Many thanks Jeff,

Looks like I've a little work to do :-)
Lucky I've only got about 12 virtual sites set up so far!
The reason I asked about ftp.xyz.com was that I simply wasn't sure, I
thought it may be an odd one to have and I've certainly no need for it right
now, but I thought it better to get it straigtened out now rather than
later!

Regards,

Phil
