While using the VCB to backup VMs, this error message was logged and the backup was aborted:
Could not connect to ESX host server_name: 554 PROXY service vpxa-nfc not found
Last night this server was patched and after applying patch 1002434 and 1002435 the vc refused to reconnect the esx server back and I had to remove the vc client and then it connected successfully.
My environment is 2 ESX 3.0.2 and VC 2.5 (VCB is 1.1)
I logged a case with VMware and it appears that due to Jan patches 2 lines were missing from the file: /etc/vmware/config the lines were
authd.proxy.vpxa-nfc = "vmware-vpxa:vpxa-nfc"
authd.proxy.vpxa-nfcssl = "vmware-vpxa:vpxa-nfcssl"
Nice of them not to fix these with the Feb 20th Patches.
But thanks. I had the same error with VMware converter running with VC2.5 and the fix you mentioned sorted it out. I did a host reboot.
