Hello TechNet,
One of my customers are experiencing issue with GPO executions during logon, especially the map network drive.
My GPO settings are set to await network connectivity before running.
The network drive GPO, is set up with the update action, and reconnect enabled.
As an example, one PC is connected wired to the network.
It's a flat layer 2 network, no subnet segmentation and no firewall in-between.
When the user logs on, it takes a while. After, the network drives are not loaded (even though I have my settings as mentioned).
When I look the event log, I see warnings and alerts with DNS towards the domain controllers, and GPO not being able to run due to no connection to DC
But if I execute an NSLookup and as for the domain or domain controllers, it resolves. Also after an IPCONFIG /FLUSHDNS and reboot.
If I clock on the "disconnected network-dive" I get connection the the drives.
I've been searching the web for troubleshooting steps and where to start. But I havn't found a solution that works yet.
A bit more info:
Domain controller are 1 2003 server and 1 2008R2 server. Both are internal DNS server as well, pointing towards each other as primary DNS.
They are virtual
The PC is connected to one access switch, with an 1Gb/s uplink to the core switch. The hyper visor are connected to the core witch as well with several 1Gb/s uplinks.
Network speed test show close to 1Gb/s internal with both down-and upload from PC to server
Looking forwards to hear some suggestions.
Kind regards
Jonas
