You need to Disable Script Debugging -- AND UN-check the box that says "Display a notification about every script error".

Can you ping something beyond your gateway and get a 1472 buffer packet through? For example, try pinging http://www.speedguide.net.

If you can ping your gateway with a full size packet (1472), then at least your computer and your connection to your gateway is set up correctly. Something between ...

Can you ping anywhere else with a larger packet? Can you ping your gateway address with a larger packet?

An NAT router is a good inbound firewall, but it offers no outbound protection.

Most security-minded users prefer to add a software firewall to prevent trojan programs or spyware from phoning home.

I have multiple projects planned... now how many will really get done, that is another story. ;)

I found out I actually CAN use the WshShell object to edit the registry in VB6. The code should be this instead:

Help a dumb and confused newbie.

If I use VBScript or even VBA, I can edit the registry by Creating the Windows Scripting Host Shell Object and then using simple commands like RegWrite or RegDelete:

However, as best I can ...

If you get picky, IE6sp1 does introduce a few minor security patches that have not been offered for earlier versions of IE. How important are these? Like most security patches, they have not been taken advantabe of yet 'in the wild', so your risks are very low. I suspect if any real threat was ...

It's in the registry as a Context Menu Handler... but, whatever! Good luck.

Do the WinRar items appear in EVERY file type's Context Menu -- or just some files? If so, which ones?

I assume you already un-installed WinRar and it left these behind?

You will need to dive into the registry to get rid of these entries. What you are talking about is called a "Context Menu ...

The Folder should be in a different location in Win2K -- it will be user specific.

Can you find a folder called "Temporary Internet Files"? If so, can you open it and look inside?

I am not sure this will help, but if you have TweakUI it might be worth a try:

You can download the SG TCP Optimizer and set these numbers on the "Other Settings" tab. Default levels are:

Max Connections Per Server: Default = 2
Max Connections Per 1.0 Server: Default = 4

Alternatively, you can use regedit to reset the values here:

Are you using a Netgear router or just a Netgear card?

As above -- it is your router that is the problem.

Pull the notebook out of the circuit and see if the problem still exists. Something is over-writing the MSS field of your SYN packet. If you don't use PPPoE software and you have no other 'router', then the notebook is the most likely candidate.

You ISP can also do that, but that is VERY rare.

Using Restricted sites does not block your computer from reaching the site in question, it only disables that site.

You can block your computer from reaching sites by using a Hosts file . This does not prevent the actual pop-up from opening -- a blank IE window can still be opened -- but a least ...

You don't want TTL too low with a large RWIN -- there will be a critical point if your RWIN greatly exceeds your bandwidth.

Think about it. If you have a HUGE RWIN and small bandwidth, the packets will have left the server and will be sitting in limbo for a long time waiting to get through the ...

Router?

Sorry to confuse. It is all the same issue -- look at all the numbers carefully. MS just FORGOT to update the MSKB article. The Win98 update *has* been available from the MS02-050 Security Bulletin page since 9/5/02. If you have that update, then that is it!

One more to add to the list:

There is no reason to apply the patches AND use the Optimizer.

rmrucker

Got it. But it remains illogical that scaling would be helpful if the RWIN is under 65535. Turning on scaling has *nothing* to do with the "window" field in the SYN packet. Therefore, there is no logical "cause and effect relationship". But I guess one can never exclude random luck or voodoo. ;)

rmrucker

You are correct! Sorry. I was looking at 32470 and seeing 324700!! My mistake -- I stand corrected.

You should not see 65535 if your RWIN is set lower than this. I have to suspect something is interfering. I suspect you have rebooted, but I always have to say that again just to be sure.

Then, are ...

rmrucker

The Analyzer is reporting correctly. It is not a Windows or an Analyzer problem. Everything is working as it should.

If you TURN OFF scaling, then it is NOT possible for your ReceiveWINdow to be over 65535. Sure, you can set the number higher in your registry (using regedit, the Optimizer, or ...

rmrucker

Yes, that is a good way to look at it. The 1.5 x latency is a fudge factor that was made up out of thin air.

You don't want to just ping ONE site (such as http://www.speedguide.net ) and determine that your latency EVERYWHERE will be the same as that. Latency will vary with distance as well as ...

Sounds like an out-of-date vtcp.386 file...

You cannot use Windows Scaling in Win98 until you upgrade vtcp.386.

I don't see any mention of the two updates that all of us should have:

How exactly is that 'sandbox' constructed? What keeps javascript in a web page from accessing a user's file or the user's registry?

Are the 'evils' of HTML and JavaScript completely limited to vulnerabilties? That would seem likely -- the sandbox is maintained unless there is a leak.

rmrucker

I have to agree -- if you need to ask how to add things to your registry, I would HIGHLY recommend against adding anything!

What OS? Are you seeing a Windows Scaling value? Can you Cut&Paste your Analyzer output?

OK, just another ignorant question from me...

If it is your NIC that is controlling the MTU, then getting a T1 line connected to the same NIC is going to give you the same MTU!

However, if it is a router that is controlling the MTU, then dumping the router will give you an MTU of 1500 whether or not you have the T1.

But, your speed is fine ...

You should be able to set up restrictions to downloads and the Security tab that are user-specific. Have you tried using the Group Policy Editor?

You could try to ping your own IP address and see if you can get a full size packet (-l 1472) to work. Then run a tracert and see how far a full size packet can go. If it does NOT even get as far as your IP address, then the limitation is in your computer.

rmrucker

That's a lot of routers to go through! Any one of them could be limiting you. Can you ping the webserver with a full size packet (1472 buffer)? Can you ping anything else in that chain?? Perhpas you can locate the bottleneck that way...
