SBS 2011 ADWS crashing

Hi all,

I have an SBS 2011 migrated from SBS 2003 via Swing Migration.  We had a UPS go bad and did not have a graceful shutdown.  We are now getting ADWS event 1400 but no 1401.  I did get the 1401 previously when I installed the GoDaddy UCC cert.  Can anyone tell me how to fix this?  It has been crashing ADWS and we have to restart daily.  Thanks!

Hello IslandTom,

I recomend to use native diagnostic tools at first:
1, fix my network wizard
2, SBS best practices analyzer
3, health scanner
4, netdiag from support tools (run as admin)

Let us know if any errors..

GO to the question Every time I boot my domain controller it logs this warning........... Event id 1400........

Jarda, Thanks I am running.  Rusty, I have read this but am not sure how to fix it.  

DCDiag test returned NCSecDesc NT Authority\Enterprise Domain Controllers doesn't have replication directory changes in filtered set, DC Forest DNS Zones and DC-Domain Zones.

This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.

Please proceed with your troubleshooting , however regarding deploying  an MS Enterprise PKI, by getting a Domain Controller certificate through auto-enrolment can be achieved as per the following article. These article are lengthy one so while doing troubleshooting you can go through it and if you want to follow do have a backup and then proceed :-



Thanks for the comments all.  I have a case going with MS critical down.  I'll let you know how it goes.  The "episodes" begin with ADWS Instance event 1206, ADWS was unable to determine if the computer is a global catalog server.  Followed by that repeating event a few times.  Next DNS 4016, 4015, 4004.  I've been restarting ADWS and DNS Server services almost hourly to keep the users going.
