VMTools Time Sync for member servers Active Directory

Hey guys,.

I was hoping you could help me with a best practice. I did a lot of research on this and there are mixed responses. I'm looking for practical advice. I understand what is needed when a DC AD PDC must be virtualized (registry nosync option, vmtools, etc.). What everyone in the AD domain? They sync using VMTools if your ESX hosts use the same domain controller as an NTP server that would be to use your normal Windows machines? Or just use Windows synchronize the time on your AD VM Member anything? Thank you in advance.

Kind regards

Hello

We have a facility large enough vmware with hundreds of virtual machines in our field. All Member servers synchronize time domain and not by the vmware tools. It worked

no problem for us. The PDC synchronize time from an external time source. time synchronization tools VMware is not used on any of our virtual machines.

That's what I recommend you do.

Best regards

  • search for Windows 'user' Active Directory

    the system will have many users, test records must be saved in the c:\Documents and Settings\\Application Data\Pacing FAT32\

    How can I dynamically determine this path for different users?

    I love the vi "To get the system directory" found in the subpalette of constant file of the file IO palette.  It could be LV2009 only.

    Note that the Application Data folder is hidden by default in win7.  In win7 x 64 the result is "C:\Users\\AppData\Local\Pacing System\" under XP, there "C:\Documents and Settings\Settings\Application Data\Pacing FAT32\"

    Approach to the Yamaeda registry gives me "C:\Users\\AppData\Roaming" questioning "LOCALAPPDATA" or "USERPROFILE" keys are also close to what you want.  If XP does not have these keys, you can also call a command line and environment variable %UserProfile% query.

    @Phil: I had trouble with the "Default data directory" vi before (yesterday actually).  It depends on a setting options in labview.  (Options > paths), I found that when I change this path in the options to use the system directory (uncheck the "use default" checkbox, click the exclamation mark, click on replace, then OK out of options), it gets resets the default restart labview, even if it appears in Labview.ini. This only happens if you use the system-specific path.  It seems to be an old problem:http://forums.ni.com/t5/LabVIEW/Custom-default-data-directory-path-reverts-to-Labview-default/m-p/36...

  • Account for the Services Active Directory permissions

    In the Cisco Unity Message Store Setup Wizard, I have problems with the account for Directory Services.

    I created accounts (for the unit Directory Services) and for the unity Message Store Services and I run the wizard of permissions (usign CUICA).

    However, when I specify the unit Directory Services account, the Configuration Wizard of Cisco Unity Message Store displays an error message indicating that the user doesn't have good Exchange permissions.

    How can that be resolved?

    Thanks in advance

    If you order the Installation of the unit Guide to 4.x with Exchange in the section on creating accounts for the installation\Setting of the Exchange permissions.

    You have to manually delegate the Exchange appropriate for your scenario via Exchange Admin perms.

    The doco details the process better than I could.

    If you already have, I got two check all your accounts and permissions.

    I hope this helps.

  • Snapshots kept long enough for when the Active Directory computer account password has expired - this has been noticed after the restoration of a completed snapshop.  No matter what other configurations out there to address this nuisance?

    I'm curious to know if anyone has implemented a solution to this problem?

    In the AD, a computer account renews his password every 30 days so I think depending on when a snapshot is restored, it may be at a point where the computer account in AD password isn't at the height and which adds a task for the Admin network to readd the computer to the domain.

    So, the longest that a snapshot will remain without any problems is 30 days and the shortest is 1 day.  It depends on the last time the automatic password renewed computer and when the snapshot was taken.

    It's a bit of a pain.

    I'm curious if this is pretty typical and everyone just accepts this manual process?

    Or if some have implemented a solution to work around this problem?

    Thank you!

    There are a few articles Technet (see examples below) that provide information on how to change this behavior. However, keep in mind that it is one updated security related, so consider carefully if we need to change this option in a production environment!

  • Connector for the Active Directory password synchronization

    Friends,
    We have a few questions about the connector for synchronization of Active Directory password:
    1. it is necessary to extend the AD schema when using this connector.
    2. If I have 10 domain controllers and are not synchronized, the literature tells us to install the dll in each domain controller. Is it possible to do this if necessary, to install this dll into a single domain controller?

    Thanks for your help.

    concerning

    Here's what I think:

    *1.* -> No
    * 2-> , I would say no, but it also helps you combat the failover scenario. Suppose that if you had only 1 ms then its failure would not send the password to IOM at all because none of the other DC would have this installed connector

    Thank you

  • Install a new domain on a VM server controller in our Active Directory

    Hello world

    Thank you for your help in advance.

    I would like to put a (with Windows 2003) domain controller in a Windows 2008 box and add the domain controller for the existing Active Directory network. My manager approves it and it will be my advised to work more VMWare work officially.

    Here are some questions that I have and hope you can help answer:

    1.) there will be problems to run a domain controller in a virtual machine environment?

    2.) on the RODC (VM), I can install all services such as DHCP, DNS, WINS? And they will work only with no problem?

    3.) on Windows 2008 Server, which I will install VM Server, that server must be a domain member server?

    (4.) what the backup on the new domain controller? Can I just save the virtual machine files in the folder of BackupExec? Or free tools, I can try?

    5.) I don't think the org will put money on the implementation of a san or vmware structures... According to what I have, have you any tips on this project? Is it a good idea to run the domain controller in the VM environment?

    I thank very you much for your help once again!

    Takusan

    Thank you very much for your info! # 1, you mentioned there are a few things must be aware, can I ask that those who are?

    A few I can think of are:

    (1) supported by Microsoft - backup methods if you want MS support for a problem with the AD, make sure that you use the supported backup methods.

    (2) the time sync - more important still, how you intend to do.  VMware Tools or native Windows utilities.  Discover 1318 KB for more information.

    (3) the safety of encapsulated all the vm files - that is why I recommended given the host on the domain.  It would be more likely to pick up updates of patches, GPO, AV, etc. like this.  Your virtual DC is now portable, and this represents a new security challenge.

    (4) how to avoid snapshots on DCs - what can cause a USN restorations, unsupported directories and General nastiness that should be avoided.

    (5) avoiding the DCs P2V conversions - what is generally not recommended. Their new construction.

    (6) given the requirements of performance - make sure that your host can follow or actually providing the resources to the virtual machine.  You do not want your DC is slow for some reason any.

    There are probably others I'm here leaving as well.  This is why I think that domain controllers does not necessarily make the best pieces for virtualization.  If you take a print server, you will see most of the above concerns disappear.  It can be done with the DC first, but it'll just be a steep learning curve.

  • New authentication active directory on wlc 2504

    Hello

    There is problem with very often a new authentication for servers active directory. Every time only if:

    -loose client wlan/wifi because of the wifi hole or low RSSI

    -output of build for a while customer

    -wlan loose customer due to problem with homelessness (slow, not perfect)

    There is possibility to keep authenticated users? I had hope that options: sleep customer, max session timeout, max idle timeout

    help, but they do not work for me :(

    My access point (2702) are all in a group flexconnect. WLC 2504 (8.1.102.0). My security in WLAN config is:

    Layer2: wpa + wpa2, PSK

    Layer 3: web policy, authentication with LDAP servers + asleep on client

    I always try to improve the radio covers n fast roaming (11 k, r, v) but if someone leaves the area wifi, to do authenticated which is a little annoying...

    Thanks for any advice or an index

    Peter

    You want people who re - attach to your network for to re-authenticate.  It's a good thing.  We do not want people using the old credentials, or expose you to a security breach.

    This behavior is by design - and good.

  • Passwords enable ISE device Administration (ACS) integrating with Active Directory

    I'm working on a standalone application ISE and running into a problem where the password to enable for a device is not shoot properly.  I have the original connection related AD and I policy conditions/results/sets all as they should be working.  My test run is a 2960 S.  I tried to set up ' group aaa authentication enable default Activate ', but the only way I could do a login enabled with which was if the user has configured locally in ISE identity management > identity > users.  Is there something that I missed that tie will enable passwords for a group active directory as I work for the initial logon?

    I see just a mistake with your failure to enable aaa authentication enable. You must specify the Group of Ganymede.

    Right now, I don't have access to my lab with ISE.

    Here's my config for switches used with ACS.

    AAA authentication login GANYMEDE-SRV Group Ganymede + local
    local authentication AAA Console connection
    Group AAA dot1x default authentication RADIUS
    AAA authorization exec GANYMEDE-SRV Group Ganymede + local
    AAA authorization commands 15 GANYMEDE-SRV Group Ganymede + local
    Group AAA authorization network default RADIUS
    AAA accounting exec GANYMEDE-SRV arrhythmic group Ganymede +.
    orders accounting AAA 15 GANYMEDE-SRV arrhythmic group Ganymede +.

    If you give me all out maybe we can understand why your GANYMEDE ISE works do not with the AD. I see no reason except a misconfiguration or another issue.

    Just to go to the mode, you need more aaa authentication command activate by default enable. This activation mode is pushed to the user if he gets the privilege 15. Your problem should be on the profile or politics. With the approval journal, we can see whether or not ISE pushes politics and why?

  • ISE Admin 1.2 access via Active Directory

    Hi Experts,

    Nice day!

    I want to configure my 1.2 ISE to authenticate (for admin) to active directory. I know it's possible, but our ad is not all groups named for admins.

    Is it possible for the ISE 1.2 to configure a local user ID and compare it to the pub for the password of the user ID?

    Thanks for your great help.

    Niks

    Niks,

    I just did this.  First you must have the external configuration of Active Directory as a data source.  Once you do this, click on Administration - Admin Access.

    For the Type of authentication to ensure password database is switched and edit your data source Active Directory (or whatever you named it).

    Then click Administrators - Admin users.  Click Add a user - create an Admin user.  Make sure you check the external box and you will notice that the password field is leaving.  Fill in the appropriate information and then assign them to a group of Directors.

    Once you are done with that you can test the user in you on your ISE session.  You will notice that when you try to log back in you will have the choice of the sources of data used to authenticate the user.  Change the selection in the Active Directory and enter the AD username/password of the newly created account, you should be good to go.

    Make sure that you don't delete or deactivate your original admin account in this process.  (Change the password if you want.)
