changing machine name implications for IIS

Last Modified: 2010-04-13
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?

Did you reset the password on IUSR_ASP1?  Then you have to go into Internet Services Manager and reset the password there as well.

did you synchronize IUSR and IWAN in the metabase too with C:\Inetpub\AdminScripts\synciwam.vbs ?

Synchronize the IWAM(computer_name) account using the steps in the following article Q255770:

The IWAM_machine account may be out-of-sync. The IWAM_machine identity must be
in sync in the metabase, the Security Account Manager (SAM), and COM+. Account
information stored in the Internet Information Server (IIS) metabase is
synchronized with the local SAM, but COM+ applications are not automatically
IIS 5.0 provides Synciwam.vbs to update the launching identity of all IIS COM+
application packages that run out-of-process. The Synciwam.vbs script can be
found in the \Inetpub\AdminScripts folder and can be run using Cscript or
Wscript (see the Synciwam.vbs file for more information).
NOTE: Using Synciwam.vbs will reset all out-of-process applications (medium and
high isolation) to IWAM_machine.

Excellent. Thanks for this info.

Are there any other things that need to be updated if I change the machine name? E.g. registry entries ?

As for Windows 2K , only if you were joined to a domain or you had clients accessing a program on this machine would it cause a headache but other than that you should be fine.

check name records in DNS.

And certificates are often bound to computer names
