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

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.

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.

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.

Windows Server 2008 R2 System State Backup fails "the parameter is incorrect"

Hi,
I'm having the same problem as I've found in a few other threads.

I've tried running the vshadow.exe -wm2 > out.txt command and searching the output for invalid paths, but I can't seem to find any paths that looks incorrect.
I've also done a registry search under HKLM\CurrentControlSet\Services for the / character and didn't come up with any in any paths either.
The server is a pretty new install. DC, DNS, DHCP, File and Print services. It has been running in production for about a week for a small business. Their previous server desperately needed changing over, so it got pushed in fairly quick. I never assumed
I would have had trouble with the system state backing up!. It would be nice to get it working so I can sleep at night :). The old DC is still running, so all is not lost in a failure, but still... I guess also once I've demoted the old DC, I can restore AD
just by restoring the entire system image (Don't have to worry about USN sync if only single DC), but I would still like a system state backup.
Thanks, Ryan

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.

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

[SOLVED] Append DNS Suffixes

How can I append DNS suffixes to my network connection in Arch? I have 3 suffixes to add for my work VPN connection.
Last edited by derekr44 (2009-05-05 19:22:36)

Hi there, I've had the same problem, and fixed it the way you described!
At this point, I would, however, point out that this solution should not be required, according to the wiki entry for resolv.conf:
http://wiki.archlinux.org/index.php/Resolv.conf
It clearly states in the wiki article that:
...the domain name is determined from the host name and the domain search path is constructed from the domain name.
... so suppose that I had a host called "somehost.mydomain.com" (i.e., in the /etc/hosts file it says
127.0.0.1 somehost.mydomain.com localhost somehost
then surely the domain interpreted automatically is "mydomain.com" and the domain search path is ... probably "mydomain.com" as well. Why, when should I explicity state for every host on my domain that it's in mydomain.com, even when the FQDN given in /etc/hosts already implies that it should search there?!
Clearly, the wiki article is inaccurate, unless other users have had a contrary experience.

DNS suffix loss

Hello,
My MacBook air is configured with a Domain.
When i turn off then ON the Wifi, there is no more DNS suffix for the domain hosts. I need to add the domain suffix by myself to get it working. The serach in the domain works.
If i turn OFF/ON several times it sometimes get back in a normal way.
Thanks,

Change Connection broker DNS suffix

Hi all,
I have VDI infrastructure inside local domain. I want to change DNS suffixes of VMs and RD servers to external domain name and attach external wildcard certificate to connection.
Everithing is OK with VMs but when I tried to change DNS suffix for Connection Broker Server I got following error in sever manager:
The following servers in this deployment are not part of the server pool:
1. <Old FQDN of server>
The server must be added to the server pool.
If I add server with old FQDN in All Servers section by DNS search even if it cannot find anything then I can view RD deployment properties but I can't change RD Connection Broker name.
How to correctly change RD server's DNS suffix?

Hi Sergey,
When you need to change the name of the broker in a non-HA RDS deployment, you essentially need to wipe and re-create the RDS deployment. For example, remove all RDS servers from the deployment (except broker) , remove RDCB Role Service (which
effectively wipes out the deployment), rename the broker server, create a new RDS deployment, then add all the other RDS servers back into the deployment.
In many cases people do not want to rename their internal servers, so what you can do is change the published FQDN using the script below:
Change published FQDN for Server 2012 or 2012 R2 RDS Deployment

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

How to Delete Non-System State Backups in Windows 2008R2

Hello,
I am running a Windows 2008R2 server which uses Windows Server Backup to do the backups. We are using the backup-tool to create non-system state backups of the data-directories on this machine. The backup is done on a dedicated disk connected through iscsi
(to a Synology box). This backup disk has become too small and we have now replaced the Synology box with a bigger one. Here i created a new LUN again for the backup purposes.
Now for my question; The wbadmin.exe tool supplied with W2008R2 does not offer a way to delete the old backups. I know that in Win2012 (which we we also have running) I could add the new iscsi location and then (when enough backups are available on the new
target) use wbadmin.exe delete backup to delete the old non-system state backups; e.g.
wbadmin delete backup -version:08/07/2013-21:00
This (very undocumented) feature of Windows 2012 and higher works quite nice and is exactly what i am searching for on the W2008R2 machine; a way to delete the old backups (and under the hood delete the corresponding snapshots)
I've done quite a bit of research and it should be possible to do something similar in 2008 but then manually, The howto is described in the following link: http://blogs.technet.com/b/filecab/archive/2009/06/22/backup-version-and-space-management-in-windows-server-backup.aspx .
Basically it describes that you should use DiskShadow.exe to remove e.g. the oldest snapshot with a command like :
Delete shadows OLDEST \\?\Volume{7fc1871b-2e1f-11dd-a339-001e4fb7af35}
Windows Server backup (wbadmin) should then on the next run 'see' this deletion and update its list of available backups:
"You can perform the same steps manually to delete backups on demand. However, the backup catalog update cannot be done manually and it will happen instead during
the next backup."
I've done this on our box and it indeed removes the shadows from the list. However, in the Windows Backup 'dashboard' it still lists the backups as available. Also after a new backup has finished (according the the article this is when it should 'update'
its backup catalog). When I try to restore a backup from a date that i just removed it gives a nice message that this is impossible because the snapshot is not available (duh :)) ;
Unable to browse Local disk. The shadow copy of the backup stored on the backup destination cannot be found.
So it seems that the aforementioned method works; it removes the snapshot and frees diskspace, but it doesn't update the Windows Backup catalog. As a result the management tool (GUI) still lists the backups which are no longer available! How can i change
this? Is there any way to do this? I found one article which mentions that the Dashboard bases its screen on the Windows Logs and not on the actual VSS snapshots available:
http://forum.wegotserved.com/index.php/topic/23757-start-afresh-with-server-backup/ (WHS) In my situation however this seems unlikely because i don't have any logs that date back as far as my backups go.
In my opinion this is a real bug and it leaves us with a in-consequent backup schema. Does anyone have similar situations or even a solution to my problem?
Kind Regard, Martin

Hi Mandy,
Yes! I think i got my answer and I now get how windows backup works in Windows 2008 :-) It turns out that I dismissed some suggestions a bit too soon. The answer lies in the command mentioned earlier :
Wbadmin delete catalog
This command does delete all the backups from a perspective of the Windows Backup UI, but leaves the VSS snapshots intact. This means that the backups are still available, but you just can't restore them with the User Interface. In order to 'update' the
UI with the current available snapshots (which you can list with diskshadows list shadows all), you have to re-add the existing media on which the backups took place using the Wizard of the UI. It will then inform you that existing backups are available and
if you want to keep these for restore purposes. If you click 'yes', and THEN perform a backup ... All the current available backups will be shown in the User Interface :-)
So for my steps taken to change from one iscsi (iscsi1) to another (iscsi2):
- Add the 2nd iscsi target with the Windows Backup UI
using Backup schedule , Modify backup -> [desired options] => Add more backup destinations -> iscsi2
- Remove the 1st iscsi target with the Windows Backup UI
using Backup schedule , Modify backup -> [desired options] => Remove current backup destinations -> iscsi1
- Run some backups on the new destination. Old restore points are now still available. When enough restore points are available on the new volume iscsi2 start deleting old data from iscsi1 as follows:
- Run diskshadow
diskshadow
- list all the current snapshots
list shadows all
- remove all the snapshots of iscsi1 (repeat until all shadows are gone of iscsi1)
delete shadows oldest \\?\volume{yourvolumeid}\
- delete the windows backup catalog
wbadmin delete catalog
- Restart the windows backup UI and re-add your schedule on the new volume iscsi2. It will now ask if you want the keep the existing data for restore purposes; click yes.
- After the next backup only the backups of volume iscsi2 will be listed and everything is fine !
I Hope my post will help others with similar questions. It was quite a search before I understood the way it works. Basically as long as your VSS snapshots are still available and listed by diskshadow you still have the backups and you will be able to get
this in sync with the steps above (delete schedule and re-add originating targets containing the snapshots). After the next backup the UI will update itself.
(In my case someway along the way I lost my originating snapshots, but because I already had my new backup set it didn't bother me; It kept me from having to delete all 510 old backups :) with diskshadow)
Regard, Martin

Remote system state

i want to know whether the remote system state on or off. any body help me to find remote system on or off state using java.net package. no need to use RMI concepts.

ping usually works, but again, some systems may have it turned off. Some systems (like Unix) also provide an 'isalive' command, but it's probably based around ping.

Has anybody had an issue with System State Backups on a Dell PowerEdge R510 Server running Server 2008 R2?

Hi,
We have recently had issues running system state backups on our 2008 R2 Domain Controllers.  They are running on Dell PowerEdge R510 Physical Hardware. Whenever you initiate a system state backup, the Domain Controller becomes unresponsive
forcing us to physically reboot it.   Nothing in the Event logs or the Dell Open Management Hardware Software indicates issues with Phyiscal disks but we can always replicate the issue by starting the system state backup.
The system state backup is initialted as a batch file that runs as a scheduled task.   the commands run are as follows:
WBADMIN START SYSTEMSTATEBACKUP -backupTarget:[drive letter] -quiet
We have 4 Domain Controllers with identical disk configurations. When the DCs were setup I confirmed the system state backups were working but the issue started occuring sometime in Dec 2014. We are going to run the Dell Hardware Update Utility
to update the RAID, BIOS, Firmware updates but Has anyone experienced a similar issue that may have been triggerd by a Microsoft Patch?
Thanks,
Kevin C.
