I have recently changed one of my servers machine name from "DELL2" to "ASP1". This all seemed to go smoothly and I deleted the IUSR_DELL2 user and replaced with IUSR_ASP1 (and IWAM respectively). In IIS, I made the default anonymous account be IUSR_ASP1 (from IUSR_DELL2) and this seemed to work.
However, to my dismay I sometimes get a web application error and the following in Event Log.
DCOM got error "Logon failure: unknown user name or bad password. " and was unable to logon .\IWAM_DELL2 in order to run the server:
What do I need to do to successfully change the computer name without having these problems occur?
