LSASS error "requested operation was unsuccessful"

[TomB]

I have been plagued for about a week with a LSASS requested operation was unsuccessful error. It happens shortly on boot after a successful XP image deployment on Dell laptops (my HP laptops never had this error). After examining everything I could think of I finally figured out what the problem is and I wanted to share the issue and recommend a change to FOG to prevent this for others.

The problem was the computer name length. The netbios name length is limited to 15 characters but in the FOG host screen you are allowed 16 characters. I was creating the host name by prepending the autogenerated host name MAC with Dell so my computer name was Dell123456789012… thus 16 characters. (My HPs were only 14 characters so they never had the issue…)

Please consider changing the Host Name length to restrict it to 15 characters.

Hope this helps someone else.

Rgds,
Tom
