Hello,

In that case, i suggest you to remove the hard drive and connect it to other computer which has a potent antivirus and scan. You can use the online scan here: http://www.precisesecurity.com/antivirus/online-scan.htm

But most likely if the system is infected with virus, virus can be deleted but the system is slower ..guess reformatting and and windows installation is the best way.

pls do not rate me if my solution not solve the issue and you need more further information. but if is invaluable solution rate me fixya.

best regards, melnavz

Dial up connection ends in error code 720, can't connect to the internet. Using a back-up pc that is terribly slow. would like to fix pc.


Error 720 - the connection attempt failed because your computer and the remote computer could not agree on PPP control protocol.

To resolve this issue, uninstall the TCP/IP protocol, remove the second WAN Miniport IP device, and then reinstall the TCP/IP protocol. To do so, follow these steps:
  1. Uninstall the TCP/IP protocol. To do so:
    1. In Control Panel, double-click Network and Dial-up Connections, right-click Local Area Connection, and then click Properties.
    2. Under Components checked are used by this connection, click Internet Protocol (TCP/IP), and then click Uninstall.
    3. Follow the on-screen instructions to uninstall TCP/IP.
    4. Restart the computer when prompted, but click No if you are prompted to allow Windows to enable a protocol.
  2. Right-click My Computer, and then click Properties.
  3. Click the Hardware tab, and then click Device Manager.
  4. On the View menu, click Show hidden devices.
  5. Under Network adapters, there should be no WAN Miniport IP devices. If a WAN Miniport IP device is listed, continue to the following step. If no WAN Miniport IP device is listed, go directly to step 16.
  6. Click Start, click Run, type regedit in the Open box, and then click OK.

  1. Locate the following registry subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318}
  2. On the Registry menu, click Export Registry File, type backup-key in the File name box, and then click Save.

    Note You can restore the changes that you make to this registry key. To do so, double-click the backup-key.reg file that you saved.
  3. Click each of the registry subkeys under this key, and then view the Data column of the DriverDesc value to determine which of the subkeys corresponds to WAN Miniport (IP). For example, the 0005 subkey.
  4. Right-click the subkey whose DriverDesc value data is WAN Miniport (IP) (for example, right-click 0005), and then click Delete. Click Yes to confirm that you want to delete the key.
  5. Quit Registry Editor.
  6. Right-click My Computer, and then click Properties.
  7. Click the Hardware tab, and then click Device Manager.
  8. On the View menu, click Show hidden devices.
  9. Under Network adapters, right-click WAN Miniport (IP) and then click Uninstall. Click OK to confirm that you want to remove this device.
  10. Reinstall the TCP/IP protocol. To do so:
    1. In Control Panel, double-click Network and Dial-up Connections, right-click Local Area Connection, and then click Properties.
    2. Click Install.
    3. In the Select Network Component Type dialog box, click Protocol, and then click Add.
    4. Under Network Protocol, click Internet Protocol (TCP/IP), and then click OK.
    5. When the protocol is installed, click Close.
  11. Reset the modem by turning the power off and then on, or for an internal modem, restart the computer.
  12. Test your Internet connectivity.

Windows File Sharing And The Dangers Of NetBIOS


NetBIOS is a Windows File and Print Sharing protocol, and it uses TCP/UDP ports 135, 137,138, and 139.

* TCP/135 - RPC: This port is potentially quite dangerous. Remote Procedure Calls are requests from one machine to another for service. The RPC service acts as something of a facilitator, or go-between, between the client making the request and the machine being asked for service, i.e. a request is made to this "end-point mapper service" and then a port is allocated dynamically to the service being requested. This is similar to the RPC functionality found in the Unix world, and although it's not technically a "file sharing" port, it ties heavily into Windows networking in general.

* UDP/137 - NetBIOS Name Service: This port is used to attain name resolution for NetBIOS. Think of it as NetBIOS's version of DNS or ARP. It's simply a way to use something you have, make a query, and get something you want in return. For NetBIOS it's from a NetBIOS name to an IP, for DNS it's a DNS name to IP, and for ARP it's from IP to hardware address.

* UDP/138 - NetBIOS Datagram Service: This port primarily allows the SMB browser service to populate the browse lists seen when using "Network Neighborhood".

* TCP/139 - NetBIOS Session Service: This is perhaps the most known Windows port of all, as it is used to transfer files over TCP. This is both the port that NULL Sessions are established over and the port that file and printer sharing takes place on. If you are considering restricting access to ports on your Windows machine, this one needs to be on the top of the list.

NOTE: By disabling NetBIOS, all existing file shares must be shared using the IP address, rather than the NetBIOS Name, or else the share won't work.


How to disable NetBIOS in Windows 2000:

  1. open Windows Explorer
  2. Right click on My Network places and select properties
  3. Click Internet protocol TCP/IP and select properties
  4. Click on Advanced and then WINS
  5. Select Disable NetBIOS over TCP/IP and click ok
  6. Restart your computer
  7. If Windows displays "This connection has an empty ... " message, ignore it and click ok
How to disable NetBIOS in Windows 95/98/ME

Start->Settings->Control Panel. Double click in Internet Options.

On the Connections tab, click on Never Dial a Connection. While you're there, click on LAN settings. Automatically detect settings should be checked, but normally nothing else should be checked.

If this doesn't help, you may need to rebuild the stack:
Start, Run, CMD to open a command prompt.

Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

Reset TCP/IP stack to installation defaults. netsh int ip reset reset.log

Services You Can Disable


There are quite a few services you can disable from starting automatically.
This would be to speed up your boot time and free resources.
They are only suggestions so I suggestion you read the description of each one when you run Services
and that you turn them off one at a time.

Some possibilities are:
  • Alerter - Sends alert messages to specified users that are connected to the server computer.
  • Application Management - Allows software to tap directly into the Add/Remove Programs feature via the Windows Installer technology.
  • Background Intelligent Transfer Service - The Background Intelligent Transfer service is used by programs (such as Windows AutoUpdate) to download files by using spare bandwidth.
  • Clipbook - ClipBook permits you to cut and paste text and graphics over the network.
  • Error Reporting Service - Allows applications to send error reports to Microsoft in the event of an application fault.
  • Fast User Switching - Windows XP allows users to switch quickly between accounts, without requiring them to log off.
  • Help and Support - Allows the XP Built-in Help and Support Center to run.

  • IP SEC - Manages IP security policy and starts the ISAKMP/Oakley (IKE) and the IP security driver. If you are not on a domain, you likely don't need this running.
  • Messenger - Transmits net send and Alerter service messages between clients and servers. This is how a lot of pop-up windows start appearing on your desktop.
  • Net Logon - Supports pass-through authentication of account logon events for computers in a domain. If you are not on a domain, you don't need this running
  • Network DDE - Provides network transport and security for Dynamic Data Exchange (DDE) for programs running on the same computer or on different computers.
  • NT LM Security Support Provider - Provides security to remote procedure call (RPC) programs that use transports other than named pipes.
  • Performance Logs and Alerts - Collects performance data from local or remote computers based on preconfigured schedule parameters, then writes the data to a log or triggers an alert. If you don't need to monitor your performance logs, then you don't need this service.
  • Portable Media Serial Number - Retrieves the serial number of any portable music player connected to your computer
  • QOS RSVP - Provides network signaling and local traffic control setup functionality for QoS-aware programs and control applets.
  • Remote Desktop Help Session Manager - Manages and controls Remote Assistance. If you are not using Remote Desktop you don't need this service.

Computer will not recognize drivers for ethernet card


Was this all working just fine prior to reinstalling the system on the computer. I want to first rule out any hardware connection problem. When you check the ethernet adaptor in the device manager, does any punctuation mark appear next to it to indicate a driver problem? if not, your problem is not driver -related, but rather settings. If the LAN connection appears in the manage connections or the connection wizard, you may only need to enter the correct settings to make this work. Make sure TCP/IP is enabled for the device, and that DHCP is enabled in the TCP/IP settings. The exception to this is if the modem does not assign an address by DHCP but is instead set for only a static address. If that be the case, you will need to enter a static IP address in the TCP/IP settings. In that case, look for a number on the modem in a xxx.xxx.x format, enter the number in the TCP/IP static IP address but adding 10. If the address is static, you will also need to enter a default gateway, which your ISP should have provided to you, along with the static address

If you find my suggestions to be helpful, please share with us some details so that others may benefit from knowing the whole story. Thank you!.
