I was installing the OpenAFS tools on one of my Windows 2000 machines and it kept failing, I wasn’t reading the install (left it unattended twice) but I noticed on the third attempt it was stalling on “connecting to the MS Loopback Adapter”. It is probably in the documentation (but the wiki was down and I was feeling like having an adventure)
Anyway, I linked to the MS support page for installing the Loopback Adapter in Win2k.
Have Fun !
