IPv6 RDNSS and DNSSL on Cisco IOS XE

The official documentation on Cisco IOS XE for Catalyst 4500E claims this is the syntax for specifying IPv6 RDNSS and DNSSL:

Switch(config)# interface Te1/1
Switch(config‑if)# ipv6 nd ra dns server 4::4
Switch(config‑if)# ipv6 nd ra dns search list aaa.cc.com

Using IOS XE 3.10.0E, the correct syntax for DNSSL is:

Switch(config)# interface Te1/1
Switch(config‑if)# ipv6 nd ra dns server 4::4
Switch(config‑if)# ipv6 nd ra dns‑search‑list domain aaa.cc.com

Sadly, the quality of Cisco’s documentation isn’t what it was back in 2006.

Error 0x800F081F while installing .NET Framework 3.5 on Windows 10

Error 0x800F081F while installing .NET Framework 3.5 on Windows 10 might be due to corporate WSUS servers not allowing such updates.

Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU in the Windows registry and set UseWUServer to 0 (zero). Restart the Windows Update service (net stop wuauserv & net start wuauserv) and retry installing .NET Framework 3.5. Set UseWUServer back to 1 (one) and restart the Windows Update service.

Star Trek Online and InstallLocation

I keep Star Trek Online installed in two separate directories. One of the copies is simply a backup which I update but never play, while the other is for playing.

Keeping these two copies updated got a bit messy after the STO launcher began recording the InstallLocation in the Windows registry.

Subsequently, I have to remove this value from the registry prior to launching the game from another location.

@echo off
reg delete "HKEY_CURRENT_USER\Software\Cryptic\Star Trek Online" /v "InstallLocation" /f
