Csa 5.2 defining dns suffixes as home nets

I am struggling to find any documentation that tells me how a system state defined by dns suffix is parsed. If i look in the dns suffix list (ipconfig /all) my local dns suffix for the company is always present, even if i am offline, this is also true at customer sites, they have their primary dns suffix in the list always, no matter where they are. I am wanting to use dns suffix to define an offline/online policy, since ip and mngt center reachable/unreachable is unacceptable, no supported redundant csamc and ip is just useless to define this function. Anybody tried to do policies like this ?

Hi Jan, it sounds like the machines in question have the DNS suffix appended to the computer name. These will always appear in the suffix search if that's the case.
Connection-specific or dynamic (DHCP) DNS should work for what you are trying to do.
I tried it and it seems to work as expected.

How to change the DNS suffix from "home" on home h...

Strange question: I noticed with the DHCP lease coming from the HomeHub that there is a DNS suffix applied of "home".
I use a VPN connection to the office and I want it to take the VPN DNS suffix which it used to do on my old router where there was no other DNS suffix.
How can I remove this on the HomeHub? I have looked around in the DHCP settings in advanced mode but it isn't advanced enough!
I have got round the issue by adding the addesses on the VPN to my local hosts file, but I want a proper solution.
Any ideas how I can get really behind the scenes on the Home Hub?

It wasn't anything to do with the DNS suffix afterall (not that I could find where to change it).
From looking at other posts about VPN, it was to do with the BT automatic redirecting on DNS error which is automatically enabled.
Once I disabled the setting (can't remember the link but it is easy to find on the forum) then all my VPN addresses were working again.
Quite why BT would automatically enable a "service" that breaks a simple thing like a VPN connection is beyond me.

Wrt160n connection specific dns suffix

I have a WRT160N router that has been working great until I switched to a new ISP. The router configurations stayed the same, I just switched from a DSL modem to a cable modem (Motorola SB5100). The problem is the "connection specific DNS suffix" is being appended to the computer names and returning an incorrect IP address. Internet access is working fine. It appears that the DHCP is allowing the DNS suffix from the modem to push through to the DHCP clients.

Sorry about the misleading computer name, I'm not using a server for my DHCP. I'm using the router (WRT160N) as the DHCP server. This is just a home setup with 4-6 computers networked together. I use file sharing with the computer I call "home-server". I use RDP to connect to the other computers. Now when I try to connect to another computer with just the computer name, the remote desktop fails to find the client. If I RDP the client computer with the IP address it connects, no problem.
Netbios over TCP/IP is enabled.

How to define 'home net.'?

I am the owner of a Nokia E61. I have configured my WLAN that I use at home without a problem. I am able to retrieve email over this connection.
Now I would like my E61 to automatically retrieve headers when I am at home (through the WLAN - so not when I am travelling and my WLAN is not in reach).
So I go to 'Messaging -> Mailbox name -> Options/E-mail settings -> Automatic retrieval' and try to change 'Disabled' to 'Only in home net.'.
Then it says 'Unable to retrieve headers. Define access point first.'
So how do I define what is my 'home net.' access point?? I have defined my WLAN but how do I make it my 'home net.'?
Am I missing something here??
Thanks, Rene.

Hi,
To define the home network, you just need to go to the settings for the email account you want to set up. Go to Connection Settings -> Incoming messages. Set up whatever network you want to use (either wifi or whatever) in Access Point in use (when you go in there, select "user defined" first, and it will show you a list of access points defined in the device).
I hope this helps!
Jordi
PS: I've followed the steps in an e65, but it should be pretty much the same.

Switching from custom DNS suffix at work to no suffix at home with Access Connections

I have 2 profiles defined in Access Connections: (1) Home, (2) Work.
At work, I need to have custom DNS suffixes defined to help find certain servers, e.g., development.int and marketing.int. Notice that the TLD is "int", meaning it only resolves using our company's internal DNS servers. In the Work profile, I selected the Override TCP/IP settings option and entered the suffixes in the Advanced DNS Settings dialog.
However, at home, I do not have a need for these work related private DNS suffixes, and I don't want the system to try to append these 2 suffixes to the search order. I tried the following Advanced DNS Settings: (1) Use current advanced DNS settings, (2) Use the following advanced DNS settings / Append primary and connection specific DNS suffixes.
When I come home from work, Access Connections automatically connects to the Home profile, detecting my Home WiFi network's SSID.
However, when I try to login to a server at home, e.g., media_server, using PuTTY, the system tries to connect to media_server.development.int instead of *just* media_server. I, then, need to go to the TCP/IP settings manually and remove the DNS suffixes.
How would I configure Access Connections so that when I come home from work, it doesn't keep appending the work related custom DNS suffxes?

Could not find what you mentioned above.
I can go to "Additional Settings" tab, click "Settings" next to Override TCP/IP and DNS settings, click "Add Advanced DNS Settings".
At this point, I have 2 choices: (1) Use current settings, and (2) Use the following advanced DNS settings.
(1) would not work, since "current" would refer to my Work setup that *already* has the DNS suffixes entered in the search order. If I choose, (2) and just leave it at "Append primary and connection specific DNS suffixes", this DOES NOT remove the existing list of suffixes from the TCP/IP stack configuration.
Other than going into the Windows network adapter configuration UI for TCP/IPv4 and removing the sufixes manually, there is NO other solution at this point in time.
The other solution that you propose of using a script doesn't work in an automated way, as in using it in the "Start an application automatically" setting, since these types of operations require Admin privileges, and I get an "Access denied" error back at the console session that runs my script (pasted below for reference):
noDNSSuffix.cmd
===============
cscript "c:\Users\JohnDoe\Documents\Scripts\noDNSsuffix.vbs"
noDNSSuffix.vbs
===============
strComputer = "."
Set objNicConfig = GetObject("winmgmts:" & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2").Get("Win32_NetworkAdapterConfiguration")
intSetSuffixes = objNicConfig.SetDNSSuffixSearchOrder([""])
WScript.Echo VbCrLf & "intSetSuffixes: " & intSetSuffixes
It'd be nice if I could ask Access Connections to explicitly REMOVE any DNS suffixes defined. In doing this, it would need Admin privileges, so you may need to use something else in the ThinkVantage toolset (UACSdk.exe ?) to give it the Admin privileges WITHOUT prompting the user to click the "Yes" button.

Csa dns suffix wildcards in system state

Has anyone tried using a dns wildcard in the system states ? I have a customer that uses something.net as common dns, but locally they get assigned to stuff like 123.something.net. If i use *.something.net it doesn't match, *something.net is a nogo as well, how is it supposed to be used ? do i really need to find all the subdomains and add these ?

I think dns suffix matching field in system states sets can be used for this. Following link may help you

DNS Suffixes

Is statement below true ? I can't find any information relating to the
maximum search entries you can define that is feasible, whether its
thru GPO or connection-specific settings.
"The DNS suffix search list can only contain a list that
can be searched in a maximum of 12 seconds, this translates to
around 10 entries. Anything more than that will result in failed name resolution
unless WINS is still being used. "
Regards,

Do not configure DNS suffix settings through a GPO, its unreversable and nasty. To reverse it you need to modify a registry key on every workstation, or do a ADSI Edit workaround.
By default, the Primary DNS Suffix of a member computer of an Active Directory domain is configured to automatically change when domain membership of a computer changes, or if the DNS name of the domain to which the computer is joined changes. This automatic DNS Suffix update change is controlled by this registry key:
HKLM\System\CurrentControlSet\Services\Tcpip\Parameters
REG_DWORD SyncDomainWithMembership is set to 0x1
This is default for every Windows 2K/XP/2K3 PC.
If you enable a Group Policy object which applies the DNS Suffix to all workstations under Computer Configuration --> Administrative Templates -->
Network --> DNS Client, what this does is permanently change the default behaviour by deleting the SyncDomainWithMembership registry key from all Member Computers and adding a new registry key under:
HKLM\Software\Policies\Microsoft\System\DNSclient
If a previous administrator has done this, you can either setup a method to re-instate this registry key on every PC in your domain, or create a workaround using ADSI Edit to configure Active Directory to accept multiple DNS suffixes.
The work around:
1. Open up ADSIEdit and connect to the Domain Partition.
2. Right click on the domain root and go properties.
3. Modify the msDS-AllowedDNSSuffixes multi-valued attribute and adding in all DNS Suffixes you have on your domain.
Sorry I didnt answer your question directly and going off topic but I hate when Administrators configure DNS suffixes through means of GPO because it does cuases these annoying problems especially if you ever need to do a Domain Migration or Domain Rename.

Windows DHCP add DNS Suffixes, Option 119

Hi, in Windows DHCP i need to add a DNS suffix (option 119), but it seems that it only accepts values in Decimal or Hexadecimal
If i want to add the suffixes
'mycomp.com','comp.mycomp.com'
I will need to convert this to decimal or Hex first..
function Create-ValidDNSSearchListHex ($Strings){
foreach ($String in $Strings){
foreach ($Part in $String.split('.')){
$R += "0x{0:X2}," -f ($Part.Length)
$ans = ''
[System.Text.Encoding]::ASCII.GetBytes($Part) | % { $ans += "0x{0:X2}," -f $_ }
$R += $ans
$R += "0x00,"
$R.Trim(' ',',')
Then i use the fubction to convert my strings
$sfx =Create-ValidDNSSearchListHex 'mycomp.com','comp.mycomp.com'
And when i try to add the option it fails
Set-DhcpServerv4OptionValue -scopeid 10.25.55.0 -OptionId 119 -Value $sfx
error:
Set-DhcpServerv4OptionValue : Parameters for option value to be set for option ID 119 do not match with option definition on DHCP server DHCPserver-01.
At line:1 char:1
Any ideas how can i fix this?
Thanks

Read this including the comments. The option is only for NON-Windows clients and does not work as defined:

Set Primary DNS Suffix Using Powershell

For a Windows Server 2012 installation, what Powershell cmdlet can be used to change the Primary DNS Suffix ? I've tried using 'Set-DnsClientGlobalSetting -SuffixSearchList contoso.com' but this only alters the DNS Suffix Search List, not the primary DNS
suffix.

You might want to take you question to one of two forums that specialist in scripting issues.

Adding multiple dns suffix

hello
is it possible to add an ADDITIONAL dns domain suffix to my W7 and maybe some XP machines, via GPO?
thank you

Hi Christopher Ream,
As the Help of this setting says,
the value of the DNS suffixes in this setting may be set using comma-separated strings.
As RFC 398 document says, This specification uses the Augmented Backus-Naur Form (ABNF) notation of [RFC2234],
including the following core ABNF syntax rules defined by that specification: ALPHA (letters), CR (carriage return), DIGIT (decimal digits), DQUOTE (double quote), HEXDIG (hexadecimal digits), LF (line feed), and SP (space). Personally speaking, space
is a reserved character which is not recommended to be used in the domain name to avoid misunderstanding. What's more, this setting doesn't use comma+space as separated strings which can help to reduce the workload of resolving package.
However, these are my personal guess. Hope that helps!
For your information, please refer to the following article to get more help:
http://tools.ietf.org/html/rfc3986#page-11

Adding DNS suffix to VPN

I'm trying to add a DNS suffix to a VPN that I create to a windows 2000 server. On Win XP, I bypass the default gateway and add the dns suffix xxxxx.local and things work correctly. I'm not sure how to do this on OSX.
Any tips much appreciated

The DNS configuration, including DNS server addresses and search domains, is pushed out from the server when the client connects.
Therefore there should be some setting in the server that lets you define what the clients should see/use when connected. I'm not familiar with the Windows VPN server to know how to advise further.

RVS4000 DNS Suffix - How to change?

I installed an RVS4000 router in my home network. When i try to ping a machine by name it resolves to some funky ip address not on my network. I noticed that my machines are now named MACHINENAME.RVS4000. the RVS4000 domain actually resolves to some IP. how do i go about changing this for my network?
thanks
GK

It wasn't anything to do with the DNS suffix afterall (not that I could find where to change it).
From looking at other posts about VPN, it was to do with the BT automatic redirecting on DNS error which is automatically enabled.
Once I disabled the setting (can't remember the link but it is easy to find on the forum) then all my VPN addresses were working again.
Quite why BT would automatically enable a "service" that breaks a simple thing like a VPN connection is beyond me.

Setting the DNS Suffix in Windows-2000:

This is a solution for the frequent problem that arises during installation of iPlanet Application Server on Windows-2000 platform.
Problem: After installation completes, the installation directory remains empty, there is no entry of iAS in "Windows start menu". It doesn't install anything.
Remedy: Set the DNS Suffix.
Procedure:
Right click on My computer (icon on desktop or in windows-explorer), then click on properties, go to Network identification Tab, Click on properties, then click the more button, set the Primary DNS suffix (like india.sun.com), and also check the Change Primary DNS suffix when domain membership change check box, click all Ok buttons.
Note:
1. Make sure that it is added to the windows registry:
Just run regedit and click on the My Computer\HKEY_LOCAL_MACHINE\SYSTEM \ControlSet001\Services \Tcpip\Parameters key, you will see the Domain key value set to your domainname, otherwise enter the domain name into this key value, and than reboot the m/c, and than reinstall the iAS. It should work.
2. Make sure you are using static IP address.

Thanks Sanjeev Agarwal

ASA Remote Access VPN Clients - Multiple DNS Suffixes?

Hi community!
I am setting up a new remote access VPN using the traditional IPSec client via ASA 5515-X runnning OS 8.6.1(5).
We require to provide each client multiple DNS suffixes, but are only to provide a single DNS suffix in the grouip policy.
I have tested using an external DHCP server, but using our Windows Server 2008 infrastructure and Option 119 the list is not provided to clients, and I have read that Windows 7 clietns may ignore this option anyway.
Other than umanually configuring the clients , does anybody have any other suggestions on how we may get this to work?
Full marks for helpful posts!
Kind regards, Ash.

Hi
I am looking into the same issue, and I am finding conflicting documentation about this and wondered if you got the answers you were looking for.
I have a remote access requirement for users from separate AD's to authenticate through an ASA.
I was reading about Global Catalogue Server but this is not specifically what I want; and also creating a new AAA server group but the user would need to accept which group to use when they log in

Apache/Portal working with 2 dns suffixes

I have 2 different DNSs on the network which currently access the intranet. One has the DNS suffix .name.org the other .name.local. How do I get Apache to work with both and for the login server, etc. to work with both? You can't just enter hostname:port for the login server, and seems to require the full DNS name (suffix included), which can change depending on which DNS the user is using.
