Re: BDC not serving logons when PDC goes down...

Tech-Archive recommends: Fix windows errors by optimizing your registry

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
-> 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.

Yes all clients point to DC1 and DC2 for DNS.

Do the clients that use domain services point to another dns server when
this server is down? This is usually the case, people forget to change the
clients.

I have two DCs set up as Global Catalogs. The issue I am running into is
when I power off DC2 and try to log into any workstation/server on the
domain

it simply says "Inavlid Password". Then, as soon as DC2 comes back up the
logins works perfectly. Why is DC1 not serving netlogon when DC2 is down?
