WinsockReset

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.

Here`s what it does in order:

1 Resets ownership/permissions on the Winsock/Winsock2 registry keys in case permissions were hijacked.

2 Backs up the Winsock/Winsock2 registry keys to %systemdrive%SupportWinsockReset

3 Examines your Winsock2 registry keys for missing NameSpace/Protocol entries and .DLL files

4 Optionally deletes the Winsock/Winsock2 registry keys entirely, then imports either:
the Default Winsock/Winsock2 registry keys for that version of Windows.

NOTE: This WILL delete 3rd party winsock providers!!!
or your Winsock/Winsock2 registry keys from ControlSet backups on your own system.
NOTE: This MAY delete 3rd party winsock providers!!!

5 Performs these commands:

netsh winsock reset
netsh winsock reset Catalog
netsh int ip reset reset.log (on XP)
netsh int ip reset reset.log hit (on Vista/7)

6 On XP, (optional) renames %windir%System32mswsock.dll and winrnr.dll to .old, allowing Windows File Protection to replace then with ones from dllcache.
WARNING: ONLY use this option if a previous repair with this tool FAILS.

7 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

8 Restarts the PC.
