Configure DNSCredentials

Posted by bartvdw on 0606/1010/2008

If you run DHCP & DNS on 1 and same server, Microsoft recommends to use DNSCredentials for secure updates. For this, create a dedicated user account with a very difficult password set, but make sure the password is set to ‘Never expires’! No special group membership is needed for this user.

The run following command (command-line): netsh dhcp server set dnscredentials %USER% %DOMAIN% *

Note: the * sign at the end of the command enables prompt for password. When prompted, enter the password of the user.

Read the article below for more information.

Antivirus software exclusions

Posted by bartvdw on 1313/0808/2008

When you configure antivirus software for servers, you need to take exclusions into account. And for MS products, they are fairly good documented. If you don’t add these exclusions, you could get trouble/errors. For applications not listed here (MS or third party), always verify if you need to exclude something to make sure your antivirus software does not affect your application!

Below a summary of such exclusions and references to MS articles describing these exclusions. I will update this post in case I have additional information.

Note: In the list below, default file locations are used. If you have change the location of the files (ex. Ntds.dit), you need to use the altered path obviously!!

General exclusions Windows Server 2003, Windows 2000, Windows XP, or Windows Vista:

Allocated memory issue: sqlservr.exe

Posted by bartvdw on 2626/0101/2008

Recently I found on a SBS 2003 box a memory issue. After a quick look in my Task Manager I found that the process was called sqlservr.exe

Next step was finding the service linked to the process. “tlist.exe -s” (included in Debugging Tools for Windows) gave me the information needed: MSSQL$SBSMONITORING

What to do about that? Well after searching a little bit, I found this solution:

  • Open cmd
  • osql -E -S YOURSERVERNAME\sbsmonitoring [hit enter]
  • sp_configure ‘show advanced options’,1 [hit enter]
  • reconfigure with override [hit enter]
  • go [hit enter]
  • sp_configure ‘max server memory’, 70 [hit enter] (based on the information I found, this is OK)
  • reconfigure with override [hit enter]
  • go [hit enter]

Note: mind the quotes used! I have problems with publishing them correctly, so if you receive an error pointing into that direction, correct them manually in your syntax.

Cool link that helped me a lot:
