VMware Converter ‘A file I/O Error Occurred’
KB ID 0001688 Problem It seems every time I use VMware Converter, there’s some new error that jumps up and makes me stumble! Yesterday the problem was; FAILED: A file I/O error occurred while accessing Solution Some searching told me this is actually a DNS problem, (where the converter could not resolve the DNS name of the machine being converted).
