Firewall is Dead
Service pack 2 for Windows XP has included a software firewall that is intergrated with the operating system. Sometimes things get out of whack with it and simplist thing to do is simply to reset it. This can be done from the command line.
Here's how
If you have SP2:
- Click Start then Run
- Type cmd and hit Enter
- Type netsh winsock reset and hit Enter
- Follow prompts and reboot.
If the machine is pre-SP2, use the WinsockXPFix program.
If that didn't work, see if registering the following DLLs helps:
- From Start click Run
- Type
regsvr32 %windir%\system32\atl.dll and hit [enter]
regsvr32 %windir%\system32\hnetcfg.dll [enter]
regsvr32 %windir%\system32\netshell.dll [enter]
regsvr32 %windir%\system32\netcfgx.dll [enter]
regsvr32 %windir%\system32\netman.dll [enter]
You'll get a dialog box saying the .dll registration was successful after each [enter]. Then do a reboot.
