Adding a Host to System Center Virtual Machine Manager 2008 (SCVMM 2008) fails with a variation of Error (2916):
Specific content is being filtered by a non-Windows firewall. The firewall could be software installed on either the SCVMM 2008 Server or the Host that is being added. More likely, there is a hardware appliance firewall on the network between the two communicating servers.
Test multiple communication protocols between the two systems; the SCVMM 2008 Server and Host in this example. Some firewalls can have content filtering enabled despite showing that it is not. Remove all non-Windows software firewalls and bypass all hardware appliance firewalls entirely long enough to perform testing to verify whether or not they are contributing to the problem.
The following tests are examples of protocols that should always succeed. Test both directions always:
WinRM successful reply example:
Recently a firewall appliance sold by a major vendor showed content filtering disabled and not licensed to be turned on, yet was still filtering specific content. This was discovered through examination of network traces. Do not assume content, protocols or traffic are not being blocked. Perform tests to verify.
