Troubleshooting Basic Connectivity

Troubleshooting Basic Connectivity

1. Ensure that all computers have the same protocol installed. This should be TCP/IP normally.
2. The IP addresses on the same network adapter for each computer should be in the same range.
3.
Verify that the ICF doesn't block the File and Printer Sharing.
4.
Use the ping IP or computername to test connectivity between two computers on the network. If you can ping IP but not computername, this is name resolution issue.
5. if you can ping ip and computername, but you can't map any network drive, use net view \\remotecomputer to find out the problem. If you get error 5, this is permission issue. If you get error 51, make sure that you have enabled file and printer sharing and have some folders to be shared. If you get error 53, this is name resolution issue.
6.
All network access to a W2K/XP computer in a workgroup can use the Guest account without creating a username for other computer logon. So, make sure that the Guest account is set up for network access.
7. Virus - No transportation error.

Can't connect to shared resources on one of  networking computers

Symptoms: you keep receiving the following  message from My Network Places on one of three computers: "The list of servers for this workgroup is not currently available." when trying to access the shared folders. Also the shared drives shows red x. The internet access work fine.

Resolutions: 1) The Internet Connection Firewall (ICF) should not be enabled on the adapters that you use to connect the computers to the home network. If ICF is enabled on these adapters, you cannot connect to shared resources on other computers in the network.

Access permission issue.

When W2K/XP doesn't  recognize the user who wants to access its shared disks or printers, you may see the below symptoms.

1. When win9x tries to access a w2k/xp computer shared folder, the IPC$ prompt. No password will be accepted. Resolution: you need to create the user account on w2k/xp for win98 logon.
2. When W2K tries to access a w2k/xp computer shared folder, Enter Network Password screen with Connect As and Password prompt. Resolution: type a username and password were created on the w2k/xp, you should be able to access the shared folders. Or create the user account on w2k/xp for remote computer logon.
3. When xp tries to access a w2k/xp computer shared folder, Connect to computername screen with Username and Password prompt. Resolution: type a username and password were created on the w2k/xp, you should be able to access the shared folders. Or create the user account on w2k/xp for remote computer logon.

Any users can access to my shared folders even they don't have user accounts on my computer

Symptom: If this is domain network and the shared folders are assigned permission to everyone, any one logon the domain can access to your computer, even you logon locally. However, if some one logon locally (no domain) on a remote computer, he/she should not be able to access to your shared folders.

Resolution: remove everyone from the security of the folders and add user accounts you want to access to your computer.

Can't ping another computer because of the ICF

Sometimes, XP's built-in Firewall may enable after running network setup wizard on LAN connections. You can't ping or access the XP computer. To disable the XP firewall on the connection, go to the properties of the Connections, select Advanced, and deselect the firewall.

Disconnect from the network while process Access data

Symptoms: you are disabled from the network while process an Access data. Ipconfig shows you lost the ip is 169.254.x.x. Rebooting or disable/re-enable NIC may reconnect to the network.

Resolutions: 1. Modify hardware settings.
2. Check the hardware connection.
3. Upgrade the new drive if it is available.

NIC speed can't go up to 100MB

Symptoms: All the same computers connecting to a 10/100 switch work fine except one. If you lower to the speed to 10MB, it works.

Cause: It may be caused by the bad cable.

NIC status displays send only but receive

Cause: Hardware issue such as NIC and switch.

One new computer doesn't talk to a good hub

Symptoms: Just bought a new XP replacing a win98 computer. The XP don't talk to this hub. Other computers use the same cable and hub without problem

Cause: It may be caused by hardware configuration.

XP disconnection issue

1. Try to disable autodisconnection feature first.
2. If disabling autoconnection doesn't fix the problem and other workstations don't have the same issue, check the hardware settings, for example, configure the computer' network cards for half duplex.  Most Hubs don't support full duplex.

For consultants, refer to XP disconnection issue page.

You cannot connect to shared resources on other computers in the network after enable ICF

A: The Internet Connection Firewall (ICF) should not be enabled on the adapters that you use to connect the computers to the home network. If ICF is enabled on these adapters, you cannot connect to shared resources on other computers in the network.
