Known issues

Troubleshooting

Cannot modify system's hosts file?

A wrong configured hosts-file can lead to problems with the Windows DNS-Client. Annoyingly the DNS-Client will crash, if the hosts-file is very long. If the DNS-Client blocks access to the hosts-file, you cannot edit it anymore. To solve this issue

• disable the DNS-Client REG add “HKLM\SYSTEM\CurrentControlSet\services\dnscache” /v Start /t REG_DWORD /d 4 /f
• Reboot and delete or backup the hosts file
• enable the DNS-Client REG add “HKLM\SYSTEM\CurrentControlSet\services\dnscache” /v Start /t REG_DWORD /d 2 /f
• Reboot
