Re: Load balancing strange issue



Hi Rod, thanks for the quick response.

Yes NLB does converge. When adding the server to the NLB cluster I see that
the server having problems is converged. But after that, it can not connect
to the other member.
There are no errors or warnings in the eventlogs only information about the
configuration changes:

Configuration update 12 completed with status 0x0 on adapter
{13EF3CB7-705B-417B-B5D7-C2A5860B49D5}. Information log contains:
Processing update 12 from "NLB Manager on OWA1.domain.com"
Starting update...
Going to bind NLB...
Bind operation succeeded.
Cluster configuration stabilized.
Going to modify cluster configuration...
Modification succeeded.
Going to modify the IP address list...
The IP addresses list modified successfully.
Update completed successfully

Both the servers have the same Certificate installed. Both servers work fine
if I connect to them individually.

Thanks
