FrontPage 2000 FTP upload fails.

[Chris]

I have been using FP2000 for some time to update three different simple websites on
three different servers.

Recently, FTP uploading (File>Publish Web) just stopped working for all three
sites.

It gets a far as "Listing pages in ftp://ftp.xxxxxx.com:21" and then just throws up
a "425 Can't build data connection" error. This happens with all three different
webs, so it must be FP2000 causing the problem.

I have checked and double-checked that the log-on details are correct.

I can upload the files ok using a separate FTP program, and I can also upload the
files using Microsofts "Visual Web Developer" program, using exactly the same
log-on details as I am using for FP2000

I have run a "Check and repair" on FP2000. So what is there in FP2000 that could
cause such problems, when other programs work ok?
