RE: [ActiveDir] (OT) DNS settings

Title: Message

Not a problem I might have overlooked something and thank you for taking the time to help.   Ok – Yes we use DHCP. No Static IP addies. Machines are all different models and NIC’s I could disable the internal NIC – why would that make a diff (just trying to understand the logic?)   From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Rutherford, Robert Sent: Tuesday, May 11, 2004 2:21 PM To: [EMAIL PROTECTED] Subject: RE: [ActiveDir] (OT) DNS settings   I take it that you also use DHCP in your internal networks, i.e. you don't assign static IP's to your internal NIC's? As a test could you just disable the internal NIC and try the dialup again?   Are all the machine exactly the same, i.e. same model with same NIC's?   Sorry if I seem to be shooting all over the place but we will home in eventually. -----Original Message----- From: Carlos Magalhaes [mailto:[EMAIL PROTECTED] Sent: 11 May 2004 13:11 To: [EMAIL PROTECTED] Subject: RE: [ActiveDir] DNS settings DHCP Enabled. . . . . . . . . . . : Yes Autoconfiguration Enabled . . . . : Yes IP Address. . . . . . . . . . . . :  196.2.45.82 Subnet Mask . . . . . . . . . . . : <ispSubnetMask> Default Gateway . . . . . . . . . : <ispGateWay> DHCP Server . . . . . . . . . . . : <ispDHCPServer> DNS Servers . . . . . . . . . . . : <internal/localDNS>   From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Rutherford, Robert Sent: Tuesday, May 11, 2004 12:05 PM To: [EMAIL PROTECTED] Subject: RE: [ActiveDir] DNS settings   For some reason I thought you were using a VPN to connect.... I'm an idiot and should have read the detail.   Can you humour me and just post an IPCONFIG /ALL dump from a troubled client.. just type local DNS in place of your internal IP range if required.   Thanks,   Rob -----Original Message----- From: Carlos Magalhaes [mailto:[EMAIL PROTECTED] Sent: 11 May 2004 10:03 To: [EMAIL PROTECTED] Subject: RE: [ActiveDir] DNS settings Hey Robert,   Ok there is nothing wrong with the internal DNS at all, they can resolve everything they want when logged onto the network.   Their problem is when they go home and are off the network they use their own third party ISP accounts with the default windows dialer to create a 56k Dial up PPP connection to a third party ISP. This is for their own email and internet usage. At this stage (when they dial up) they are not connected to us in any way what so ever.   What I am finding strange is that the ISP usually assigns them a valid IP, DNS and gateway from the ISP’s DHCP server. The weird thing here is that they are assigned a valid IP and gateway but the DNS servers for that PPP connection is using our internal DNS server address. Which causes a nightmare when they try to resolve names while connected to the ISP.   As you can see the ISP can not resolve names cause its trying to use the DNS settings of our internal network….   That’s what I don’t get and I don’t get why its doing this either L   Thanks for your time.   From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Rutherford, Robert Sent: Tuesday, May 11, 2004 10:53 AM To: [EMAIL PROTECTED] Subject: RE: [ActiveDir] DNS settings   Sorry I think I have lost track here somewhere... I probably didn't read your problem correctly.   I would actually think that it is better for them to resolve to your internal DNS servers. I have seen loads of issues with people trying to get it to work the other way round. The only thing is that do your internal DNS servers forward out? If they did then you would probably be in an ok situation?   I'd still like to find out how your machines are getting their DNS entries though?? Strange.     -----Original Message----- From: Carlos Magalhaes [mailto:[EMAIL PROTECTED] Sent: 11 May 2004 09:14 To: [EMAIL PROTECTED] Subject: RE: [ActiveDir] DNS settings We haven’t and still don’t use WINS , this network only uses DNS.   The problem I am having is that the user logged onto our network can work fine DNS is working etc. The user dialed up to their own ISP’s are being forced to our internal DNS servers, they still get a valid IP addy from the ISP they just are “forced” to use ours…       From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Rutherford, Robert Sent: Tuesday, May 11, 2004 9:56 AM To: [EMAIL PROTECTED] Subject: RE: [ActiveDir] DNS settings   It's either got to be WINS or Hosts files while using the standard W2K VPN dial-up. I don't think WINS is a bad solution to be honest.... unless you want to dig into your pocket.    If you use a 3rd party, i.e. Checkpoint, then their technology allows for overlay of your DNS setting post connection. I mentioned IPass earlier and they can do a similar thing with their client, i.e. push on your internal DNS server post connection to an IPass ISP.     -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Rick Reynolds Sent: 11 May 2004 08:14 To: [EMAIL PROTECTED] Subject: RE: [ActiveDir] DNS settings I have always pushed lmhosts and hosts files to the machines...   -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]On Behalf Of Carlos Magalhaes Sent: Monday, May 10, 2004 11:38 AM To: [EMAIL PROTECTED] Subject: RE: [ActiveDir] DNS settings Nope that’s what gets me, and its happening to ALL the laptops, (they are the only machines using third party dialers)   AGRRR – there must be an answer :P   CM   From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Charlie Kaiser Sent: Monday, May 10, 2004 8:30 PM To: '[EMAIL PROTECTED]' Subject: RE: [ActiveDir] DNS settings   Is there any hard coding of DNS settings on the laptop's network connection properties? This will override any server-assigned DNS settings...     ********************** Charlie Kaiser MCSE, CCNA Systems Engineer Essex Credit / Brickwalk 510 595 5083 ********************** -----Original Message----- From: Carlos Magalhaes [mailto:[EMAIL PROTECTED] Sent: Monday, May 10, 2004 11:15 AM To: [EMAIL PROTECTED] Subject: RE: [ActiveDir] DNS settings Hey Al,   Yeah all the settings are suppose to be set via the ISP , most ISP's run DHCP so yes the settings should be set. The weird thing is that only the DNS settings are being forced to our network, the user gets a valid third party IP address and default gateway, just not a DNS setting, that's what made me think it might be something on our network.   We done run WINS just DNS.   Thank you and Keep well!   CM   From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Mulnick, Al Sent: Monday, May 10, 2004 4:31 PM To: '[EMAIL PROTECTED]' Subject: RE: [ActiveDir] DNS settings   Trying to remember exactly, but wouldn't they get their DNS settings from the ISP upon connection either through their software locally or from their RRAS server?   Al   From: Carlos Magalhaes [mailto:[EMAIL PROTECTED] Sent: Monday, May 10, 2004 9:41 AM To: [EMAIL PROTECTED] Subject: [ActiveDir] DNS settings Hey all,   I have a weird issue; all our laptop users have their own third part dial up's (RRAS and RAS) for their convenience. When the users dial up to their third party ISP's (all users) they obtain an IP address from the ISP but their DNS settings are being forced to the networks internal DNS servers, remembering that this is a PPP connection.  This causes havoc on their dial ups. I have had a look at the DNS settings the GPO and even the DHCP server. I don't see anything that would force a PPP connection to use the internal DNS servers. The settings are not hard coded into the PPP connections IP settings.   Anyone have an idea of what this is or maybe I over looked something.
