0Batch script to rename PC based on reserved DHCP name

Published by & filed under Windows. Last updated .

I use WDS on a stan­dalone serv­er to set up new PCs and to reim­age PCs when they have ended up mangled bey­ond repair. With a good num­ber of PCs in my own house it is use­ful to reim­age them oca­sion­ally when swap­ping or upgrad­ing hard­ware. Most of this pro­cess is now auto­mated by an unattend.xml file but one step the unat­ten­ded pro­cess does­n’t seem to sup­port is renam­ing PCs back to their ori­gin­al name.

0windows 8 logoWindows shares not connected after wake fixed

Posted by & filed under Windows.

0Tin full of spamHow to reduce spam with SPF, DKIM & DMARC

Published by & filed under Web Technologies. Last updated .

Since I set up con­tact forms on vari­ous web­sites I’ve had a slowly increas­ing volume of spam. Not dir­ect spam sent to me, but bounces from non-exist­ent addresses that were being spamme, appar­ently from my address. Unfor­tu­nately the spam was­n’t ori­gin­at­ing from my address, but my address was some­how picked up (prob­ably from before I secured the con­tact forms on the site) and was being used as the “reply to” address. After some invest­ig­a­tion I heard about SPF which is an e‑mail anti-for­gery system.
