Hello Walter,

Make sure the DCs use only domain internal DNS servers on the NIC and none
externals like your ISPs. Also run the support tools dcdiag /v and netdiag
/v to check for errors.

Best regards

AD down isn't a qualified error message. What do clients try by the time
the error happens? What is the exact error message? Can you log on to
the DCs by the time the error happens?

Cheers,
Florian

Hello Walter - SOFTVALE

As Florian asked, what does it mean by: "[...] but two of then start getting AD down?"

Since you said there are no errors in the event logs concerning this, how did you determine there is an AD issue?

Hi All

Are the 32bit 2008 DC's? If so, does all the eventlogs combined exceed 300MB
once added. Check this articaled:Technet article
http:://technet2.microsoft.com/windowsserver/en/library/5a86 ab0f-c7eb-45ed-9e5e-514173bf15e31033.mspx
advises the following: On Domain Controllers, the combined size of the
application, security, system, directory services, file replication service &
and DNS server logs ---should not exceed 300MB.

Run diagnostics against your Active Directory domain.

If you don't have the support tools installed, install them from your server
install disk.
d:\support\tools\setup.exe

Run dcdiag, netdiag and repadmin in verbose mode.
-> DCDIAG /V /C /D /E /s:yourdcname > c:\dcdiag.log
-> netdiag.exe /v > c:\netdiag.log (On each dc)
-> repadmin.exe /showrepl dc* /verbose /all /intersite > c:\repl.txt
-> ntfrsutl ds your_dc_name > c:\sysvol.log
-> dnslint /ad /s "ip address of your dc"

**Note: Using the /E switch in dcdiag will run diagnostics against ALL dc's
in the forest. If you have significant numbers of DC's this test could
generate significant detail and take a long time. You also want to take into
account slow links to dc's will also add to the testing time.

If you download a gui script I wrote it should be simple to set and run
(DCDiag and NetDiag). It also has the option to run individual tests without
having to learn all the switch options. The details will be output in
notepad text files that pop up automagically.

The script is located on my website at
http://www.pbbergs.com/windows/downloads.htm

Just select both dcdiag and netdiag make sure verbose is set. (Leave the
default settings for dcdiag as set when selected)

When complete search for fail, error and warning messages.

Description and download for dnslint
