Re: Lightning Damage

Hi, if this is lightning damage then unfortunately you are up for a new router and pray that your mother board has survived.
To check motherboard, open case use a torch and study the capacitors in side. these are round objects that stand out from the board in rows of up to 6. if any of them show signs of bulging out the top or bottom then your mother board is also most certainly damaged and will need replacing.

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

  2. On the Registry menu, click Export Registry File, type backup-key in the File name box, and then click Save.

  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.

Unable to connect to DHCP server. getting 169.254 ip Have already tried the following: unplug/ reset reboot router; ipconfig /release /renew; Run MBAM Version 1.43; System restore to a date when connection...

Whew! Awesome troubleshooting work there.

When it's configured for DHCP, go to the Internet Protocol (TCP/IP) Properties and hit Advanced to bring up the "Advanced TCP/IP Properties" dialog.
Under the IP Settings tab, the top panel should be "IP addresses" and should have "DHCP Enabled" as the only entry, and the default gateway should be blank.

If both of those are correct, then I have one other question for you:

When you manually set an IP, are you able to use the network? If so, are you able to ping the DHCP server's address?

If so, then my guess would be that the DHCP server has a stale record for your Dell's MAC address.

Post back with the "Add Comment" button here and we'll get it working for you.

Wireless connection

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

Reboot the machine

I have a dlink - dir-301 wireless router and i can connect, i can see my network but i can connect, even though all correct lights are on the router and i have the correct password

1) Check and test your firewall. Your firewall, especially if its a software firewall like ZoneAlarm, Black Ice, Norton Firewall or something else could be blocking the connection. Disable your firewall and test the connection.

2) Check your IP address

3) Reset your TCP/IP stack by downloading and running WinsockXPFix.exe a Visual Basic program designed to fix corrupted TCP/IP issues, host file problems and a variety of other connectivity issues.

I have a zyxel p66ohw router connected to my pc via an ethernet card, everything is fine untill my son logs on with his playstation 3, or my wife logs on with her laptop then i cant connect everytime i try...

Make sure that your TCP/IP properties are set to "Obtain an IP address automatically". If you still cannot connect after you change that, and after waiting for a couple of minutes, then open a command prompt and type "IPCONFIG". Make a note of the address at "Default Gateway . . . . . . . . . :" That's the address you need to go to to access the modem's settings..You'll need an ID and password. These would be in the modem's manual.
---to find tcp/ip properties---
It depends from PC to PC, but, try this:
Start (Bottom left of your screen)
Network Connections
Local Area Connection
Internet Protocol TCP/IP

That's how it is on my PC.
