Hi all,
I'm having a very painful and hard to diagnose issue with my network at home.
Here is the basic layout:
Router - Linksys RV082
Switch - Dell Powerconnect 5424
Virtual host - Poweredge 2950
2 domain controllers (server 2008 r2), both virtual machines. One has DHCP
THE PROBLEM:
Whenever I open (or try to open) a website, it sticks on "Resolving Host" or the browser equivalent for a long time. 5, 10, 20, 30 sec. It is excruciatingly painful.
WHY I THINK IT'S DNS
I have one VM on it's own nic, seperated completely from the rest of the traffic, and using the router as DNS. It works perfectly.
WHAT HAVE I TRIED:
I've tried a different router, tried a different switch (Basic netgear 8-port gig switch), tried going directly to the router, put my dns servers on a different NIC.
WHAT HAS CHANGED IN MY ENVIRONMENT:
I demoted an old Server 2003 DC (wasn't holding fsmo roles) and removed it from the environment. I cleaned up the old metadata. I then put in place its replacement, a 2008r2 VM.
Please help :( I'm not sure how to go about troubleshooting further, what to look at, or anything.
Thanks
