Thank you Kent, that worked - I changed the second parameter to TRUE and set my owner password and now it's working on a local TPM.
Trying to do the same operation on the same TPM from a remote server using the tcsd network service, I'm now getting TPM_AUTHFAIL. I enabled the "readpubek" remote operation in /etc/tcsd.conf and restarted tcsd. All I'm doing to access this remotely is taking the same code which is now working on the local host and running it on another system, passing the IP address to my original host as the second parameter to Tspi_Context_Connect. I've used that successfully to get remote quotes. Has anyone been successful in calling Tspi_TPM_GetPubEndorsementKey from a remote system? Are there any differences between doing this locally and remotely now that I've successfully done it locally?

That return code doesn't make sense to me either. Passing FALSE as the second param means the TPM must be unowned for that to succeed. Is that what you intended?
