WinsockReset

Current Version 1.2

WinsockReset is a quick n’ dirty utility I wrote to reset the winsock. (This utility is already included in D7 v7.7.72+)

–

There is no hidden secret or special magic it performs, but it can solve a number of issues and is easier than running the fixes manually…

–

Works with XP, Vista, 7, and 8 – and is fully portable!

Here’s what it does in order:

Resets ownership/permissions on the Winsock/Winsock2 registry keys in case permissions were hijacked.
Backs up the Winsock/Winsock2 registry keys to %systemdrive%SupportWinsockReset
Examines your Winsock2 registry keys for missing NameSpace/Protocol entries and .DLL files
Optionally deletes the Winsock/Winsock2 registry keys entirely, then imports either:
1. the DEFAULT Winsock/Winsock2 registry keys for that version of Windows.
  1. NOTE: This WILL delete 3rd party winsock providers!!!
2. or your Winsock/Winsock2 registry keys from ControlSet backups on your own system.
  1. NOTE: This MAY delete 3rd party winsock providers!!!
Performs these commands:
1. netsh winsock reset
2. netsh winsock reset catalog
3. netsh int ip reset reset.log (on XP)
4. netsh int ip reset reset.log hit (on Vista/7)
On XP, (optional) renames %windir%System32mswsock.dll and winrnr.dll to .old, allowing Windows File Protection to replace then with ones from dllcache.
1. WARNING: ONLY use this option if a previous repair with this tool FAILS.
On Vista/7, uses SFC to replace the mswsock.dll file if needed (sfc /scanfile=%windir%System32mswsock.dll) and repeats procedure for winrnr.dll, pnrpnsp.dll and napinsp.dll
Restarts the PC.
