RE: [ActiveDir] DNS issues?

[Michael B. Smith]

We do our dhcp in our PIXen, a sample config for a small remote location is below.   The one thing I would want you to test is to see whether you have the DNS UDP and TCP ports open across the VPN. It sounds as if you do not.   dhcpd address 192.168.100.100-192.168.100.149 inside dhcpd dns 192.168.100.161 dhcpd wins 192.168.100.159 dhcpd lease 3600 dhcpd ping_timeout 750 dhcpd domain brnets.local dhcpd option 150 ip 192.168.100.7 dhcpd enable inside From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Todd L. Graham Sent: Thursday, May 13, 2004 8:30 AM To: [EMAIL PROTECTED] Subject: [ActiveDir] DNS issues? I have a problem with my DNS over the WAN and VPN.  Here is the issue.  For some reason DNS will not resolve names over the WAN, or VPN.  I can only connect to resources by IP address.  This problem started when I upgraded my network in January.  We switched to a Cisco IP phone system along with all Cisco gear (VPN concentrator, PIX firewall, switches, routers…lots of money spent).  We also upgraded our network at the same time from W2k to Server 2003.  We have a Point to Point T between our sights and a T1 for internet access here.  We have about 30 people who VPN into the network on the VPN concentrator.  Our AD (I actually run all IT for 3 companies, same owners) is one Root domain with 3 child domains 1 for each company.  All common resources and user accounts are in the root. Computer accounts and private resources are in each child domain.  The child domains share nothing. Due to the phone system we have several V-LAN’s one for voice, VPN, Guest, and computer network.   When I am at the other location I can’t browse the network, or attach to mapped drives from my logon script (they don’t even appear).  I can only attach to resources if I create a new mapped drive by IP address.  When I do an IP config I get all the right DNS servers listed.  I can only ping them by IP address.  The same situation happens when I VPN from home.  We had DNS only on the network.  My Cisco vendor told me it’s not their gear.  I added WINS to see if this would help…it did not. Any suggestions on what I could have configured incorrectly?  Could it be the Cisco routers?           Thank you for the help!      Todd Graham IT Manager Urell Inc. 617-600-9355 [EMAIL PROTECTED]
