Can anyone help with this please, we are experiencing intermittent connectivity between devices connected to the same switch and within the same vlan. This is now every hour and the outage lasts about 3 to 5 minutes. The server guys report RDP and DNS connectivity errors - The connectivity verifier "x.x.x.x RPC" reported an error when trying to connect to x.x.x.x.
Reason: The request has timed out.' and the servers lose connectivity to each other. I have checked several times ans all ports are fine with no errors, the vlan is functioning fine, all servers have speed/duplex forced and use the same def gtwy etc.
The switch has even been replaced but yet these problems persist.
The server guys have changed nic, drivers etc on all three servers affected.
Any ideas, getting desperate???
