Strangely when I selected the SAS storage controllers they could see all 5 storage LUNs,...
Reset IBM / Lenovo IMM Username and Password
KB ID 0001291 Problem After recycling an old M3 3650 IBM X Series server the other week, I was stuck trying to get into the IMM, because no one knew what the password was. The default username of USERID and password of PASSW0RD (with a zero) didn’t work either. Solution For me it was OK because I could reboot the server and get directly into the BIOS , (Press F1 at boot) System settings. Integrated Management Module. Reset...
Audacity – Looping Audio (Repeating Sections)
Looping Audio KB ID 0001290 Problem Those that know me, will know I’ve been struggling to learn the guitar over the last few months.

Can A Domain Trust Another Domain With The Same ‘Root Domain’ Name?
KB ID 0001288 Problem About a month ago I was with a client to do some investigation/consultancy, they were a large company with their head office in the UK and a number of other offices around the world.

Avaya / Nortel Switch Notes
KB ID 0001285 Problem I don’t often use Nortel (now Avaya) switches, I know they are decent, but in my day job I usually work on Cisco, occasionally HP, and other cheap assorted nastiness switches. I was replacing an old 10/100 Cisco 3750 switch with a Nortel 4526GTX this week, and thought I’d take some notes for the common things I do, just in case I have to do another. So this post is an eclectic collection of the...
