Intermittent Loss of Network Connection Vista
Two of my Vista Desktops are connected with SMC Barricade G router via Ethernet Wire. Don’t know what went wrong, both of these PCs are losing connections randomly. They loose the connections and restore it automatically after sometimes. My ipconfig /all show the following result:

And when I checked the Event Viewer logs, it shows the following entries:
- Event ID 27; Intel(R) PRO/1000 PM Network Connection Link has been disconnected.
- Event ID 2505; The server could not bind to the transport \Device\NetBT_Tcpip_{737A72A7-5D80-4E6B-B2B4-1F599399F2E5} because another computer on the network has the same name. The server could not start.
- Event ID 4321; The name "NEWTECHFX530 :20" could not be registered on the interface with IP address 0.0.0.0. The computer with the IP address 192.168.2.103 did not allow the name to be claimed by this computer.
- Event ID 1003;Your computer was not able to renew its address from the network (from the DHCP Server) for the Network Card with network address 0019D16D7512. The following error occurred:
- The operation was canceled by the user.. Your computer will continue to try and obtain an address on its own from the network address (DHCP) server.
Any help will be appreciated.
Re: Intermittent Loss of Network Connection Vista
I think there would be duplicate IP and name. Can you just check the DHCP for the same. Make sure there is no duplicate IP addresses. .
Re: Intermittent Loss of Network Connection Vista
Thank you very much for your reply prash_mate but being a newbie in network stuffs, I don’t know how to check it. Can you please tell me how can I check the DHCP for duplicate IP addresses or names? Thanks again.
Re: Intermittent Loss of Network Connection Vista
You can check it in your Routers settings page. Just use web utility and access SMC Barricade G router as DHCP server.
Re: Intermittent Loss of Network Connection Vista
All right, I checked the DHCP Client Log as you suggested and found that there are 3 computers on the network and each of them have their unique IP address, unique MAC address, and a unique name. Now what?
