Can not activate the discovery network in Vista

I just reinstalled Vista on a laptop and went to connect to a wireless network that previously worked before the re installation of Vista.  Network discovery was off so I turned on and then you click on confirm and return to the window and it is still off.  So, I can't turn it on.  Any ideas please?

Hello

1. What is the brand and model of the computer?

2. What is the accurate and complete error you get when you try to activate the service?

3. What is the security software installed on the computer?

 

Method 1.

Step.I

Make sure that the following services are enabled on the computer.

(a) click Start and type "services.msc" in the search and click on services and ensure that these services are enabled:

-TCP/IP NetBIOS Helper service

-DNS Client

-Function Discovery Resource Publication

-SSDP Discovery

-UPnP device host

To start the service and set it to automatic, follow these steps:

(b) right click on each of the services listed above and click Properties.

(c) click the general tab, and then, next to startup type, select automatic.

(d) click on apply and then click Start.

Step.II

I suggest that you can exercise SFC scan and check if TI the problem persists. To do this, please see the following article. The SFC/SCANNOW command. analyzes all protected system files and replaces incorrect versions with appropriate Microsoft versions.

For more information how to make SFC / scan, please follow this link: http://support.microsoft.com/kb/929833

Step.III

Try setting your computer unbootable inClean State and check to see if the same problem happens. Setting of the clean boot state system helps determine if third-party applications or startup items are causing the problem.

How to troubleshoot a problem by performing a clean boot in Windows Vista or Windows 7:
http://support.Microsoft.com/kb/929135

Note: After the boot minimum troubleshooting step, follow step 7 in the link provided to return the computer to a Normal startup mode.

Step.IV

The problem can also be caused by your security such as anti-virus program or a firewall of Windows /Defender that can have conflicting parameters as to not not to perform certain tasks. I suggest you temporary disable antivirus and firewall and check the result again. You must activate new security that you was disabled programs.
Disable the antivirus software:
http://Windows.Microsoft.com/en-us/Windows-Vista/disable-antivirus-software

Important note: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you need to disable temporarily to install other software, you must reactivate as soon as you are finished. If you are connected to the Internet or a network, while your antivirus software is disabled, your computer is vulnerable to attacks.

Method 2.

You can update the network drivers and check.

  • Can not activate the WLan on Satellite L350D

    First of all, sorry for my bad English

    I'm having problems with the WIFI, I fail to enable it to connect to a wireless router and be able to connect to the internet

    Computers icon is green: if I choose: to built a connection or net and then I choose to connect to a router or wireless access point, I hit 'next' and then he said: "hardware detection and configuration of the net ' and then he said 'Windows don't detect any material NET Wireless' and he said ' to create a net wireless and flash configuration keeps in a usb unit»

    In the blue icon of a computer and like a ball behind: there is a screen called CONFIGFREE.

    If I press the 'radar' it says "this device net wireless is disabled." Enable the device"and if I touch" doctor conectivity, in ' "rolling / wan wireles ' State of the switch is enabled and the firewall is disabled.»

    But then, in the design, although it has two arrows. Blue disconnects and if I change the profile, it is said that the wire is not available and the realtek fast ethernet is available.

    Hello

    Your description is a bit confusing.
    So here are my Tips how to connect the laptop for WiFi using the Vista operating system.

    First check if your WiFi is turned on. You must use the key FN + F8 to go tot eh card WLan and then turn on the WLan switch on the side of the laptop.

    According to your WiFi (Atheros or Intel) card I advise to use a WLan configuration as Atheros Client Utility or Intel ProSet Utility tool.

    You can use these tools to configure WLan. I use one of these tools and I can connect and configure the WiFi network very easily.

    If you want to use the Vista WLan own configuration options, can access the network locations and right click on the WiFi connection.
    Choose then rebuilt Waln connection or something like that.
    Then choose your WLan which has been configured on the router WLan and put the right encryption settings and you should be able to connect to you wirelessly.

  • can not find the wireless network

    Hello

    I hope someone can help. Today, I got a new installed wireless router. Until now my main and most recent computer can connect to the internet fine (so I know this isn't a network problem), but my old computer does not find the network when scherching of available networks, it may pick up other networks and communicate with them simply not my own. It is the first time that I am trying to connect to this wireless computer.

    The computer is a HP pavilion t770.uk Windows xp sp3.

    You need to replace the network adapter. The current NIC is older than the specification of N, so it can not communicate with this Protocol.

    You can try to configure your router and the new pc to use b, if they allow.

  • After update to 5.0.15 server, can not activate the OD service and the Profile Manager

    Hi, I have recently updated my Server 5.0.15 under El capitan 10.11.3.

    After that, Service OD and the Profile Manager can be activated server GUI.

    Of course, all users on my network are missing from the list of users; just local users remain.

    Reason: cannot be connected to the node 127.0.0.1

    How can I recreate an OD without use of app server?

    Thank you.

    P. S.

    Of course, even in the local server translates users preferences pane not connected.

    Many Open Directory problems can be solved by taking the following measures. Please test after each of them that you have not already taken it and back up the data before making any changes.

    1. the OD captain must have a static IP address on the local network, not a dynamic address. It must not be connected to the same network with more than one interface; for example, Ethernet and Wi - Fi.

    2. you must have a working DNS serviceand the host name of the server must match the FQDN name. To confirm, select the server by its name in the sidebar of the window of the server application, and then select the Preview tab click the button change on the host name line. The access that your sheet of server, the domain name must be selected. Change the host name, if necessary. The server must have at least three levels (for example, "server.yourdomain.com") name, and the name must not be in the top-level ".local" domain, which is reserved for Hello.

    3. the main DNS server used by the server must be itself, unless you use another internal DNS server. The only DNS server on the clients should be internal, they should get from the DHCP server, as appropriate.

    4. If you have accounts with basic network directories, make sure that the URLS are correct in the user settings. A return status of 45 from the demon authorizationhost in the newspaper may mean that the URL for the installation directory was not being updated after a change in the host name or the file sharing protocol (AFP, SMB, or vice versa.) If the server and the clients run all OS X 10.10 or later, directories should be shared using SMB instead of AFP.

    5. follow these instructions to recreate the Kerberos configuration on the server.

    6. If you use authenticated connection, check the validity of the certificate of the master. The common name must match the host name and domain name. Unselection and then reselect the certificate in.app was reported to have an effect in some cases. Otherwise, delete all certificates and create new ones.

    In the case of a self-signed certificate, create a trust profile in the Profile Manager and deploy it to the customers. On the server, you may need to create the folder

    /etc/openldap/certs

    and place a copy of the certificate of the server, for example:

    /etc/openldap/certs/server-name

    Also add a directive to the file

    /etc/openldap/ldap.conf

    of the form

    TLS_CACERT /etc/openldap/certs/server-name

    7 remove the link, then to connect customers in the preferences users and groups window. Use the FQDN of the master name.

    8 restart the master and clients.

    9. do not connect you to the server with the account of the user of a network.

    10 turn off the internal firewall in use, including third-party "security" software

    11. If you have created replica servers, remove them.

    12. If OD has recently stopped working while it was working before, you can be able to restore automatic backup in/var/db/backups, or a snapshot of the time of this backup Machine.

    13. If there is slapd errors in the log, try the following steps.

    Disable the Open Directory in the server application.

    Enter in a shell:

    cd /var/db/openldap
    sudo -s
    db_recover -c -h authdata
    db_recover -c -h openldap-data

    Turn on Open Directory.

    14 reset database password strategy:

    sudo pwpolicy -clearaccountpolicies

    15. as a last resort, export all users od. In the Open Directory of the server pane, delete the OD server. In some cases, you may need to use the shell to remove the server. Then recreate it and import the users. Make sure that the UID is in the range 1001 +.

  • I installed Windows XP Home Edition. Can not find the wireless network drive

    I installed Windows XP Home Edition on my spare PC.  Now I have wireless network card in the computer and problems to find the drivers for it, and I don't know what brand it is, so I know it's kind of makes it harder too.  Then I also have to start the computer, but if I press F1, the computer starts well

    I was just wondering how can I get rid of this?

    Disable all devices that can connect to your router (wired or wireless)...

    • PCs
    • Laptops
    • Tablets
    • Smartphones
    • Smart TV
    • Printers
    • Networked storage
    • Another thing that I have not mentioned above!

    Put on your router and wait for the normal light distribution. Then turn on all devices.

    I hope that your ip address conflict went away. Generally ip conflicts can happen when the router is running again without doing the same with all devices later.

    If you have even an ip address conflict, it is possible that you forgot something above or can someone use your router without your knowledge.

    Your router's wireless network is secure? Ideally with WPA2 encryption?

    My printer HP Officejet 6100 has recently lost its eprint connection and would not reconnect.  I asked for help and told

    The restarted printer and now the printer cannot be found or will not connect to my

    I tried to power on the printer, the modem and the router so that it would reset but the printer would not still find or connect to the wireless network.  The little blue light on the printer for wireless connection just continues to blink.

    Because it connects to the wireless network I can not go back in the server web part to cancel the IP address manually and other changes.

    Is there a way I can reset this?  Or get my printer to connect to the wireless network.
