unable to display any web site nor ping its DN or IP

[yantisr]

I receive 'The page cannot be displayed' 'The page is currently unavailable. The Web site might be experiencing technical difficulties, or you may need to adjust your browser settings' messages EVERY time I try to contact a web site from IE6SP1. I even installed and tried Mozilla 1.7.1. This is only on my new Toshiba m205-S810 Tablet PC. My Dell Latitude C840 and HP ze5000 laptops have no problem connecting to any web site, secure or otherwise. All are attached via either wireless (802.11b/g) or LAN (Cat5) at my offices (2), at home or in hotels with broadband wireless.

Further, the m205 has no problem connecting to any site via my home Wi-Fi+Direcway LAN or a hotel DSL or cable LAN (e.g. Homestead Suites). And I can authenticate from the m205 to my office W2K server’s AD local domain with no problem, and ping the gateway here, the gateway at the other office, and PCs at the other office. BUT, I cannot ping google.com, or my ISPs DNS servers from the m205 connected to either office LAN, but I CAN from the other two laptops, and I can from the m205 at home or a hotel.

All have identical tcp/ip configurations, excepting unique IP addresses. The DNS server on the W2K server is our Primary, and the ISPs are Secondary and Tertiary. The m205 shows correctly in the forward and reverse lookup tables in the Primary. The m205 uses the Intel Centrino NIC chipsets. The C840 uses Dells mini-PCI internal NIC. And the ze5000 uses either the internal LAN-Express IEEE 802.11 PCI Adapter or a Netgear WG511T 802.11g-108Mbps CardBus NIC. All are configured to use WPA security if available on the AP. The CAT5 NICs are the internal NICs that come with each of the laptops.

I have uninstalled the NIC drivers, rebooted, allowing XP Pro to rebuild them, and re-configured tcp/ip, and rejoined. I dis-joined from the local W2K domain and re-joined. I have updated the Linksys WRT54G Wi-Fi Routers on each of our office LANs to the latest firmware. So far, nothing has worked. The m205 works flawlessly at home and on hotel WLANS, but can’t access Web sites nor ping their servers’ DN or IP. Yet the C840 and ze5000 can – with nothing changed in tcp/ip.

Any ideas?

If you PC pulls an address and you can ping inside your network I would say most likely your PC is fine! This sounds more like a routing or access control list issue. Where I work we do block IP's from accessing the INTERNET with ACL's on the network devices. Do you "keep" the same IP address at work? Maybe your default gateway router has an ACL blocking external access. Try manually putting in a static entry of a know good PC (make sure to disconnect that PC temporally) and see if you can escape now.

SF18C, same problem with the different static IP.

And, after I connected the Tablet PC (TPC) back on my home network (DHCP), I could then no longer authenticate via
login script to my W2K Server/A.D. at work. But I could manually MAP a drive to a network share, by entering in
another Domain Admin ID & PW when prompted by an authentication pop-up (the same used to join a PC to a Domain), after the MAP failed on my existing logged-in ID with the following error: "Logon unsuccessful: The user name you typed is the same as the user name you logged in with. That user name as already been tried. A domain controller cannot be found to verify that user name." And if I logged in as the other Domain Admin ID, the reverse would occur - I had to authenticate as another user - my ID then would work and not the logged-in ID.

Also, I
1. deleted the Forward and Reverse entries in the Primary DNS's tables (Active Directory), and deleted the object for the TPC in A.D.
2. checked the DNS suffix in IPCONFIG, and compared to two working PC's - the TPC had xxx.com (our web server) as well as xxx.local (our File/Print/Domain/DNS server), one working PC had only xxx.local, the other only xxx.com - both worked. I set the TPC to xxx.local. --> Now I can connect through the gateway to any web site! BUT I still cannot MAP drives, though I can ping the IP of the DC server, and ping it by name, but NOT by FQDN!

I am even more stumped.

Any help would be appreciated.
