to configure all the clients to use my DC for dns, otherwise they couldn't login. But I am still having problems connecting to other network resources, or authenticating on them. -John On Jun 12, 2009, at 1:02 PM, Ehren Benson wrote: > Assuming your domain controller is a DNS server also, which it > pretty much has to be you NEED to point your client DNS to the DC to > process logins.
