Client can't open some web pages
lhhood423 Apr-24-02 09:47 PM
I have two computers networked with a crossover cable (25'),host is running Win Xp with IE 6.0 and client is running Win ME with IE 5.5

Problem, client can not open web pages that the host can, client also can't ping these sites to name some,microsoft.com,excite.com & kodak.com are some that I have this problem with. This has gone on for some time now so its not the sites and I have reset IE 5.5 Internet options to default and still with no luck.

Thanks for any help you can offer.

How fast can you copy about 100 MBytes between the two hard disk drives on the two computers? Try copying the files, just the files, not the sudirectories, in d:\win9x on the Windows 98SE CD to a folder on one of the hard disks and then copy them to another folder on the other hard disk. Believe that's about 110 MBytes. Larry

101MB from host to client 4min 20sec
101MB from client to host 6min 45sec

That's far to slow. It should be around 45 to 70 seconds, depending on the computers. The crossover cable is probably defective. See http://duxcw.com/faq/network/link.htm and http://duxcw.com/faq/network/slownet.htm for enlightenment. Larry

I had a similar problem. Client wouldn't load all graphics from web pages. Copy of 100 MB between computers was also slow - about 2 to 3 minutes. I loaded Opera browser on the client computer and voila -- problem solved. Everything loads on that computer now and quickly.

You still have a problem, which you may or may not want to solve. Larry

Can't access some websites while using a shared PPPoE connection

Intended For
Windows XP
Windows 2000
Windows Me
Windows 98

If you're using Windows' built-in support for Internet Connection Sharing, and your Internet connection is facilitated by PPPoE software (such as Enternet 300) or Windows XP's built-in PPPoE, you may experience this problem. Although any web site will be accessible on the "Host" computer, certain web sites will never load successfully from any of the "client" machines. (If you don't know what "Hosts" or "Clients" are with regard to ICS, read Internet Connection Sharing.) The problem is caused by an incompatible MTU networking setting: Windows' default is 1500, but PPPoE uses 1492 or 1454. Here's how to fix it:

Find the IP address of your gateway. If you're using Windows 2000 or XP, run IPCONFIG at a command prompt on the Host computer. If you're using Windows 98 or Me, run WINIPCFG on the Host computer. Either way, you'll get an address that looks like xxx.xxx.xxx.xxx (where the x's represent numbers).
Then, go to one of your Client machines, and type the following:
PING -f -l 1500 xxx.xxx.xxx.xxx
(where xxx.xxx.xxx.xxx is the gateway address you obtained in the first step). You'll probably get an error message indicating that it must be fragmented. If you do, type the following:
PING -f -l 1492 xxx.xxx.xxx.xxx
If that doesn't work, try this:
PING -f -l 1454 xxx.xxx.xxx.xxx
The numbers in each of these examples (1500, 1492, 1454) are the MTU values. Continue issuing this command with lower and lower MTU numbers until you get ping responses instead of an error message. The highest MTU value that works is the one you need to be using. If an MTU of 1500 (the first command, above) does not produce an error, then this solution won't work for you.
The next step is to configure all your Client computers to use the new, lower MTU as the default for all Internet communication.
Windows 2000 and XP:

Run the Registry Editor (REGEDIT.EXE) on one of your "Client" machines.
Navigate to HKEY_LOCAL_MACHINE\ SYSTEM\ CurrentControlSet\ Services\ Tcpip\ Parameters\ Interfaces.
There should be several subkeys under the Interfaces key; most likely, you'll find three. View the contents of each key by clicking, and find the one that corresponds to your primary network adapter; it will be the one with more values than the other two, and will have an IP address value set to something like 192.168.0.x.
Once you've found the correct subkey, create a new DWORD value in it (Edit -> New -> DWORD Value), and name the value MTU.
Double-click the new value, choose the Decimal option, and type the MTU value determined above.
Click Ok when you're done - you'll need to restart Windows for this change take effect.
Repeat this for each Client machine.
Windows 98/Me:

Run the Registry Editor (REGEDIT.EXE) on one of your "Client" machines.
Navigate to HKEY_LOCAL_MACHINE\ System\ CurrentControlSet\ Services\ Class\ Nettrans\.
Under that branch, find a key (numbered, such as 0005) that contains has TCP/IP assigned to the DriverDesc value.
Select New from the Edit menu, then String Value, and type MaxMTU for the name of the new value.
Double-click the new value, choose the Decimal option, and type the MTU value determined above(mine is 1454).
Click Ok when you're done - you'll need to restart Windows for this change take effect.
Repeat this for each Client machine.

Thank you for the input. It should help others. Did that improve the benchmarks on copying 100 MBytes between computers? I would really like to know as I thought bad cables caused some/most of these problems. Larry

Larry, sorry it turns out that I was transferring a 264MB file,when I
received my first benchmarks so this may not help any, but I ran the test
again with a 98.1MB file & the times where client to host 1min. 50sec. /
host to client 1min. 18sec. Again thanks for all the help you offer to
people.

Unless the computers are quite old and have old hard disk drives that is a bit slow. I am getting benchmarks for 105 MByte transfers that are inside of one minute. Larry
