that's correct. so it was probably working in the past when the hostnames
didn't match the usernames but now that they do match, it no longer works.
silly me. given its name i thought it was looking up the name
of an account on the computer not the computer itself. :-)

hi roger,
i tried that and got the following error:
error: (1332, 'LookupAccountName',
'No mapping between account names and security IDs was done.')
according to microsoft's documentation
(http://msdn.microsoft.com/en-us/library/windows/desktop/aa379159%28v=vs.85%29.aspx)
the username should be domainname\username not \\hostname\username but it
also says that a fqdn can be used instead of a windows domain name.
if i use the unqualified hostname (as returned by win32api.GetComputerName()),
it works. so the leading \\ needs to be absent.
and it even works when the windows computer name isn't the same as the dns
hostname.
many thanks for your help. it's all good now. working code is below.
cheers,
raf
