2008r2 network/dns issues driving me mad
This is the problem we have:
Server 2008 r2 standard on an ML350G6 4gb RAM, quad core, RAID 5 built with smart start 8.30. All drivers updated to latest version from HP.
Built server, added roles and features - Directory services, DCPROMO, DNS, DHCP.
This is an infant school and 1st time they've had a server - only server in domain
Windows updates all done - took several attempts due to problem below
Network/DNS is really flaky: network icon in taskbar constantly flashes up telling us no internet access. Run a continuous ping to the gateway and we get about 20% failure rate. Plug another PC into same network point and ping is 100%
Joining a pc to domain is nigh on impossible, if you do manage it after several attempts, logon is just as unreliable
RDP into server and every few minutes connection is dropped. Sometimes it will reconnect itself, sometimes it times out.
already reinstalled OS from scratch
HP have replaced Motherboard
googled myself silly looking for a fix. Have turned off eDNS but this hasn't fixed it
