Hidden IPv6 on XP and Server 2003

article #431, updated 4603 days ago

Sometimes IPv6 is installed on XP in a hidden form — sometimes IPv6 may be installed, but not visible in any Windows GUI. To find out, go to command prompt and enter:

netsh show helper

If IPv6 is installed, in that list will be “ipv6”. To uninstall on XP, run this:

ipv6 uninstall

The ipv6 command does not exist on Server 2003. The following does:

netsh delete ipv6mon.dll

Hidden IPv6 has been shown to cause problems in some Oracle environments.
