Solved DNS and Networking issues

April 26, 2012 at 06:52:31
Specs: Windows 64
Had a PDC and a BDC in my environment both server 2003, the PDC had power supply issues and was completely switched off but not before another BDC was brought up and promoted to the new PDC server 2008. I now have xp sp2 machines that constantly needs to reauthenticate to the PDC at various times of the day. they lose connection to printers,internet pages not being displayed until IPCONFIG /flushdns and registerdns is done. Dont have that issue with windows 7 machines.

It is a total nightmare !!!

✔ Best Answer
Active Directory has been around for 12 years now. It is still surprising to see folks refer to NT4 concepts when talking about AD.

There are no pdc/bdcs in AD.

Did you run 2008 AD prep for the 2003 forest before promoting the 2008 server to being a DC?

The 2008 server was added to the 2003 domain PREVIOUSLY to the other AD server going down?

Does the 2008 server has all the FSMO roles?

Why do you think its a dns issue?

Have you tried having the problem workstations join a workgroup, delete their computer accounts in AD, and then add them back to the domain?

Hi thanks for the reply much appreciated.

The 2008 server was added to the 2003 domain PREVIOUSLY to the other AD server going down? Yes confirmed with the IT team as the setup wad done before my time here at the company.

Does the 2008 server has all the FSMO roles? Yes that i confirmed. can various servers holds the same FSMO roles?

Why do you think its a dns issue? connectivity to mapped drives and printers only works after dns is flushed and registered.

Have you tried having the problem workstations join a workgroup, delete their computer accounts in AD, and then add them back to the domain? Tried that already.

regards

NO

At least two minimally should hold the global catalog.

connectivity to mapped drives and printers only works after dns is flushed and registered.

Then you have some kind of dns poisoning going on. Could be bad entries in Hosts file getting loaded or bad duplicated dns server entries.

You might be able to confirm that it's a resolution issue by pinging the host of the network drives when the client can't connect. If it gets the correct IP address for the server, then it's not a DNS or other resolution issue. If it gets a different one, then you know it is.

Have you considered that it might be an IP conflict? On the computers that are having trouble, when they are having trouble, run arp /a. If the MAC address doesn't match that of the server, than another computer is using the same IP address on your network.
