pluto.uk.nsynergy.com has address 78.129.232.220

Are both configured equal?

Martin,
Have you tried eliminating it being an issue with the plugin, and just
testing with wget or something similar?
Is the IIS server part of a domain? Have you tried checking the
security logs on the server to see if there are any odd entries there?
I do notice a substantial time difference between the execution of one
over the other. The successful run takes 0.69s, whilst the failed run
takes 6.49s, 10 times the execution time. If it is on a domain, could
it be having issues authenticating to a DC?
