Repair Windows XP TCP Network Settings With WinSock XP Fix Utility


winlogo.jpgOne of the more difficult troubleshooting tasks on Windows XP computers is fixing Network related problems. More often, resolving the problem means re-installing Windows XP. While no method exist to uninstall a damaged or corrupt TCP Network stack on XP, a free utility does offer a last resort to cure and repair Network connection related problems

WinSock XP Fix is a utility, with a good track record of fixing and repairing the following problems:

  • Corrupted Networking or Winsock (Windows Socket Interface) problems on Windows XP caused by missing registry entries.
  • Lost or slow connection issues due to Spyware and Adware removal tools during clean up.
  • Installation of programs or tools that modify Network and Winsock configurations.
  • Wireless related connection problems,
  • Issues caused by Microsoft updates and patches.
  • PC not obtaining DHCP address.
  • No connection or low signal when connecting to Internet Cable/DSL modems.
  • Network driver problems or Winsox errors

WinSock XP Fix is free, requires no installation and involves two steps that will backup the registry (if selected), then attempt to fix Network problems and display status results during the repair step.

As always, before running any tool or utility as a last resort, backup any data you do not want to lose.

Run WinSock XP Fix following these steps:

1. Download WinSox XP Fix to your Desktop, then click on WinsockxpFix.exe to start program (no installation is required).

2. After the utility opens, you will have two options available, Fix or ReG-Backup (registry backup). Since you are running the tool as a last resort, decide if you want to backup the registry or go ahead and Fix.


If you choose to backup the registry, click on ReG-Backup and in the next window, select a location to Backup to: (or accept default location) and select all Backup options (System registry, Current user registry, Other open user registries) and click OK.


3. Click Fix and click Yes to Apply the VB_Winsock fix?

4. The amount of time needed to repair will depend on the number of Network connections and Protocols installed on your system (be patient). After repair has completed, click Ok to reboot

With any luck, your Network connections will be repaired. As a final checklist, verify your Anti Virus and Spyware programs are working correctly. If you have a VPN connection make sure all settings are configured properly. Re-install any component or program that do not appear to be working.

WinSock XP Fix may not be a perfect utility, and there is no risk involved as a last ditch effort to repair TCP network connection issues if you are considering re-installing Windows XP.

NOTE: If you did choose to backup the registry before running the Fix, I do not recommend restoring from the registry backup you created if the WinSox Xp Fix was successful in repairing your Network settings. If the problem was registry related, restoring will just put the problem back in the registry.

If neccessary and you do need to restore the registry backup, go to the folder where the backup was saved (default is C:\ERDNT), and run ERDNT.EXE.

Awesome tool.. Due to a virus outbreak (Sasser, backdoor.rbt, spyware, etc..) my local network access would not function, even after removing the offending software. I would always receive a network error immediately when trying to access any other machine. This tool repaired the damage done to the network configuration perfectly! Wonderful tool!

I heard the WINSOCK Fix worked good on Windows XP SP1, but not so good for SP2. Do you have any other solutions? The fix did not work on my PC which is running SP2. I get the ip address,

THANK GOD FOR THIS TOOL. This will probably fix your problems if you can only connect to networks under "safe mode with networking".

Here's the story. All of a sudden, without warning, one day my computer would not connect to any type of network. At first I thought it was a wireless problem, then I found it was not recognizing even a wired network. I found out I could connect to a network but only in safe mode with networking. After tons of time spent searching google, I found this utility on a few pages marked, "Network adapters work only in Safe Mode – HELP!"

I loaded this tool and my system was magically fixed. !!!!! I love this file.

My wife's computer developed a problem recently where her browser would not resolve anything. Performing a network repair solves the problem; but after a while the problem re-asserts itself. I created a scheduled task to run a repair every 15 minutes – and that works, for now… But, why did this happen in the first place? When I look at the output of the 'netsh ip reset' there are three entries indicating a "bad entry" for the "Linkage\UpperBind" key entries for the NIC, the NDISWAN, and a GUID value where the "bad value" was REG_MULTI_SZ = SymIM . My wife's machine has Norton's Internet Security on it, so I'm assuming the SymIM is a Symantec generated entry. Any ideas or suggestions what to do to resolve this rather than perpetually running 'schtasks /Create /TN RepairIP /SC MINUTE /MO 15 /TR "netsh int ip reset c:\temp\logs\network-connection.log"'

Read the info to understand what it does. Nice util.

However, it did not fix my particular DNS problem. Been scouring the web, tried half a dozen fixes (WinsockXP fix, loaded registry entries, XP network repair, etc) to no avail. Here's the deal:

The router (which multiple machines use, including this one) gets it's info via the ISP DHCP. Machine #1 gets all the appropriate IP info,
can ping IP addresses inside and outside the firewall, but it cannot ping domain names or load pingable IP addresses as websites.

I don't run a local DNS service or HOSTS, so fixes that target them are null. It's not a router problem, nor a DNS problem (again, works fine on machine #2 through the same router), so it has to be a Windows network config problem. I suspect the woes started after I told Glary Utilities to remove broken registry links and optimize the registry, but cause and effect are foggy as I was sleep deprived when the problem occurred. Any ideas, other than not driving a computer while sleepy?

Hi. I don't know if this program will solve my problem, so I'm giving you the scenario. I have a peer-to-peer network with 5 wired pc's and2 wireless connections. I also have wired ethernet connections to a printer, security dvr system with 4 cameras and.

I"m using a 4 port D-Link Gigabit router and an 8 port D-Link gigabit switch.
When the problem started, all 5 pc's were running XP-SP3. When I start all 5 pc's I get an intermittent connection, both LAN and WAN. It is not a regular length nore a regular cycle. It may be seconds and last for seconds, or it may work for minutes before going down.

Since I had the problem, I have had to replace 2 pc's with new Win7 Pro machines. I have tried replacing all hardware in the network as well as my ISP. The problem remains.

Just before Thanksgiving, I tried networking both Win7 machines only, through the router/switch and both seemed to work without a dropout.

What do you think?

I cant format the computer im having issues on. Its XP SP3 that had some viruses attack, it's supposed to be already clean, i have update BIOS, reinstalled chipset and NIC drivers, and did the tcpip stack thing, and this sofware, also tried "repairing" the OS (without format), ive tried installing drivers from a working computer (same make/model of course), used a different NIC, and many things… nothing works…. i cant format. the connection gets established but then it gets lost, sometimes at the first ping sometimes it takes longer sometimes until i try to do some network activity (such as http), clicking "Repair" on the taskbar icon -on the LAN icon- does the trick, but then again, for a split seconds… ANY ADVISE WOULD BE TRUELY APPRECIATED.

Amazingly effective app!!!!
Fighting during one week against non-resolved DNS and dreadul 169.254.x.y IPs.
Apparently everything started with a broken link registry repair sweep. netsh reset commands alone didn't work but winsockxpfix worked without flare at the first try.
Running in windows XP SP3 updated up to March 2011.

Amazing tool, almost i have decided to break my head with a hammer until i found this excellent tool. TCP/IP networking control in Win XP is almost impossible that everybody knows, there is no substitute (except this tool) & format is the only option. My wireless connection showing it is connected, but i can't access web through any browser (with so many re-installations & checked my laptop outside with cable also). In addition probably some one hijacked my network (as it is observable max data is transferring in wireless monitor window). My os windows xp pro sp3, dell inspiron 1520 laptop.

Thanks man for this, may be Lord Jesus sent you to the earth.

Ok, this is dumb… I downloaded the file, saved it to flash drive and went to my 32bit XP machine to see if it would fix it. The program asks me if I want to install some tookbar first, and then tries to connect to the internet. Um, DUH, if I could I would not have this problem.

Fail. Next program please.
