dns has critical issue
Posted on 2013-02-06
hi i have the following:
- master dc win 2003 /ad/dns/dhcp server
- file & print server
- xp desktops connected
i have not made any changes and my network was ok yesturday although i did shut the whole system down all night and all eventviewers did not show any signs of issues.
today i booted my master dc up and in the eventviewer is states:
!the dns server has encountered a critical error from the active directory. check that the active directory is functioning properly. the extended error debug info (which may be empty) ie "". the event data contains the error!
step 1 - ive cleared cache/and old files etc and restarted the dhcp & ok and the dns ok!
step 2 - i accessed the dhcp log and it stated the following:
the log was temporarily paused due to low disk space etc etc
dns update request to the named dns server
dns update failed
dns update successful
step 3 - restarted master dc but same issue
step 4 - deleted temporary files etc & ran defrag on c:\
step 5 - rebooted system
i ran the following:
- dcdiag - all ok
- netdiag - all ok
still same issue above
note: as im not running anything else on this master dc and have not done for quite sometime, i presume somwhere i may just need to remove some logs or something from somewhere.
i did not have this below added before but now i have:
add a new dword value named “repl perform initial synchronizations”, with a decimal value of 0. evidently, this keeps ad and dns from querying each other at the same time after startup.
qn1. can anyone assist ?
