DNS problem causing server to hang after dcpromo
Hello,
I just set up a new win2003 R2 server and performed dcpromo. This will be a new dc in an existing domain.
The dcpromo went fine but upon reboot the server hangs at 'Preparing network connections'.
I had installed dns but did not configure it.
I have the network properties pointing to my existing primary dns.
From looking across the web this seems to be a dns issue.
Unfortunately, safe mode does not give me access to address network or dns configurations.
I am also getting this error in the event logs: "the dns server has encountered a critical error from the active directory. check that the active directory is functioning properly. the extended error debug information which may be empty is . the event data contains the error."
I have the option for 'last known good configuration' upon booting, but I am afraid that rolling back dcpromo may cause more problems than trying to resolve this from a dns standpoint.
Any assistance with getting by the logon hang and addressing this issue would be greatly appreciated.
Thank you,
Flynn

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
Before rebooting the server, remove network cable and then boot it. before loging in, plug network cable and then check DNS entries. Put all the entries in the DNS server.
I know this is not a good solution, but it has worked for me twice.

Rbeckerdite,
Thank you for pointing me in the right direction.
While I was not reusing a computer name, I had needed to do a reinstall with this server. Your suggestion caused me to doublecheck my dns entry on the main dc to see if there was a conflict with the previous name. That caused me to notice that the server name was showing an ip from one of the other nics on the new server.
That in turn led me to the fact that having a multihomed machine can cause this type of problem at this time. I disabled the extra nics and rebooted successfully.
Ultimately, I had 3 nics online for one server, which after dcpromo caused my reboot to hang at 'preparing network connections' after going in through dsrm and disabling the other 2 nics and rebooting the issue is resolved.
Thank you.
dariusq, thank you for your response.
