LAN, but no Internet

[nikmalsch]

Hello,

Hopefully someone can assist me.
Up until recently I had a perfectly good functioning LAN & internet connection between my 2 PCs (W2K). Now I only have the LAN connection, but can no longer access the internet via LAN from the Client PC ("page cannot be displayed") !!

Present Setup:
Client & Host - W2K + IE6.0 with latest updates
NICs:3COM 3C905B-TX. Connection to internet is via USB to EUMEX (German) ISDN splitter. Internet access software is supplied by ISP (SmartSurfer).
On both LANs I'm using "Client for MS Network, File & Print Sharing, NetBui and TCP/IP".
"Enable Internet Connection Sharing" & "Enable on-demand Dialing" on the internet connection are activated.
Eumex (ISDN) settings are all "automatic".
I had static addresses on both machines with the same SubNet Mask (255.255.255.0) and on the Client I used the Default Gateway address of the Host.
IE connection for the Client is set to "LAN" and I'm using "Automatically detect settings" - nothing else is checked.
IE connection for the Host is set to ??

What works:
The Client & Host can ping their own IP addresses (192.168.0.14/192.168.0.150) and their own Names ("second"/"computer") and those of the other machine.
Pinging 127.0.0.1 and 0.0.0.0 and w3.org all work except the Client cannot ping w3.org.


What I have done to date to attempt to fix this:
I have played with all combinations of addresses including automatic assigned addresses.
Deinstalled NetBui, but this doesn't seem to have any affect - so reinstalled.
I have uninstalled the adapters and reinstalled the latest drivers (3COM Ethernet 10/100 PCI TX NIC (3C905B-TX).
Re-installed IE 6.0 (+ latest updates).
Deinstalled and reinstalled Norton Antivirus & Firewall (also ensured that the other PC is included in the exemption list).
Ran Micorosoft AntiSpyware + XoftSpy + HiJackThis (posted to a forum and deleted suggested files) - found and deleted a few SpyWare bugs.
Ran IspFix to see if the problem was in the Winsock.
Changed NIC cards to see if the problem lies there - no luck.
Lastly, Completely formatted both PCs and reinstalled W2K + Ie6 SP1.

Possible Issues:
I thought the problem could be the Firewalls, but after completly formatting and reinstalling w2k + IE6, I attempted to access the net from the Client WITHOUT and firewalls without any success.
I'm not sure this is normal, but when only the Host is turned on the IP address is different to when both machines are on, i.e IP address is 0.0.0.0
Occassionally Windows Explorer crashes when a file on the other machine is opened (e.g. When I work on the Client PC and open and work on a file from the Host PC).

Event Viewer (CLient="second") tells me:
on starting the PC: "Your computer has automatically configured the IP address for the Network Card with network address 00500437BFD7. The IP address being used is 169.254.236.46."
When I attempt to access the internet: "The master browser has received a server announcement from the computer COMPUTER that believes that it is the master browser for the domain on transport NetBT_Tcpip_{C08BC8C4-6CA0-461E-. The master browser is stopping or an election is being forced. " or
"The browser has forced an election on network \Device\NetBT_Tcpip_{C08BC8C4-6CA0-461E-8C93-20411441A18E} because a master browser was stopped." or
"The browser service has failed to retrieve the backup list too many times on transport \Device\NetBT_Tcpip_{C08BC8C4-6CA0-461E-8C93-20411441A18E}. The backup browser is stopping."

Hey Guys, I know a lot of people have had a similar problem to this before, but this one's got me stumped.

LAN Network has 5 PCs networked to a Dlink DL-624s Wireless Router. 3 computers connecting to Router via pci Wireless adapters using WEP Shared key Ascii 64 bit encryption. PS3 and XBOX 360 connecting to Router via Ethernet cable. PC in question was connecting fine wirelessly until we changed WEP to WPA passkey for the PS3. After this, wireless on only one computer connects to the network and authenticates, but i cannot browse the Internet, whilst all other computers/consoles are connecting without any problems at all. We have tried 3 different cards/USB adapters, and installed them on Windows XP and Linux. Same problem on both. We also reverted back to WEP and put everything back to how it was before, but it still doesnt work. Several reinstallations of Windows and Linux did not fix. Have reset winsock and tcp/ip settigns to default in windows, no luck. Tried both static and dynamic DHCP ip settings, no change. Ipconfig shows correct IP address, correct ESSID, correct Mac Address for my card and for the router. The router config page shows everything correct also. I can ping other computers on the network, and even windows updates is downloading. I just cannot browse (not just IE, but Firefox on both OS's too). PLEASE HELP!!!

Updated firmware on the router?
Latest drivers and windows updates on the machine?
Some times in the wireless forum might help.

Interesting problem, you can receive updates aswell as download/upload however you cannot browse, it may be possible that somehow a proxy was set inside your IE6 and at the time of firefox install when you were prompted to "Import settings" you selected "yes" and it imported the proxy settings to it. Also are you using any time of Antivirus such as Norton Internet Security or Mcafee, as far as the Windows OS goes. Ive had a run in where the features of Mcafee actually "Lockdown" the computer literally, preventing anything from port 80 : which is your HTTP port for browsing from getting in or out.

Edit: Also you might want to check as to how many addresses your current router is willing to release
