Hi,
I have a problem, have set up 2 servers (2008R2), (on one esxi host at the moment) on the same sub net. These servers have been set up with NLB (multicast) single interface (NLB appears to be working) for IIS. I have setup DFSR to replicate the content and the configuration of IIS (shared config mode, with the config local).
The replication works, but every 15-25 minutes it fails with event id 5014 followed by 5008 then 5004, so starts again (sometimes it says its ok but doesnt actually replicate until the DFSR service is restart).
Replication has been set to use a static port, RPC is set for a fixed port range. I have has the firewall (local) disabled and enabled, same result.
If i set one of the servers to ping the other (ping -t), the error goes away, so appears to be something timing out in the networking side of things.
If i create a second nic, assign it a ip address on a different range, with its own virtual switch,with the 2 server connected, the problem goes away, even though the DFSR service is still using the other nic, but NLB now has an RPC problem, with unable to contact the server.
Any help would be appreciated.
EDIT:
doing an RPC ping to the static port assigned to DFSR, the first reply takes around 9300ms, the remaining are around .2-.3ms. if i again repeat it, it is quick, until a leave it a few minutes then it takes around 9300ms for the first reply.
Is it going to sleep and timing out on waking up?
EDIT2: Appears I was incorrect about NLB, that also get RPC touble also, with "could not read configuration of interface....: error 0x800706ba" and then "the RPC server is unavailable on the specified computer. Error connecting to..." when refreshing the information in the NLB manager, then trying again a minute later it works.
