Hello,
Please help me identify why my Direct Access server is losing access to the Domain Controller.
Background:
- we already have a running DA setup, but a single-NIC one
- dual-NIC setup is what I'm trying to do
- IMPORTANT: The internal NIC is in the same VLAN as the running single-NIC server, which means this is not a firewall issue
Configuration:
- gateway specified only on the external adapter
- DNS specified only on the internal adapter
- Bindings: Internal network interface is listed first in the list of connections.
- Static route is specified for the internal network
What's happening:
- everything looks ok when the Direct Access server boots up, dashboard green etc.
- after about 20-25 minutes, connection to the Domain Controllers is lost
- Domain Controllers remain pingable
- Get-DAEntryPoint : A domain controller cannot be reached for [domain.name]
Tried going through the event viewer but could not find anything that could point me in the right direction. Any help is appreciated.
Kind regards,
Wojciech
EDIT:
Forgot to mention. I have a second server prepared in a similar way when it comes to the NIC configuration as I plan on setting up a NLB cluster. The difference is that I had not completed the Direct Access initial setup. This server does not experience any issues with domain connectivity. Which means this is 100% not network related, but probably it's a GPO/DA setup problem.
