Bit of a strange one configuring nic teams on four DL380's. Two worked fine. Two kept giving me an error "error occured when making a call into the operating system." I tried uninstalling then installing the ncu software but that didn't fix it. Finally I got it working by unticking all the nic services and protocols except the hp teaming service which then allowed me to create the teams. I didn't find out what the actual problem was but this seemed a fairly straightforward work around as the teaming software does this anyway when creating the team.
