Windows 7 DNS issues after Windows Update

[Matsuo]

Hi all,

Since a few months I've been experiencing several connection drops during the day. According to the log files it's a [FONT=inherit !important][FONT=inherit ! important]DNS[/FONT][/FONT] issue, addressed as Event ID 1014.

Things I've tried (without effect):

- Disconnecting my router
- Disabling DHCP on the router
- Setting up a static [FONT=inherit !important][FONT=inherit !important]IP[/FONT][/FONT]
- Using Google and [FONT=inherit !important][FONT=inherit !important]OpenDNS[/FONT][/FONT] servers
- Removing and reinstalling the Link Removed for my NIC (onboard Realtek adapter, and I've used the Realtek and the Windows ones)
- Changing the cables between modem, PC and router
- Repairing the TCP/IP protocol
- Flushing DNS
- Resetting DNS
- Disabling auto-sleep on the NIC

Things I've noticed (from the log)

- The linked services were: CryptSvc, Dnscache, LanmanWorkstation and NlaSvc
