WRT54G....Can I set DHCP to use the router for DNS instead of external DNS?

Hi folks. I cant' get my router to have DHCP tell my PCs that the router should be the DNS server instead of the external servers it is using. I am using Comcast Cable internet. It sets the external DNS servers for every PC that connects to it and I have problems finding my PCs on my network by NetBIOS name because the external DNS servers obviously don't store my local PCs. How can I set the router up to set DHCP to use the router for DNS?

If you cannot set the DNS server in the configuration page for the DHCP server in your router then your router does not support this.
This won't solve your problem though. The DNS server on the router is a simply forwarder. It simply forwards the DNS requests from your computer to the ISP's DNS servers. The DNS server does not accept dynamic updates to a private zone inside your LAN. And DNS is pretty much unrelated to the standard windows workgroup browsing which does the actual name resolution inside your LAN. That name resolution even works without a router inside your network. Basically all windows computers in your network periodically broadcast their name to the network. One windows computers is elected "master browser" which collects all these names and provides the name resolution service for all computers in the workgroup.
If this does not work it is most likely a windows configuration problem. It could be a software firewall on the computers which blocks traffic. It could be that the computers are not setup for file/printer sharing and thus have the computer browser disabled. It could be that your computers have a WINS server configured which does not exist. There are probably more causes. The better source to ask this question would probably a Microsoft support group. They deal with these kinds of issues more often and maybe a MVP may be able to point you into the right direction or give some links to step-by-step instructions...

  • Can not port forward on WRT54GS v6 "You cannot use the router IP"

    Hello, I'm trying to open a port number, but when I try to use my router's IP, the following message appears
     "You cannot use the router IP, network, or broadband address"
    [IMG]http://i45.tinypic.com/107qond.jpg[/IMG]
    My ADSL was working as a NAT behind a NAT connection, so I had to change my Local IP Address to 192.168.2.1.
    Router: WRT54GS v6 firmware 1.52.8 (latest)  -  Bellsouth router: Westell 6100
    Microsoft Windows [Version 6.1.7600]
    Ethernet adapter Local Area Connection:
       Connection-specific DNS Suffix  . : launchmodem.com
       Link-local IPv6 Address . . . . . : fe80::40a9:a76e:61b3:6435%11
       IPv4 Address. . . . . . . . . . . : 192.168.2.100
       Subnet Mask . . . . . . . . . . . : 255.255.255.0
       Default Gateway . . . . . . . . . : 192.168.2.1
    So, please help me, how can I open ports on my router? =[
    PS: I tried to use 192.168.2.100, and even though it lets me use it, it still seems not to open that port... my IP is dynamic.

    Generally: NAT behind NAT is a bad idea. There is usually no need for double NAT. Either configure the ADSL router as bridge and use the WRT for your internet connection or set up the WRT as simple access point behind the ADSL router.
    It's also unclear to me what is working or not. First I thought you can't set up forwarding at all because you get that error message. Then, in your PS you write you tried to use 192.168.2.100 and that seemed to be possible. The IP address to forward to must be the IP address of the computer to which you want to forward. Thus 192.168.2.100 is exactly the IP address you have to set up. Does this work or not?
    Also remember: with double NAT you must set up two forwardings: first on the ADSL router then on the WRT. Port forwarding is necessary to allow incoming traffic through NAT. All incoming traffic arrives on the ADSL router. Thus setting up port forwarding on the WRT only won't do a thing.
    It's also not recommend to use dynamic IPs for forwarding destinations. Dynamic IP addresses may change over time and that requires you to adjust forwardings accordingly. It's better to reserve fixed IP addresses (if your WRT supports this) or set a static IP address on the computer outside the DHCP address pool.

  • I recently bought a new macbook pro and set it up using the migration assistant and my mac mini.  I can't get the text message forwarding feature to work with both computers.

    I recently bought a new macbook pro and set it up using the migration assistant from my mac mini.  I can't get the text message forwarding feature to work with both computers.  It keeps saying that I only have 2 devices setup, my iPad and my macbook pro.  When I mess with the setting on my mac mini, it goes from saying that that is one of the devices to my macbook pro being the 2nd device.  I think that something happened as a result of my using the migration assistant and now it thinks that my macbook pro and my mac mini are one and the same computer.  Any ideas?

    Thanks, Sig.
    The old computer is a 2.6 Ghz Intel Core 2 Duo
    The new one is a 2.3 GHz intel core i7
    In going over this, thanks to "tallking it out" with you, I did discover the Text Edit problem.  Because I've still been unable to get the new computer text size (fonts or whatever) to match the old computer, I did not notice that the curser is now different--the line midway down the curser has to be placed on the line I am working upon, otherwise the edits go elsewhere on the page.  Now, with a bit of difficulty, I am able to get Text Edit to work correctly.
    If you have any ideas as to why my menu bar and Text Edit type are still so slow, I'd love to have them. 
    (I went through the process you suggested earlier, re my Trackpad preferences, and found no improvement.)

  • Can I set up ipad in the and use in uk (uk bought)

    I bought my girlfriend an iPad mini for her 18th birthday in the uk, we are in vagas, America for when she will open the gift. Can she set it up in the US and still be able to then take it home to the uk and use it? Thanks

    Yes, but she should configure it with her UK information, Apple ID, iTunes account, email, etc. That's all done over the Internet so she only needs a wireless connection to do it. It's all prompted for at the setup when she first turns it on. Read the instructions first.

  • Can my husband and I use the same e-mail address/AppleID for our 2 phones, our iMac, and our Macbook?

    Can my husband and I use the same e-mail address/AppleID for our 2 phones, our iMac, and our Macbook?
    We share an e-mail account and would like to use the same e-mail address for both our phones, as well as our computers at home. Is this possible?
    We both have itunes and apple ID's of our own right now, but since getting married, we are deleting these e-mail accounts and sharing one. How can we make this work?

    You may use the same Apple ID for iTunes and App Store purchases, but using different iCloud Apple IDs is recommended.
    If you use the same iCloud account on your iPhones it will sync all of your contacts, reminders, and notes automatically and it could be a pain. I don't know exactly how you would want to have the iCloud accounts set up on the Macs, because I don't know exactly how you use them. (I am assuming you share?). But you can do whatever you like, you can even keep the same iCloud accounts, etc but you may want to disable the syncing of certain items, because reminders for ones phone popping up on the others automatically would probably get annoying, but that is just me.

  • My wife decided to set up her iPhone on my account and now everything is comingled.  I want to set up an iTunes account for just me. Do I have to set that up on a computer or can I set it up on the iPhone?

    My wife decided to set up her iPhone on my account and now everything is comingled.  I want to set up an iTunes account for just me. Do I have to set that up on a computer or can I set it up on the iPhone?

    iTunes will need to be set up on your computer however you can set up a new Apple ID to use for your iPhone. Really all you need to do is Assign a new Apple ID to your iCloud account.
    Follow the link to create a new Apple ID: https://appleid.apple.com/cgi-bin/WebObjects/MyAppleId.woa/
    After you do that, on the device you want to assign a new iCloud account go: Settings > iCloud > Delete Account and then sign in with the new Apple ID.
    NOTE: This does not effect iTunes, all of your devices can continue to use one shared iTunes account under your original Apple ID for downloading apps and backups. This simply gives iCloud a place to sync the individual devices information and will stop iCloud form merging all the information, such as contacts, with all of your devices.

    Can I airplay a movie from safari on my MacBook to Apple TV and still use the computer for something else at the same time?

    Hi frogjt,
    Welcome to the Apple Support Communities!
    Great question! You can absolutely do this in OS X 10.9. The attached article explains how the process of using AirPlay with Apple TV to create a second display. Also, towards the bottom of the article there are instructions on how to set your Displays preferences on the computer to make sure the TV and MacBook Pro displays are set up the way you want them to be.

  • Can new PWA views be created whereby a filter can be set and associate to the view by default? (Project Server 2013 ONLINE)

    My main question is: Can new PWA views be created whereby a filter for that view can be set, and associate to the view by default? (Project Server 2013 ONLINE)? and can I have a filter set to filter on person logged on to...
    In previous versions of Project Server, when CREATING a PWA view, we were able to apply/ define a filter for that view.  Does not seem like it is the case in Project Server 2013 Online.  And if I remember, we could also use the URL Guid_view_id. 
    Please confirm; and / or tell me how-to.
    What I was hoping to do is the following... Given that our standard that we have adopted for reporting time is 'My Timesheets' (fyi, Single Mode Entry=ON), we have some resources who have others who do it on their behalf via 'My Tasks' (ie., accomplished
    by using the 'Assignment Owner' field, accordingly).  Therefore, when entering time on someone else's behalf within 'My Tasks', we like to present the user that is logged in only the tasks that they are are assigned to update on others' behlaf.
    I know that there is another more elegant approach to doing this which may be to use the Delegation feature. But since we are trying to stick to Sharepoint Security mode for now, this is not an option for the time being.
    Any help appreciated would be greatly appreciated.
    \Spiro Theopoulos PMP, MCITP. Montreal, QC (Canada)

    Hi Spiro,
    1- You still can define in Project Online a filter in the view settings, it is located just above the category setting. Here is a screenshot of the summary project center view:
    2- The view GUID is not anymore in the URL, since the URL triggers an action only on the webpart and not on the whole page. I agree this is annoying since it was great to send a URL with a specific view.
    3- Concerning the access to my timesheet versus my task, I'm not sure to get a full understanding but on a general way, it is much more easy to deal with those situation using categories which you cannot do with the SP permission mode.
    Hope this helps,

  • HP Laserjet p2035n Can't set DHCP

    Hello I have a HP Laserjet p2035n connected via a switch to a LAN. The printer had a static IP address configured, and handled print jobs from connected PCs with no problem till yesterday.
    The printer stopped responding to print jobs sent accross the LAN. Also, I was unable to access the web admin interface for the printer. I decided to reset it to factory settings and reconfigure it from scratch. I powered off the printer and held down both the GO button and the CANCEL button while powering the printer back on. The indicators all flashed in unison signalling that the printer had been reset.
    When I printed a configuration page however, it indicated that the printer was still in manual IP configuration mode with an IP of 0.0.0.0 meaning that it would not pull a temporary IP from my DHCP server. Sure enough, I was unable to access the printer web admin interface after the factory reset.
    I tried upgrading the firmware, I tried installing the HP software on my laptop to see if there was a setup programme that would reconfigure the printer ... I tried connecting directly via USB and successfully printed a few pages.
    Can someone tell me if there is a way to  reset the network connection mode of the printer back to DHCP, perhaps using the buttons on the printer, or some tool that I can download.
    Thank you for any help that you could offer.
    ELMKD

    Hello:
    Thank you for your response. I resolved the problem.
    A static IP was reserved for the printer by my DHCP server.
    The printer experienced a duplicate IP error on the LAN which was not indicated on the configuration page.
    The printer was returned to factory default, but could not complete the initialization process (it is unclear why).
    Network Information showed the following:
    Status = Initializing
    Host Name = ...
    IPv4 Address = 0.0.0.0
    IP Subnet Mask = 0.0.0.0
    IP Default Gateway = 0.0.0.0
    IP Configured By = Manual
    etc...
    This meant that the EWS could not be accessed, and the printer would not pull a new IP via DHCP.
    Solution
    1. Return printer to factory default by powering off, and holding down both CANCEL and GO buttons while powering on.
    2. Ensure that there are no IP address conflicts on the network affecting the printer.
    3. You may have to connect the printer to a separate subnet to get it to fully initialize and pull a temporary IP via DHCP
    4.  Print a configuration page by holding down the GO button for 5 seconds and verify that you have a new IP
    5.  Access the printer web admin page via the new IP and reconfigure the printer as needed. Static IP etc.
    I hope that this helps someone else who might be confounded by this problem.

  • Setting password expiry using the SDK

    Without using the iDS console, meaning just by using the SDK, could I set the period for password expiry?
    Since the userPassword is a multi-value attribute, how can I differentiate between which is the password for signing-onto the server and which are passwords for other applications?

    If you mean to configure the password policy using the SDK, a Modify operation for the base object "cn=config" and replacing the value of "PasswordMaxAge" attribute will work.
    If you intend to set a specific expiration time for a specific user, you should not do this and let the server set the expiration time based on the configured password ploicy.
    For more information on the password policy configuration, you can refer to the Administration Guide.
    Also, although userPassword is multivalued, the pasword policy as currently defined in the Directory server suppose that the userPassword attribute contains only 1 value. If the password contains more than 1 value, the result of the password policy is undefined.
    And there is no way to differentiate between passwords.

    how to make TC to be a new external
    click here for instructions. once set up,  time machine may ask you if you want to use the TC for backups but you can decline.
    the TC will show up in the finder under the shared header. click on the icon and your computer will connect to the TC, when that's done, you will see a folder called Data, which actually is the TC's drive. click on the folder and the TC's drive will mount on your desktop.
    now you can drag & drop files to it like with any ordinary external HD.
    can the files through by wifi ?
    yes.

    I have bookmarked several sites which require a password. Firefox remembers the password ok. When I click on the bookmark, a page comes up with the password request, already filled in, and I have to click again to open the page I'm after.
    Can I set it so that the page opens automatically, without having to click on the 'submit' button?

    You could try the Secure Login add-on - https://addons.mozilla.org/en-US/firefox/addon/4429/
    The add-on provides enhancements to the login process, if you have used Opera it is similar to the Opera Wand function.
    One feature of the add-on is to provide direct login to any site from the bookmarks by using the "Secure Login Bookmarks" option.
