OK, I have changed the permission for the SYSTEM "Deny" for the following keys that keep changing:
MaxGlobalTcpWindowSize, TcpWindowSize and MTU for the Sierra Device Interface key.
I'll test it now and respond, I hope I have not screwed the registry up in the process.
Hello and welcome to justanswer.com my name isCustomerXXXXX I'm here to help you with your networking question.
Rather than tweaking the registry yourself I recommend & use the free TCP Optimizer which will do all the settings for you.
You can download it here
I used SG TCPOtimizer. Already been there and done that.
DRESteve2000 told me to reset SYSTEM permission amd now I have the Black Screen of Death! The following message appears:
lsass Application Error
The application failed to initialize properly (0xc0000142)
Click OK to terminate the application.
Thank you for your reply
Sorry but you didn't mention that you had tried TCP Optimizer and I don't know why you're rating me bad service when I didn't give you the registry instruction.
If you are now getting a black screen of death and can't boot into Windows in order to do a system restore or registry restore then please press the f8 key when you boot up your computer and choose the "last known good" option and see if you can boot up.
Let me know how it goes.
I'm not rating you I'm rating DRESteve2000 with bad service.
Thank you .
Sorry but the rating has appeared next to my entry. I'll alert Customer Service.
By the way have you been able to boot up please?
Not yet. I have a dupe copy of the hard drive I am responding to you now.
I am starting the Microsoft instructions on recovering the system from the recovery console.
Before you try the Recovery Console ...
If the f8 "last known good" is not working, you can launch System Restore this way:
When you press f8, choose safe mode with command prompt
1. Your computer will then boot to a command prompt (dos window). C:\....... you want to note what comes after the c:\ because you may need to change the default directory.
2. Change the directory by typing.
cd c:\windows\system32\restore\ Then press the Enter key.
3. Then press the Enter key.
4. Type: rstrui.exe
A couple of other things come to mind.
Are you using a D-Link network adapter?
If so, use the XP device manager to disable the "4X Mode" and see if that stops the MTU from being reset.
I assume when you change the MTU with TCP Optimizer you are selecting to change the correct adapter :-)...I only mention this because I made this mistake myself when I first used it.
Using TCP Optimizer and resetting the Rwin and GlobalMax Rwin
resets the TCP optimized values from 130560 130560 to 513960 513960 respectfully XX XXXXXX (always). There must be a way of keeping the device from resetting values!
Hello there sorry about the delay in replying. We are in different time zones and I had problems with the Internet here in South Africa last night.
Did you see my answer above where I mention the D-Link network adapter?
You can check this out by typing devmgmt.msc in the "open" field of start>run
You will see the Device Manager open as shown in the image at the bottom of this answer.
Under the devices you will see your Network Adapters. If you expand the entry and you see that you indeed have a D-link adapter, then please double click the entry to show the properties. Look for the the 4x Mode option and disable it.
The issue lies in the driver for the adapter which stops the MTU from being change in order to facilitate a faster network data speed.
Attachments are only available to registered users.
There is no D-link network adapter, only USB\HSPA_DEVICE\6&A081329&0&7&012701004639620, which is the Sierra754S 4g Air Card.
O.K. however I don't believe it will resolve the adapter problem.
My window of resolution is closing since I am signed up for the 7 day free trial. We are going out of town early tomorrow and won't be back until the trial runs out. If you want to scan my system, do it now otherwise I shall call for a refund.
Yes, send the refund request. I appreciate your time.
