Sharepoint error after change domain

After we rebuild a new Active Directory, my windows sharepoint service could not start.
It showed this error message :
The file exists. (Exception from HRESULT: 0x80070050).
I am sure this is due to SID change of new domain. After googling around I found this website that helps me solve the problem.
The point is that userinfo table in Admin_content_xxxx database has to be updated with the new sid. I use getsid tool to reveal my new sid.
However it shows sid in s-n-n format while sharepoint store sid in hex format. So I created a vb program that convert decimal sid string to hexadecimal. The code is copied from this blog.

Role centers and enterprise portal on Ax 2009

During installation of role centers and enterprise portal I got this error:

Setup cannot connect to the Application Object Server instance (AOS) by using the Business Connector. Confirm that the AOS is running, and that your account (domain\username) is a valid Microsoft Dynamics AX user. See the log file C:\Documents and Settings\All Users\Application Data\Microsoft\Dynamics AX\Dynamics AX Setup Logs\2008-09-11 11-27-45\DynamicsSetupLog.txt for more information.

I have checked that the user already exists in Axapta. Then I tried changed the service account with the same user and it works.
The service account is in Administration > Setup > Security > System service account. Put the username and domain in the alias and network domain fields.

I post this with hope to save time just in case others get the same problem.

Sharepoint service log files grow rapidly

Recently I noticed that I run out disk space in my virtual machine where I install Windows sharepoint services.
I see that the log folder grows very big in size. It is already 2 GB now.
The default log folder is located here :
C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\LOGS\
To avoid it consumes space in C, I change it to different folder which is achieved through:
Sharepoint central administration > Operations > Diagnostic logging.
Then I also change timer job definitions by disabling them (maybe I will enable them once I know more about sharepoint).
